In Google Chrome some customers are not able to proceed to my payment page.
When trying to submit a form I get this error:
An invalid form control with name='' is not focusable.
This is from the JavaScript console.
I read that the problem could be due to hidden fields having the required attribute.
Now the problem is that we are using .net webforms required field validators, and not the html5 required attribute.
It seems random who gets this error.
Is there anyone who knows a solution for this?
This issue occurs on Chrome if a form field fails validation, but due to the respective invalid control not being focusable the browser's attempt to display the message "Please fill out this field" next to it fails as well.
A form control may not be focusable at the time validation is triggered for several reasons. The two scenarios described below are the most prominent causes:
The field is irrelevant according to the current context of the business logic. In such a scenario, the respective control should be disabled or removed from the DOM or not be marked with the required attribute at that point.
Premature validation may occur due to a user pressing ENTER key on an input. Or a user clicking on a button/input control in the form which has not defined the type attribute of the control correctly. If the type attribute of a button is not set to button, Chrome (or any other browser for that matter) performs a validation each time the button is clicked because submit is the default value of a button's type attribute.
To solve the problem, if you have a button on your page that does something else other than submit or reset, always remember to do this: <button type="button">.
Adding a novalidate attribute to the form will help:
<form name="myform" novalidate>
In your form, You might have hidden input having required attribute:
<input type="hidden" required />
<input type="file" required style="display: none;"/>
The form can't focus on those elements, you have to remove required from all hidden inputs, or implement a validation function in javascript to handle them if you really require a hidden input.
In case anyone else has this issue, I experienced the same thing. As discussed in the comments, it was due to the browser attempting to validate hidden fields. It was finding empty fields in the form and trying to focus on them, but because they were set to display:none;, it couldn't. Hence the error.
I was able to solve it by using something similar to this:
$("body").on("submit", ".myForm", function(evt) {
// Disable things that we don't want to validate.
$(["input:hidden, textarea:hidden, select:hidden"]).attr("disabled", true);
// If HTML5 Validation is available let it run. Otherwise prevent default.
if (this.el.checkValidity && !this.el.checkValidity()) {
// Re-enable things that we previously disabled.
$(["input:hidden, textarea:hidden, select:hidden"]).attr("disabled", false);
return true;
}
evt.preventDefault();
// Re-enable things that we previously disabled.
$(["input:hidden, textarea:hidden, select:hidden"]).attr("disabled", false);
// Whatever other form processing stuff goes here.
});
Also, this is possibly a duplicate of "Invalid form control" only in Google Chrome
In my case the problem was with the input type="radio" required being hidden with:
visibility: hidden;
This error message will also show if the required input type radio or checkbox has a display: none; CSS property.
If you want to create custom radio/checkbox inputs where they must be hidden from the UI and still keep the required attribute, you should instead use the:
opacity: 0; CSS property
None of the previous answers worked for me, and I don't have any hidden fields with the required attribute.
In my case, the problem was caused by having a <form> and then a <fieldset> as its first child, which holds the <input> with the required attribute. Removing the <fieldset> solved the problem. Or you can wrap your form with it; it is allowed by HTML5.
I'm on Windows 7 x64, Chrome version 43.0.2357.130 m.
Not only required field as mentioned in other answers. Its also caused by placing an <input> field in a hidden <div> which holds an invalid value.
Consider below example,
<div style="display:none;">
<input type="number" name="some" min="1" max="50" value="0">
</div>
This throws the same error. So make sure the <input> fields inside hidden <div> doesnt hold any invalid value.
This issue occurs when you provide style="display: none;" and required attribute to the input field, and there will be validation on submit.
for example:
<input type="text" name="name" id="name" style="display: none;" required>
This issue can be resolved by removing required attribute from the input field from your HTML. If you need to add required attribute, add it dynamically. If you are using JQuery, use below code:
$("input").prop('required',true);
If you need to remove this field dynamically,
$("input").prop('required',false);
You can also make use of plain Javascript if you are not using JQuery:
document.getElementById('element_id').removeAttribute('required');
Yet another possibility if you're getting the error on a checkbox input. If your checkboxes use custom CSS which hides the default and replaces it with some other styling, this will also trigger the not focusable error in Chrome on validation error.
I found this in my stylesheet:
input[type="checkbox"] {
visibility: hidden;
}
Simple fix was to replace it with this:
input[type="checkbox"] {
opacity: 0;
}
It can be that you have hidden (display: none) fields with the required attribute.
Please check all required fields are visible to the user :)
For me this happens, when there's a <select> field with pre-selected option with value of '':
<select name="foo" required="required">
<option value="" selected="selected">Select something</option>
<option value="bar">Bar</option>
<option value="baz">Baz</option>
</select>
Unfortunately it's the only cross-browser solution for a placeholder (How do I make a placeholder for a 'select' box?).
The issue comes up on Chrome 43.0.2357.124.
For Select2 Jquery problem
The problem is due to the HTML5 validation cannot focus a hidden invalid element.
I came across this issue when I was dealing with jQuery Select2 plugin.
Solution
You could inject an event listener on and 'invalid' event of every element of a form so that you can manipulate just before the HTML5 validate event.
$('form select').each(function(i){
this.addEventListener('invalid', function(e){
var _s2Id = 's2id_'+e.target.id; //s2 autosuggest html ul li element id
var _posS2 = $('#'+_s2Id).position();
//get the current position of respective select2
$('#'+_s2Id+' ul').addClass('_invalid'); //add this class with border:1px solid red;
//this will reposition the hidden select2 just behind the actual select2 autosuggest field with z-index = -1
$('#'+e.target.id).attr('style','display:block !important;position:absolute;z-index:-1;top:'+(_posS2.top-$('#'+_s2Id).outerHeight()-24)+'px;left:'+(_posS2.left-($('#'+_s2Id).width()/2))+'px;');
/*
//Adjust the left and top position accordingly
*/
//remove invalid class after 3 seconds
setTimeout(function(){
$('#'+_s2Id+' ul').removeClass('_invalid');
},3000);
return true;
}, false);
});
If you have any field with required attribute which is not visible during the form submission, this error will be thrown. You just remove the required attribute when your try to hide that field. You can add the required attribute in case if you want to show the field again. By this way, your validation will not be compromised and at the same time, the error will not be thrown.
It's weird how everyone is suggesting to remove the validation, while validation exists for a reason...
Anyways, here's what you can do if you're using a custom control, and want to maintain the validation:
1st step. Remove display none from the input, so the input becomes focusable
.input[required], .textarea[required] {
display: inline-block !important;
height: 0 !important;
padding: 0 !important;
border: 0 !important;
z-index: -1 !important;
position: absolute !important;
}
2nd step. Add invalid event handler on the input to for specific cases if the style isn't enough
inputEl.addEventListener('invalid', function(e){
//if it's valid, cancel the event
if(e.target.value) {
e.preventDefault();
}
});
It happens if you hide an input element which has a required attribute.
Instead of using display:none you can use opacity: 0;
I also had to use some CSS rules (like position:absolute) to position my element perfectly.
Yea.. If a hidden form control has required field then it shows this error. One solution would be to disable this form control. This is because usually if you are hiding a form control it is because you are not concerned with its value. So this form control name value pair wont be sent while submitting the form.
I came here to answer that I had triggered this issue myself based on NOT closing the </form> tag AND having multiple forms on the same page. The first form will extend to include seeking validation on form inputs from elsewhere. Because THOSE forms are hidden, they triggered the error.
so for instance:
<form method="POST" name='register' action="#handler">
<input type="email" name="email"/>
<input type="text" name="message" />
<input type="date" name="date" />
<form method="POST" name='register' action="#register">
<input type="text" name="userId" />
<input type="password" name="password" />
<input type="password" name="confirm" />
</form>
Triggers
An invalid form control with name='userId' is not focusable.
An invalid form control with name='password' is not focusable.
An invalid form control with name='confirm' is not focusable.
Another possible cause and not covered in all previous answers when you have a normal form with required fields and you submit the form then hide it directly after submission (with javascript) giving no time for validation functionality to work.
The validation functionality will try to focus on the required field and show the error validation message but the field has already been hidden, so "An invalid form control with name='' is not focusable." appears!
Edit:
To handle this case simply add the following condition inside your submit handler
submitHandler() {
const form = document.body.querySelector('#formId');
// Fix issue with html5 validation
if (form.checkValidity && !form.checkValidity()) {
return;
}
// Submit and hide form safely
}
Edit: Explanation
Supposing you're hiding the form on submission, this code guarantees that the form/fields will not be hidden until form become valid. So, if a field is not valid, the browser can focus on it with no problems as this field is still displayed.
There are many ways to fix this like
Add novalidate to your form but its totally wrong as it will remove form validation which will lead to wrong information entered by the users.
<form action="...." class="payment-details" method="post" novalidate>
Use can remove the required attribute from required fields which is also wrong as it will remove form validation once again.
Instead of this:
<input class="form-control" id="id_line1" maxlength="255" name="line1" placeholder="First line of address" type="text" required="required">
Use this:
<input class="form-control" id="id_line1" maxlength="255" name="line1" placeholder="First line of address" type="text">
Use can disable the required fields when you are not going to submit the form instead of doing some other option. This is the recommended solution in my opinion.
like:
<input class="form-control" id="id_line1" maxlength="255" name="line1" placeholder="First line of address" type="text" disabled="disabled">
or disable it through javascript / jquery code dependes upon your scenario.
It will show that message if you have code like this:
<form>
<div style="display: none;">
<input name="test" type="text" required/>
</div>
<input type="submit"/>
</form>
You may try .removeAttribute("required") for those elements which are hidden at the time of window load. as it is quite probable that the element in question is marked hidden due to javascript (tabbed forms)
e.g.
if(document.getElementById('hidden_field_choice_selector_parent_element'.value==true){
document.getElementById('hidden_field').removeAttribute("required");
}
This should do the task.
It worked for me... cheers
There are things that still surprises me... I have a form with dynamic behaviour for two different entities. One entity requires some fields that the other don't.
So, my JS code, depending on the entity, does something like:
$('#periodo').removeAttr('required');
$("#periodo-container").hide();
and when the user selects the other entity:
$("#periodo-container").show();
$('#periodo').prop('required', true);
But sometimes, when the form is submitted, the issue apppears: "An invalid form control with name=periodo'' is not focusable (i am using the same value for the id and name).
To fix this problem, you have to ensurance that the input where you are setting or removing 'required' is always visible.
So, what I did is:
$("#periodo-container").show(); //for making sure it is visible
$('#periodo').removeAttr('required');
$("#periodo-container").hide(); //then hide
Thats solved my problem... unbelievable.
In my case..
ng-show was being used.
ng-if was put in its place and fixed my error.
Wow, a lot of answers here!
If the problem is <input type="hidden" required="true" />, then you can solve this in just a few lines.
The logic is simple and straight-forward:
Mark every required input on page-load with a data-required class.
On submit, do two things: a) Add required="true" to all data-required inputs. b) Remove required="true"` from all hidden inputs.
HTML
<input type="submit" id="submit-button">
Pure JavaScript
document.querySelector('input,textarea,select').filter('[required]').classList.add('data-required');
document.querySelector('#submit-button').addEventListener('click', function(event) {
document.querySelector('.data-required').prop('required', true);
document.querySelector('input,textarea,select').filter('[required]:hidden').prop('required', false);
return true;
}
jQuery
$('input,textarea,select').filter('[required]').addClass('data-required');
$('#submit-button').on('click', function(event) {
$('.data-required').prop('required', true);
$('input,textarea,select').filter('[required]:hidden').prop('required', false);
return true;
}
For Angular use:
ng-required="boolean"
This will only apply the html5 'required' attribute if the value is true.
<input ng-model="myCtrl.item" ng-required="myCtrl.items > 0" />
I found same problem when using Angular JS. It was caused from using required together with ng-hide. When I clicked on the submit button while this element was hidden then it occurred the error An invalid form control with name='' is not focusable. finally!
For example of using ng-hide together with required:
<input type="text" ng-hide="for some condition" required something >
I solved it by replacing the required with ng-pattern instead.
For example of solution:
<input type="text" ng-hide="for some condition" ng-pattern="some thing" >
Not just only when specify required, I also got this issue when using min and max e.g.
<input type="number" min="1900" max="2090" />
That field can be hidden and shown based on other radio value. So, for temporary solution, I removed the validation.
I have seen this question asked often and have come across this 'error' myself. There have even been links to question whether this is an actual bug in Chrome.
This is the response that occurs when one or more form input type elements are hidden and these elements have a min/max limit (or some other validation limitation) imposed.
On creation of a form, there are no values attributed to the elements, later on the element values may be filled or remain unchanged.
At the time of submit, the form is parsed and any hidden elements that are outside of these validation limits will throw this 'error' into the console and the submit will fail. Since you can't access these elements (because they are hidden) this is the only response that is valid.
This isn't an actual fault nor bug. It is an indication that there are element values about to be submitted that are outside of the limits stipulated by one or more elements.
To fix this, assign a valid default value to any elements that are hidden in the form at any time before the form is submitted, then these 'errors' will never occur. It is not a bug as such, it is just forcing you into better programming habits.
NB: If you wish to set these values to something outside the validation limits then use form.addEventListener('submit', myFunction) to intercept the 'submit' event and fill in these elements in "myFunction". It seems the validation checking is performed before "myFunction() is called.
Its because there is a hidden input with required attribute in the form.
In my case, I had a select box and it is hidden by jquery tokenizer using inline style. If I dont select any token, browser throws the above error on form submission.
So, I fixed it using the below css technique :
select.download_tag{
display: block !important;//because otherwise, its throwing error An invalid form control with name='download_tag[0][]' is not focusable.
//So, instead set opacity
opacity: 0;
height: 0px;
}
For other AngularJS 1.x users out there, this error appeared because I was hiding a form control from displaying instead of removing it from the DOM entirely when I didn't need the control to be completed.
I fixed this by using ng-if instead of ng-show/ng-hide on the div containing the form control requiring validation.
Hope this helps you fellow edge case users.

I've stumbled across this issue a couple of times in the last while, where Chrome ignores autocomplete="false" and autocomplete="off". It will now even ignore autocomplete="whatever" or anything you do to trick it, if someone has submitted a form with that random "hack" in it before.
In trying to solve this issue, I came across this StackOverflow question, which doesn't solve the problem if you've submitted a form containing this field before.
EDIT: This is NOT for password fields.
I had this issue with a field that has "number" in the name and this triggering the CreditCard Autocomplete Dialog. This solution helped me get rid of it.
Even though this is not the intended use of the option, I think this is unlikely to break and works without JavaScript Hacks. A one time code won't trigger an autocomplete so I treat the fields that are not supposed to autocomplete as one time codes.
<input type="text" name="number" autocomplete="one-time-code" />
This did the trick for me. I tested it in Chrome 87.0.4280.141 and it works fine.
autocomplete="new-password" and set placeholder attribute with some text works for me.
<input name="name1" placeholder="Nº" type="text" autocomplete="new-password" />
Everytime I found a solution Chrome throws a spanner in the works again.
No longer working
autocomplete="new-*"
add an offscreen positioned bogus input element style="position: fixed;top:-100px;left:-100px;" as first <form> element
set <form autocomplete="off">
use <textarea> and style it as a field
Working solution (15 jul 2021)
Append a dummy <input> without a name attribute and make the original <input> type="hidden"
HTML
<input type="hidden" name="myfield" class="no-autofill"> <input>
Note that any events, (click, blur, focus) that show your custom
autofill should be added to the visible <input> element.
Then add a change event to sync the value to the hidden input.
const fields = document.querySelectorAll('input.no-autofill');
for (const field of fields) {
const dummy = field.nextElementSibling;
dummy.addEventListener('change',e => {
field.value = e.target.value;
});
}
Ow, before implementing. Make sure you visit the Chromium bug tracker
and tell the Chrome Developers why following the standard is important. So one day we might be able to just use:
<input name="myfield" autocomplete="off">
its work in my local machine try it...
<input type="email" class="form-control" id="email" name="email" placeholder="Enter Email" readonly onfocus="this.removeAttribute('readonly');" style="background-color: white;">
It's November 2021, and none of the non-javascript solutions mentioned worked for my address-related field. What did work was actually changing the text in the label.
The Autocomplete dialog in Chrome was shown if:
The word "Address" is in the label at the start or end; and
There are at least two other address fields (seemingly anywhere in the page)
EDIT: If you put a zero-width joiner character entity in the middle of the word 'Address' in the label, the autocomplete dialog is suppressed!
i.e. set the label to Address
html, body {
font-family: 'Helvetica', Sans-Serif;
font-weight: 200;
line-height: 1.5em;
padding: 1em;
}
<div class="addressDiv">
<div>
<label>Focus on this field...Address</label>
<div>
<input autocomplete="off" type="text" aria-autocomplete="none" autocapitalize="none" />
</div>
</div>
<div>
<label>State</label>
<div>
<input autocomplete="address-level1" type="text" value="">
</div>
</div>
<div>
<label>City</label>
<div>
<input autocomplete="address-level2" type="text" value="">
</div>
</div>
</div>
<p>
See this JSFiddle
</p>
Read the note at the bottom before using this method
After struggling for a long time, I made it work reliably this way:
It is important that your input type is 'text'!!
define a css class
input.hidden-password {
-webkit-text-security: disc;
}
Then in your form, set autocomplete off, input types = 'text' and add the class to the input.
<form autocomplete="off">
<input
type = "text" // <----This is important
class = "hidden-password"
/>
</form>
C'mon Google, let us take control over our inputs! My client requires passwords to be changed very often and auto fill IS A BIG NO NO!
IMPORTANT NOTE Do not use this for login or any other place where security is required. I used this for a form within my app where the user was already authenticated and security was not required.
For Me, the problem only occurs, if I have multiple fields with the same value for autocomplete. If I set the value to a random number (Math.random()), no autocomplete is happening. I think it would also be possible to use an otherwise unique string.
To prevent 'manage addresses' level of of chrome popup: autocomplete='chrome-off'
To prevent autosuggest popup, if you can swing it: EXCLUDE name and id attributes.
Try to make your input readonly, enable it after focus
<input readonly="readonly" onfocus="this.removeAttribute('readonly');" type="text" value="test">
here is JS solution that works at this point in time for me:
<input name="name" type="text"
onfocus="this.__name = this.getAttribute('name'); this.removeAttribute('name')"
onblur="this.setAttribute('name',this.__name)"
>
The above js code stores input name to this.__name and removes the name onfocus later onblur name is restored so forms can work as expected, but chrome does not autofill.
No known attribute value is working in form tag. I have tried them all: do-not-show-ac, chrome-off, new-password, off...
The only way i found is by adding autocomplete='new-password' to every input component. To do it globaly, i am using this jquery:
<script>
$('input').attr('autocomplete', 'new-password');
</script>
The best way is to use JavaScript to skip browser's behavior, disableautofill.js does this.
You can try https://github.com/terrylinooo/disableautofill.js
<script src="https://cdn.jsdelivr.net/npm/disableautofill#2.0.0/dist/disableautofill.min.js"></script>
Usage:
var daf = new disableautofill({
'form': '#testForm', // Form id
'fields': [
'.test-pass', // password
'.test-pass2' // confirm password
],
'debug': true,
'callback': function() {
return checkForm(); // Form validator
}
});
daf.init();
How about just never submit the form? Nothing to remember!
Your app probably doesn't work without javascript anyway, right?
In fact, don't use a form at all, just collect the input values, serialize and do an ajax call.
$('#mybutton').on('click', function (e) {
$.ajax({
type: "POST",
url: 'mybackend',
data: $('#formdiv input').serialize(),
success: function (data) ...
Mind you, this is not a well tested idea, just something I have observed when I wanted autofill, and which I have not seen suggested in any of the many threads dealing with this issue.
I just resolved a related issue - it was forcing Chrome Autofill on an address field (Google Places Autocomplete, specifically) and no other solutions were working.
Eventually, we changed the nearest label to it from saying "Business Address" to being blank and set its text via CSS
#gmapsSearchLabel:after {
content: "Business Address";
}
And without a nearby label "saying" address, it stopped forcing Autofill.
A solution that works for me is to place a zero-width-white-space character into the placeholder text, so for example:
placeholder="Enter your address" becomes
placeholder="Enter your a[ZWSP]ddress"
Chrome is then unable to find "address" and skips autocomplete suggestions.
You can copy the character ( don't use the html entity etc. ) over at CSS Tricks. Here is the word "address" with the ZWSP character after the letter "a":
address
Dirty answer ,
edit "selectorForYourInputs" and works just fine, cross browser tested, max overhead 50ms, user never notice any performance lag:
counter = 0;
emptySearchboxInterval = setInterval(() => {
$(selectorForYourInputs).val("");
counter++;
counter == 100 ? clearInterval(emptySearchboxInterval) : null;
}, 20);
I have several textboxes on the form that are marked with required="required" attribute (html5).
There are two buttons. The first button should cause validation, the second should not.
ValidationGroup doesn't work in this case.
How is it possible to solve this issue?
UPD: To use required attribute is the requirement so I cannot avoid it.
<input type=submit formnovalidate>
Submits the form without validation.
I have read a bit on this, but I can't seem to find anything solid about how different browsers treat things.
A readonly element is just not editable, but gets sent when the according form submits. A disabled element isn't editable and isn't sent on submit. Another difference is that readonly elements can be focused (and getting focused when "tabbing" through a form) while disabled elements can't.
Read more about this in this great article or the definition by w3c. To quote the important part:
Key Differences
The Disabled attribute
Values for disabled form elements are not passed to the processor method. The W3C calls this a successful element.(This works similar to
form check boxes that are not checked.)
Some browsers may override or provide default styling for disabled form elements. (Gray out or emboss text) Internet Explorer
5.5 is particularly nasty about this.
Disabled form elements do not receive focus.
Disabled form elements are skipped in tabbing navigation.
The Read Only Attribute
Not all form elements have a readonly attribute. Most notable, the <SELECT> , <OPTION> , and <BUTTON> elements do not have readonly
attributes (although they both have disabled attributes)
Browsers provide no default overridden visual feedback that the form element is read only. (This can be a problem… see below.)
Form elements with the readonly attribute set will get passed to the form processor.
Read only form elements can receive the focus
Read only form elements are included in tabbed navigation.
No events get triggered when the element is having disabled attribute.
None of the below will get triggered.
$("[disabled]").click( function(){ console.log("clicked") });//No Impact
$("[disabled]").hover( function(){ console.log("hovered") });//No Impact
$("[disabled]").dblclick( function(){ console.log("double clicked") });//No Impact
While readonly will be triggered.
$("[readonly]").click( function(){ console.log("clicked") });//log - clicked
$("[readonly]").hover( function(){ console.log("hovered") });//log - hovered
$("[readonly]").dblclick( function(){ console.log("double clicked") });//log - double clicked
Disabled means that no data from that form element will be submitted when the form is submitted. Read-only means any data from within the element will be submitted, but it cannot be changed by the user.
For example:
<input type="text" name="yourname" value="Bob" readonly="readonly" />
This will submit the value "Bob" for the element "yourname".
<input type="text" name="yourname" value="Bob" disabled="disabled" />
This will submit nothing for the element "yourname".
Same as the other answers (disabled isn't sent to the server, readonly is) but some browsers prevent highlighting of a disabled form, while read-only can still be highlighted (and copied).
http://www.w3schools.com/tags/att_input_disabled.asp
http://www.w3schools.com/tags/att_input_readonly.asp
A read-only field cannot be modified. However, a user can tab to it, highlight it, and copy the text from it.
If the value of a disabled textbox needs to be retained when a form is cleared (reset), disabled = "disabled" has to be used, as read-only textbox will not retain the value
For Example:
HTML
Textbox
<input type="text" id="disabledText" name="randombox" value="demo" disabled="disabled" />
Reset button
<button type="reset" id="clearButton">Clear</button>
In the above example, when Clear button is pressed, disabled text value will be retained in the form. Value will not be retained in the case of input type = "text" readonly="readonly"
The readonly attribute can be set to keep a user from changing the value until some other conditions have been met while the disabled attribute can be set to keep a user from using the element
The difference between disabled and readonly is that read-only controls can still function and are still focusable, anddisabled controls can not receive focus and are not submitted with the form
I discovered something surprising:
<html>
<head>
<script type="text/javascript">
function f()
{
document.getElementById("h").value++;
document.getElementById("x").value++;
}
</script>
</head>
<body>
<form>
<input type="hidden" name="hidden" id="h" value="5"/>
<input type="text" id="x" value="5"/>
<input name='clear' type='reset' id='clear' value='Clear'>
</form>
<button type="button" onclick="f()">Increment</button>
<button type="button" onclick="alert(document.getElementById('h').value)">Show hidden</button>
</body>
</html>
Trying this in Firefox 4.0.1, clicking clear always resets the text input to 5, but never resets the hidden field.
I (and others) did not expect this behavior at all: we expected the hidden value to get reset too!
Can anyone point to either documentation or specs that explain why the hidden input is treated differently by the reset button?
Explanations as to why such behavior is desirable are also welcome.
FWIW, I think I can put together the full story from the answers and comments.
Usage rationale: The clear button is intended for clearing user input, and since hidden inputs are not directly accessible by the user, it doesn't make sense to allow the user to reset the hidden input's value.
Documentation and behavior:
The bug report that AR pointed out is explicit about what is happening: The hidden field's value's mode is default, as is intended in the specs.
Particularly, this means that changing the value (as in the sample code in the question) changes the default value, and the reset button resets input fields to the default value, hence there is no change.
The behavior for the text input is different (even though its value is also changed programmatically) because its value's mode is not default but value, which means that there is a distinction between the default value of the input and the current value.
The user can't see or modify the hidden field, therefore it wouldn't make any sense for them to be able to clear it by pressing a button.
When clicking on reset, the browser goes and check the default value in the DOM tree, not in the HTML page.
Your Javascript modifies the DOM. You should try to replace your RESET button with a custom button that calls a Javascript that does two things:
reset normally.
set the hidden field to 5.
I came here because I bumped into this same issue. However, upon further reflection it is (usually) a very desired behavior.
The hidden field is most commonly used for storing information that was sent by the server when the page loaded.
Although, it can also be used by the script to enter some runtime-calculated entries, resetting hidden fields can cause trouble when not intended.
It's a bit of a fudge, but if you want a hidden input that will reset using the formElement.reset() function, give it a display: none style instead.
<input type="text" name="myHiddenInput" value="default value" style="display: none">
I am using an <input readonly="readonly">, styled as normal text to remove the appearance of an interactive field, but still display the value.
This is very useful to prevent a user from editing a field, while still being able to post the value. I realize this is a convenience method and that there are several workarounds, but I want to use this method.
Problem: The blinking caret still appears when the field is clicked/focused. (At least in FF and IE8 on Win7)
Ideally, I would like it to behave as it normally does, focusable, but without the blinking caret.
Javascript solutions welcome.
On mine there is no caret or so:
<input type="text" value="test" readonly="readonly" >
Take a look at this: http://www.cs.tut.fi/~jkorpela/forms/readonly.html
Sorry, now I understand your problem.
Try this:
<input type="text" value="test" onfocus="this.blur()" readonly="readonly" >
You can use this in your css, but it will not focus:
[readonly='readonly'] {
pointer-events: none;
}
You can remove the blinking caret by specify the css attribute into transparent
caret-color: transparent;
you can test the result here
It can be done using html and javascript
<input type="text" onfocus="this.blur()" readonly >
or jQuery
$(document).on('focus', 'input[readonly]', function () {
this.blur();
});
the only way i found for this was
//FIREFOX
$('INPUT_SELECTOR').focus(function () {
$(this).blur();
});
//INTERNET EXPLORER
$('INPUT_SELECTOR').attr('unselectable', 'on');
KENDO
$('.k-ff .k-combobox>span>.k-input').focus(function () {
$(this).blur();
});
$('.k-ie .k-combobox>span>.k-input').attr('unselectable', 'on');
The onfocus/blur method works ok to remove the cursor from a readonly field, but the browser does not automatically refocus on the next field, and you may lose focus altogether, which is not what the user usually expects. So, if this is required, you can use plain javascript to focus on the next field you want, but you have to specify the next field:
<input type="text" name="readonly-field" value="read-only"
readonly onfocus="this.form.NextField.focus()">
Where 'NextField' is the name of the field to goto. (Alternatively, you could provide some other means to locate the next field). Obviously, this is more involved if you want to navigate to some non-visible UI element, like a tab-panel, as you will need to arrange this as well.
Easy!
Just add disabled to input and it will not be clickable (focused)
