<input type="text" required>
$('input').blur(function () {
console.log($('input')[0].checkValidity());
});
When I typed a space, the console gives a true. This is very confuse...
Attibute required checks only if there is any character in input (also whitespaces).
If you want to check against blanks you could use pattern.
<input type="text" pattern="\S+" required>
you can use the html5 pattern
i give you an example but you can put what you want
$('input').blur(function () {
console.log($('input')[0].checkValidity());
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<!-- this pattern don't allow to put a space in th input-->
<input type="text" pattern="^((?!\s).)*$" required>

I have an input type for contact number:
<input type="number" name="usercontact" placeholder="Contact Number" pattern="[0-9]{8,20}" />
I already put the pattern [0-9]{8,20} and i assume it don't allow other characters
But somehow e, and . (dot) able to pass through, why so? How should i only allow numbers only?
Try this
<input
type="number"
name="username"
placeholder="Username"
pattern="[0-9]{1,15}"
id="username">
Input type number can accept e or E and floating point numbers , negative symbols.
Pattern can be used for the validation.You can check if the entered value is valid.
According to This the pattern attribute applies when the value of the type attribute is text, search, tel, url, email, or password, otherwise it is ignored.But this works in some browser.
$('#numericInput').on('change keyup', function(event) {
if ( event.target.validity.valid ) {
$('#errorMsg').text($(this).val());
} else {
$('#errorMsg').text('invalid');
}
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<form method="post">
<input type="number" name="usercontact" placeholder="Contact Number" pattern="[0-9]{8,20}" id="numericInput" />
<p id="errorMsg"></p>
<button type="submit">submit</button>
</form>
I am quite new to this HTML Input Control.
So I want to add "required" attribute to intlTelInput control. Adding the attribute in conventional way i.e
<input type="tel" name="mobile" id="mobile-number" required="required">
is not working.
Can anyone guide me through the process of adding validation to this control.
I have included following css:
<link rel="stylesheet" href="plugins/intl-tel/css/intltelinput.min.css">
Then added the control:
<label>Enter your mobile number</label>
<input type="tel" name="mobile" id="mobile-number" required="required">
And then at end of file I included the script file:
<script src="assets/plugins/intl-tel/js/intltelinput.min.js"></script>
To add default country I have added following js:
(function($){
$(document).ready(function() {
if (typeof $.fn.intlTelInput !== 'undefined') {
$("#mobile-number").intlTelInput({
defaultCountry: "in",
preferredCountries: ["in"]
});
}
});
})(window.jQuery);
Thanks
Try to use the following code:
change type to text
add only a required attribute
Notes: You could use the pattern attribute for phone number in case you need it.
<form action="/action_page.php">
<input type="text" name="mobile" id="mobile-number" required>
<input type="submit">
</form>
I have an HTML form. I would like to show that some of the fields are required by making them bold. In principle, should this go into the CSS rather than HTML? How would you do it?
<form action="doit" id="doit" method="post">
<label>
Name
<input id="name" name="name" type="text" />
</label>
<label>
Phone number
<input id="phone" name="phone" type="text" />
</label>
<label>
Year
<input id="year" name="year" type="text" />
</label>
</form>
Just of the top of my head, I think that if you're willing to use HTML5 and use the <input type="text" name="year" required> property, that you should be able to do:
input:required{
font-weight:bold;
}
And of course, you could go wild here and start throwing around borders and all sorts of stuff to make it really stand out.
Singularity's answer is perfectly valid. For the sake of completion, if you're not willing to use HTML5's required attribute, I would recommend adding a class by the same name to the inputs that are required.
<input type="text" name="firstname" class="required">
input.required {
font-weight: bold;
}
You can further use that class as a selector in your Javascript where you enforce the rule.
$(form).submit(function() {
$('input.required').each(function() {
if ($(this).val() === '') return false;
});
});
To answer the other question you were asking: the bold directive should go in CSS since it is purely presentational.
For example I have a textfield. The field is mandatory, only numbers are required and length of value must be 10. When I try to submit form with value which length is 5, the default error message appears: Please match the requested format
<input type="text" required="" pattern="[0-9]{10}" value="">
How can I change HTML form validation errors default messages?
If the 1st point can be done, is there a way to create some property files and set in that files custom error messages?
This is the JavaScript solution:
<input type="text"
pattern="[a-zA-Z]+"
oninvalid="setCustomValidity('Please enter Alphabets.')"
onchange="try{setCustomValidity('')}catch(e){}" />
The "onchange" event needs when you set an invalid input data, then correct the input and send the form again.
I've tested it on Firefox, Chrome and Safari.
But for Modern Browsers:
Modern browsers didn't need any JavaScript for validation.
Just do it like this:
<input type="text"
pattern="[a-zA-Z]+"
title="Please enter Alphabets."
required="" />
When using pattern= it will display whatever you put in the title attrib, so no JS required just do:
<input type="text" required="" pattern="[0-9]{10}" value="" title="This is an error message" />
<input type="text" pattern="[a-zA-Z]+"
oninvalid="setCustomValidity('Plz enter on Alphabets ')" />
I found this code in another post.
HTML:
<input type="text" pattern="[0-9]{10}" oninvalid="InvalidMsg(this);" name="email" oninput="InvalidMsg(this);" />
JAVASCRIPT :
function InvalidMsg(textbox) {
if(textbox.validity.patternMismatch){
textbox.setCustomValidity('please enter 10 numeric value.');
}
else {
textbox.setCustomValidity('');
}
return true;
}
Fiddle Demo
To prevent the browser validation message from appearing in your document, with jQuery:
$('input, select, textarea').on("invalid", function(e) {
e.preventDefault();
});
you can remove this alert by doing following:
<input type="text" pattern="[a-zA-Z]+"
oninvalid="setCustomValidity(' ')"
/>
just set the custom message to one blank space
you can change them via constraint validation api: http://www.w3.org/TR/html5/constraints.html#dom-cva-setcustomvalidity
if you want an easy solution, you can rock out civem.js, Custom Input Validation Error Messages JavaScript lib
download here: https://github.com/javanto/civem.js
live demo here: http://jsfiddle.net/hleinone/njSbH/
The setCustomValidity let you change the default validation message.Here is a simple exmaple of how to use it.
var age = document.getElementById('age');
age.form.onsubmit = function () {
age.setCustomValidity("This is not a valid age.");
};
I Found a way Accidentally Now:
you can need use this: data-error:""
<input type="username" class="form-control" name="username" value=""
placeholder="the least 4 character"
data-minlength="4" data-minlength-error="the least 4 character"
data-error="This is a custom Errot Text fot patern and fill blank"
max-length="15" pattern="[A-Za-z0-9]{4,}"
title="4~15 character" required/>
I found a bug on Mahoor13 answer, it's not working in loop so I've fixed it with this correction:
HTML:
<input type="email" id="eid" name="email_field" oninput="check(this)">
Javascript:
function check(input) {
if(input.validity.typeMismatch){
input.setCustomValidity("Dude '" + input.value + "' is not a valid email. Enter something nice!!");
}
else {
input.setCustomValidity("");
}
}
It will perfectly running in loop.
This is work for me in Chrome
<input type="text" name="product_title" class="form-control"
required placeholder="Product Name" value="" pattern="([A-z0-9À-ž\s]){2,}"
oninvalid="setCustomValidity('Please enter on Producut Name at least 2 characters long')" />
To set custom error message for HTML validation use,
oninvalid="this.setCustomValidity('Your custom message goes here.')"
and to remove this message when user enters valid data use,
onkeyup="setCustomValidity('')"
As you can see here:
html5 oninvalid doesn't work after fixed the input field
Is good to you put in that way, for when you fix the error disapear the warning message.
<input type="text" pattern="[a-zA-Z]+"
oninvalid="this.setCustomValidity(this.willValidate?'':'your custom message')" />
I want to provide the user with a hint on what he needs to enter into my text field. However, when I set the value, it does not disappear once a user clicks on the text field. How can you make it disappear?
<form action="input_password.htm">
<p>Username:<br><input name="Username" value="Enter username.." type="text" size="20" maxlength="20"></p>
</form>
With a bit of JavaScript:
<input
value="Enter username..."
onfocus="if (this.value === 'Enter username...') this.value=''" ... />
HTML5 has a nice attribute for this, called placeholder:
<input placeholder="Enter username.." ... />
but this attribute is not supported in old browsers.
the best way to give a hint is placeholder like this:
<input.... placeholder="hint".../>
You'd need attach an onFocus event to the input field via Javascript:
<input type="text" onfocus="this.value=''" value="..." ... />
I think for your situation, the easy and simple for your html input , you can
probably add the attribute title
<input name="Username" value="Enter username.." type="text" size="20" maxlength="20" title="enter username">
With HTML5, you can now use the placeholder attribute like this:
<form action="demo_form.asp">
<input type="text" name="fname" placeholder="First name"><br>
<input type="text" name="lname" placeholder="Last name"><br>
<input type="submit" value="Submit">
</form>

I have the same problem, and I have add this code to my application and its work fine for me.
step -1 : added the jquery.placeholder.js plugin
step -2 :write the below code in your area.
$(function () {
$('input, textarea').placeholder();
});
And now I can see placeholders on the input boxes!
This is exactly what you want
$(document).tooltip({ selector: "[title]",
placement: "top",
trigger: "focus",
animation: false});
<form id="form">
<label for="myinput1">Browser tooltip appears on hover but disappears on clicking the input field. But this one persists while user is typing within the field</label>
<input id="myinput1" type="text" title="This tooltip persists" />
<input id="myinput2" type="text" title="This one also" />
</form>
[ref]
If you mean like a text in the background, I'd say you use a label with the input field and position it on the input using CSS, of course. With JS, you fade out the label when the input receives values and fade it in when the input is empty. In this way, it is not possible for the user to submit the description, whether by accident or intent.
If you don't insist on the hint being displayed inside the input field, a modern solution would use a label element with the for attribute referring to the id of the input field, like this:
<form action="input_password.htm">
<label for="username" title="This is your user name...">Username: </label><input id="username" name="Username" type="text" size="20" maxlength="20"></p>
</form>
If you click the label, the input field will get the input focus.
If you hover over the label, it will show a longer explanation.
Generally the label should describe well enough what the user has to enter (in the case of user name it should be very much obvious).
Define tooltip text
<input type="text" id="firstname" name="firstname" tooltipText="Type in your firstname in this box">
Initialize and configure the script
<script type="text/javascript">
var tooltipObj = new DHTMLgoodies_formTooltip();
tooltipObj.setTooltipPosition('right');
tooltipObj.setPageBgColor('#EEE');
tooltipObj.setCloseMessage('Exit');
tooltipObj.initFormFieldTooltip();
</script>
