I have this simple input field for e-mail addresses:
<form>
<input type="email" placeholder="E-Mail" required>
<input type="submit" value="Send" />
</form>
If you write "max#mail.de", you can submit the form, because the email is valid.
If you write "max#.de", you can't submit the form, because the email is invalid.
But!
If you write "max#i9", you can submit the form, too. But the mail is invalid. Why?
And how can I fix it?
Because max#i9 is a valid email as it stated in this article.
You can "fix" it by adding your own email pattern, see this tutorial:
<form>
<input type="email" pattern="/^[a-zA-Z0-9.!#$%&'*+/=?^_`{|}~-]+#[a-zA-Z0-9-]+(?:\.[a-zA-Z0-9-]+)*$/" required />
</form>
Here's a more detailed question about Why does HTML5 form validation allow emails without a dot?
<form>
<input pattern="[a-zA-Z0-9.-_]{1,}#[a-zA-Z.-]{2,}[.]{1}[a-zA-Z]{2,}$"
type="text" required />
<input type="submit" value="Send" />
</form>
This is because HTML5 type="email" validator is only find # symbol in your input string. If it is found your form will submitted else it won't submitted.
To avoid this you have to use javaSctipt form Validation like this :-
function validateemail()
{
var x=document.myform.email.value;
var atposition=x.indexOf("#");
var dotposition=x.lastIndexOf(".");
if (atposition<1 || dotposition<atposition+2 || dotposition+2>=x.length){
alert("Please enter a valid e-mail address \n atpostion:"+atposition+"\n dotposition:"+dotposition);
return false;
}
}
HTML can't help you with data validation, you can learn js to do that
I am trying to change the language of the error message in the html5 form field.
I have this code:
<input type="text" name="company_name" oninvalid="setCustomValidity('Lütfen işaretli yerleri doldurunuz')" required />
but on submit, even the field is not blank, I still get the error message.
I tried with <input type="text" name="company_name" setCustomValidity('Lütfen işaretli yerleri doldurunuz') required />
but then the english message is displayed. Anyone know how can I display the error message on other language?
Regards,Zoran
setCustomValidity's purpose is not just to set the validation message, it itself marks the field as invalid. It allows you to write custom validation checks which aren't natively supported.
You have two possible ways to set a custom message, an easy one that does not involve Javascript and one that does.
The easiest way is to simply use the title attribute on the input element - its content is displayed together with the standard browser message.
<input type="text" required title="Lütfen işaretli yerleri doldurunuz" />
If you want only your custom message to be displayed, a bit of Javascript is required. I have provided both examples for you in this fiddle.
your forget this in oninvalid, change your code with this:
oninvalid="this.setCustomValidity('Lütfen işaretli yerleri doldurunuz')"
<form><input type="text" name="company_name" oninvalid="this.setCustomValidity('Lütfen işaretli yerleri doldurunuz')" required /><input type="submit">
</form>
HTML:
<form id="myform">
<input id="email" oninvalid="InvalidMsg(this);" name="email" oninput="InvalidMsg(this);" type="email" required="required" />
<input type="submit" />
</form>
JAVASCRIPT :
function InvalidMsg(textbox) {
if (textbox.value == '') {
textbox.setCustomValidity('Lütfen işaretli yerleri doldurunuz');
}
else if (textbox.validity.typeMismatch){
textbox.setCustomValidity('Lütfen işaretli yere geçerli bir email adresi yazınız.');
}
else {
textbox.setCustomValidity('');
}
return true;
}

This work for me.
<input oninvalid="this.setCustomValidity('custom text on invalid')" onchange="this.setCustomValidity('')" required>
onchange is a must!
I know this is an old post but i want to share my experience.
HTML:
<input type="text" placeholder="Username or E-Mail" required data-required-message="E-Mail or Username is Required!">
Javascript (jQuery):
$('input[required]').on('invalid', function() {
this.setCustomValidity($(this).data("required-message"));
});
This is a very simple sample. I hope this can help to anyone.
TLDR: Usually, you don't need to change the validation message but if you do use this:
<input
oninvalid="this.setCustomValidity('Your custom message / 您的自定义信息')"
oninput="this.setCustomValidity('')"
required="required"
type="text"
name="text"
>
The validation messages are coming from your browser and if your browser is in English the message will be in English, if the browser is in French the message will be in French and so on.
If you an input for which the default validation messages doesn't work for you, the easiest solution is to provide your custom message to setCustomValidity as a parameter.
...
oninvalid="this.setCustomValidity('Your custom message / 您的自定义信息')"
...
This is a native input's method which overwrites the default message. But now we have one problem, once the validation is triggered, the message will keep showing while the user is typing. So to stop the message from showing you can set the validity message to empty string using the oninput attribute.
...
oninput="this.setCustomValidity('')"
...
//Dynamic custome validation on all fields
//add validate-msg attr to all inputs
//add this js code
$("form :input").each(function(){
var input = $(this);
var msg = input.attr('validate-msg');
input.on('change invalid input', function(){
input[0].setCustomValidity('');
if(!(input[0].validity.tooLong || input[0].validity.tooShort)){
if (! input[0].validity.valid) {
input[0].setCustomValidity(msg);
}
}
});
});
<input type="text" id="inputName" placeholder="Enter name" required oninvalid="this.setCustomValidity('Your Message')" oninput="this.setCustomValidity('') />

For the lost souls who are seeking a way to fully localize their error messages, see the snippet below. In short, you have to switch over the properties of event.target.validity and override the corresponding error message using event.target.setCustomValidity(message). If you just care about the empty field case as OP, just consider the case of valueMissing.
Note that the handler is passed in the React way, but other answers already covered how to do it in vanilla JS.
For the meaning of each validity state and how to implement customized error messages, see MDN: Validating forms using JavaScript.
const handleInvalidForm = (event) => {
const { patternMismatch,
tooLong,
tooShort,
rangeOverflow,
rangeUnderflow,
typeMismatch,
valid,
valueMissing } = event.target.validity;
if (patternMismatch)
event.target.setCustomValidity('...');
else if (tooLong)
event.target.setCustomValidity('...');
else if (tooShort)
event.target.setCustomValidity('...');
else if (rangeOverflow)
event.target.setCustomValidity('...');
else if (rangeUnderflow)
event.target.setCustomValidity('...');
else if (typeMismatch)
event.target.setCustomValidity('...');
else if (valid)
event.target.setCustomValidity('...');
else if (valueMissing)
event.target.setCustomValidity('...');
}
// ...
<form onSubmit={handleFormSubmit}
onInvalid={handleInvalidForm}
>
{emailTextField}
{passwordTextField}
{signInButton}
</form>
<input type="text" id="inputName" placeholder="Enter name" required oninvalid="this.setCustomValidity('Please Enter your first name')" >

Do it using JS. Grab the class of the error message, and change it's content for whereever it appears.
var myClasses = document.getElementsByClassName("wpcf7-not-valid-tip");
for (var i = 0; i < myClasses.length; i++) {
myClasses[i].innerHTML = "Bitte füllen Sie das Pflichtfeld aus.";
}
<form>
<input
type="text"
name="company_name"
oninvalid="this.setCustomValidity('Lütfen işaretli yerleri doldurunuz')"
required
/><input type="submit" />
</form>
I have a div
<div id="force_id"></div>
This prints an id for each product on the page. Ex: 26588
How do I assign it to a hidden input value ?
<input name="" id="deger" type="hidden" value="<div id="force_id"></div>">
Not like of course :=)
First off all I think you question ambiguous and what ever you are trying to achieve through this kind of tag might not be a good way to do. I suggest you to look for alternative ways if possible.
<input name="" id="deger" type="hidden" value="<div id="force_id"></div>">
But if you insist this can be easily done. Treat the value like any other string value you would insert inside a div but this time you will need to escape the quote character as below
$("#deger").val('<div id=\"force_id\"></div>');
Try this
$('#deger').val($('#force_id').text());
see the code snippet below
function doIt() {
$('#deger').val($('#force_id').text());
}
// Just for testing what happens
var degerEl = document.getElementById('deger');
var resultEl = document.getElementById('result');
var doItBtn = document.getElementById('doItBtn');
doItBtn.addEventListener('click', doItOnClickCallback);
setResultElValue();
function doItOnClickCallback() {
doIt();
setResultElValue();
}
function setResultElValue() {
resultEl.value = degerEl.outerHTML;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<input name="" id="deger" type="hidden" value="">
<div id="force_id">26588</div>
<!-- Just for testing what happens -->
<button id="doItBtn">Do it</button><br/>
<textarea readonly id="result" style="font-family:monospace;width:400px"></textarea>
I want to have a box in HTML such as this one:
Particular thing, I need to do this using only HTML (no PHP or particular langage requiring server, or particular installation).
The reason for this is that it is meant to be used for HTML pages that will be opened from a USB key, not a website, and it has to be usable by any non-expert person. So no web-server configuration or installation required, such as what would be required for PHP, if I am right.
Think about not using a Form, but just using a Javascript function.
I'm not sure if this probably is not possible due to security reasons, but it could be a solution...
function redirect() {
var input = document.getElementById("stuff");
window.location = input.value;
}
<span>NOM:</span>
<input type="text" id="stuff"></input>
<br>
<input type="button" onclick="redirect()" value="Submit"></input>
I managed to do what I needed thanks to Anders Anderson's answer. Here is the code for those interested in doing similar thing. First, for the Javascript
function redirect() {
var answergiven = document.getElementById("answergiven");
var realanswer = document.getElementById("realanswer");
var nextpage = document.getElementById("nextpage");
if(answergiven.value.toLowerCase() == realanswer.value.toLowerCase()){
window.location = nextpage.value;
}
else{
alert('Wrong answer, please try again.');
}
return false; // prevent further bubbling of event
}
And for the HTML part, there are two hidden variables that determine the real answer, and the next page to go to, and the text field for the answer
<form name="myform" onSubmit="return redirect()">
<span>Réponse:</span>
<input type="text" id="answergiven" />
<input name="tosubmit" type="submit" value="Submit" />
<input type="hidden" id="realanswer" value="theanswer" />
<input type="hidden" id="nextpage" value="thenextpage.html" />
</form>
How can I display the icon "valid", if the "comfirm password" field text is identic to "password" text? Simillar to the name and email fields in the example.
Here is the css code for email verification and name:
input[type=text]:required:valid,[type=email]:required:valid,textarea:required:valid{
background:url(valid.png) 90% center no-repeat #FFF ;
}
Example:

CSS is not a programming language.
You have to validate your fields on server-side or even on client-side with Javascript.
With the current HTML5 implemation in modern browser you can check for the value of inputs. But as far as i know you can't check for the same value only with pure css.
<input type="password" id="pass" name="pass" required pattern="[A-Z]{3}[0-9]{4}"
title="Password numbers consist of 3 uppercase letters followed by 4 digits."/>
Take a look at The constraint validation api
Here is an example of how you can check emails for similarity using the api mentioned above.
<label>Email:</label>
<input type="email" id="email_addr" name="email_addr">
<label>Repeat Email Address:</label>
<input type="email" id="email_addr_repeat" name="email_addr_repeat" oninput="check(this)">
<script>
function check(input) {
if (input.value != document.getElementById('email_addr').value) {
input.setCustomValidity('The two email addresses must match.');
} else {
// input is valid -- reset the error message
input.setCustomValidity('');
}
}
</script>
