Disable validation of HTML5 form elements

2019-01-01 01:33发布

In my forms, I'd like to use the new HTML5 form types, for example <input type="url" /> (more info about the types here).

The problem is that Chrome wants to be super helpful and validate these elements for me, except that it sucks at it. If it fails the built-in validation, there's no message or indication other than the element getting focus. I prefill URL elements with "http://", and so my own custom validation just treats those values as empty strings, however Chrome rejects that. If I could change its validation rules, that would work too.

I know I could just revert back to using type="text" but I want the nice enhancements using these new types offers (eg: it automatically switches to a custom keyboard layout on mobile devices):

So, is there a way to switch off or customise the automatic validation?

Here is the function I use to prevent chrome and opera from showing the invalid input dialog even when using novalidate.

window.submittingForm = false;
$('input[novalidate]').bind('invalid', function(e) {
    if(!window.submittingForm){
        window.submittingForm = true;
        $(e.target.form).submit();
        setTimeout(function(){window.submittingForm = false;}, 100);
    }
    e.preventDefault();
    return false;
});

Just use novalidate in your form.

<form name="myForm" role="form" novalidate class="form-horizontal" ng-hide="formMain">

Cheers!!!

If you want to disable client side validation for a form in HTML5 add a novalidate attribute to the form element. Ex:

<form method="post" action="/foo" novalidate>...</form>

See https://www.w3.org/TR/html5/sec-forms.html#element-attrdef-form-novalidate

I just wanted to add that using the novalidate attribute in your form will only prevent the browser from sending the form. The browser still evaluates the data and adds the :valid and :invalid pseudo classes.

I found this out because the valid and invalid pseudo classes are part of the HTML5 boilerplate stylesheet which I have been using. I just removed the entries in the CSS file that related to the pseudo classes. If anyone finds another solution please let me know.

Instead of trying to do an end run around the browser's validation, you could put the http:// in as placeholder text. This is from the very page you linked:

Placeholder Text

The first improvement HTML5 brings to web forms is the ability to set placeholder text in an input field. Placeholder text is displayed inside the input field as long as the field is empty and not focused. As soon as you click on (or tab to) the input field, the placeholder text disappears.

You’ve probably seen placeholder text before. For example, Mozilla Firefox 3.5 now includes placeholder text in the location bar that reads “Search Bookmarks and History”:

enter image description here

When you click on (or tab to) the location bar, the placeholder text disappears:

enter image description here

Ironically, Firefox 3.5 does not support adding placeholder text to your own web forms. C’est la vie.

Placeholder Support

IE  FIREFOX SAFARI  CHROME  OPERA   IPHONE  ANDROID
·   3.7+    4.0+    4.0+    ·       ·       ·

Here’s how you can include placeholder text in your own web forms:

<form>
  <input name="q" placeholder="Search Bookmarks and History">
  <input type="submit" value="Search">
</form>

Browsers that don’t support the placeholder attribute will simply ignore it. No harm, no foul. See whether your browser supports placeholder text.

It wouldn't be exactly the same since it wouldn't provide that "starting point" for the user, but it's halfway there at least.

I found a solution for Chrome with CSS this following selector without bypassing the native verification form who can be very useful.

form input::-webkit-validation-bubble-message, 
form select::-webkit-validation-bubble-message,
form textarea::-webkit-validation-bubble-message {
    display:none;
} 

By this way, you can also customise your message...

I get the solution on this page : http://trac.webkit.org/wiki/Styling%20Form%20Controls
