Hi,

I'm loading some content with XHR (aka Ajax) the loaded input elements that have a invalid value assigned are not checked trough the validation process.

so the CSS styling with :invalid is for example not working etc..

is there a way to force the validation process on those elements ?

edit: Browser is Firefox

Thanks.

It will not be digest to send all what I use for you to see it (it will lead to TL;DR)

but here an elements (loaded with XHR that give the problem

<input id="something" name="something" type="text" placeholder="aPlaceholder"  minlength="3" maxlength="32" value="this value is more than the limiation of 32 char" autofocus required>

So normally this element should be invalid and a CSS selector of :invalid should match. but it's not the case because the browser seem to not run the validation check on loaded elements... !?

if we edit manually the input , for example removing one character then the validation process kick-in and the CSS selector work etc..

Thank @[email protected]

it's look like that that code only verify the form when submitting.. I need to check the validity when the element has been loaded.

btw checkValidity() do not solve this issue as it return True when the length is longer than maxlength ! O_o I guess this is were is lying the "bug"

My two cent

For me this is a huge flaw ! I don't understand how we (dev) are we still developing on "standard" that are so f*ck-up..
