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.

Thank @daisyKutter@lemmy.ml

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..

There are several proposed workarounds there, like
