Hi,
I’m loading some content with XHR (aka Ajax) the loaded
inputelements that have a invalidvalueassigned are not checked trough the validation process.so the
CSSstyling with:invalidis 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
So normally this element should be invalid and a CSS selector of
:invalidshould 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 returnTruewhen the length is longer thanmaxlength! 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
https://caniuse.com/constraint-validation
Usually validation is only triggered on change or blur events. Changing the value programmatically doesn’t trigger these events so you need to trigger them yourself.
Thank you @[email protected] that exactly my question… how can I trigger the validation process again ?
Try
form.reportValidity()where form is the form element.
