onSubmit=alert(0) Is Not Working Properly!

Question

While debugging a page, I found out that the JavaScript code onSubmit is not working. I was wondering what is causing this error on the page, it seems to me like there is nothing to cause any trouble with my code. And quite I am confused because I couldn’t understand the error its making, if someone smart could point my error I would gladly appreciate your help, thank you!

Answer 1

`onsubmit` is an event bound to a HTML form element. You applied it on a hidden input, thus the event never fires because the event is meant for the form

That’s wonderful! It took me an hour to figure out, why the output is giving me headache. I thought it’s an error, it just a coding mistake. Thank you, stranger!
