IE Debugging JS

Question

JavaScript

Is there any way to prevent them from going to other pages. In a fairly large code, an error occurs before the form submit and I can not catch it.

Answer 1

Open developer tools and put a break point in the submit function.

Answer 2

<form onsubmit='return false'>
Or after clicking on the submit button, as soon as you see that an error has occurred (it does not show the icon), press escape, the submit will stop =)
