Question

I have a form which is being submitted by ajax. Before submission, there’s a function which checks if a textarea in the form is empty before submitting. if it is empty, I need to stop the script and show a modal box AND prevent the submission of data to proceed.

How do I stop execution? Do I use

break;

?

Answer 1

Nope, you generally use return;

Of course the exact details will vary depending on your implementation. You may need to return false;, for instance, and manually check the return value to see whether or not to keep executing script in the calling function.
