Question

I am looking to write a javascript function that will fire when a user submits a form, however I do not have edit access to the submit button so that I can add the onsubmit function. I am able to add a <script> tag, so if I can detect the submit, then I can execute my code. Anyone know how to do this?

Answer 1

You can locate the submit button through the DOM (getElementByID() or document.formname come to mind) and then set the submit button’s onsubmit value to a function of your choice.
