Is there a way to find out which Javascript function is fired by click on a certain button?
Let me explain …
I have a web page with a large js script (not made by me), I’ve to detect which function is triggered by a specific button, I need to find the function triggered by this button.
Use Chrome’s Web Inspector to inspect the element and check out the Event Listeners panel.
If the code attaching the event is in a library (for example, by Zepto in my example), set a breakpoint on the line and examine the call stack to see where it originated in your code.
As you can see, the event has originated in my code and now I know the filename and line number.
