How to find out the piece of code that initiated ajax request

Question

Answer 1

Another very good option in chrome developer tools is XHR Breakpoint. Press F12, Select the sources tab and on the right had side under XHR Breakpoint add a new conditional breakpoint condition by specifying the text you expect to find in the URL on which the ajax call is being made. It will stop on any ajax call which contains the text specified in the URL. You can give it a try on this URL (look for the heading Breakpoints on XHR)
