A JavaScript tool that allows you to debug your JavaScript by giving you a stack trace of function calls leading to an error (or any condition you specify)

Just include stacktrace.js file on your page, and call it like so:

<scripttype="text/javascript" src="https://rawgithub.com/stacktracejs/stacktrace.js/master/stacktrace.js"></script><scripttype="text/javascript">// your code...vartrace=printStackTrace();alert(trace.join('\n\n'));// Output however you want!// more code of yours...</script>

You can also pass in your own Error to get a stacktrace not available in IE or Safari 5-

<scripttype="text/javascript" src="https://rawgithub.com/stacktracejs/stacktrace.js/master/stacktrace.js"></script><scripttype="text/javascript">try{// error producing code}catch(e){vartrace=printStackTrace({e: e});alert('Error!\n'+'Message: '+e.message+'\nStack trace:\n'+trace.join('\n'));// do something else with error}</script>

Note that error message is not included in stack trace.

Bookmarklet available on the project home page.

You can now have any (public or privileged) function give you a stacktrace when it is called:

functionlogStackTrace(stack){console.log(stack.join('\n'));}varp=newprintStackTrace.implementation();p.instrumentFunction(this,'baz',logStackTrace);functionfoo(){vara=1;bar();}functionbar(){baz();}foo();//Will log a stacktrace when 'baz()' is called containing 'foo()'!p.deinstrumentFunction(this,'baz');//Remove function instrumentation
