While using "XHR breakpoints" to identify which line is triggering an AJAX request, I noticed that the call stack only shows Angular.js library lines. This makes it difficult to pinpoint the exact line in my code that triggered the request. What steps should I take to address this issue?
Additional information:
It may be relevant to mention that the AJAX response returns an error due to a non-existing URL. Furthermore, setting Angular as a blackbox prevents the breakpoint from triggering.
Angular doesn't send the Ajax request right away. Instead, it waits until after the digest cycle is complete.
To identify the code responsible for triggering the request, you can intercept the $http.get method or any other method used for making requests.
debugCall($http, "get"); // place this to execute only once
function debugCall(object, methodName){
var originalMethod = object[methodName];
object[methodName] = function(){
debugger;
originalMethod.apply(this, arguments)
}
}
You can also examine the Angular call stack for clues. In a demo like this one, the top function in the call stack may be named eventHandler.
If you navigate to that specific call frame and run event.target.outerHTML in the console, you'll see
