Javascript：在使用IE进行调试时，“源代码不适用于此位置”msg

Question

I am trying to debug some issue using IE 8 developer tools.

However after running the below code, the debugger throws error "Source Code not available for this location"

 window.onload = function() {
  tabberAutomatic(tabberArgs);
};

What does it mean ?

Above code is part of below code which basically runs the function tabberAutomatic once the document has finished loading:

/* This function adds tabberAutomatic to the window.onload event,
     so it will run after the document has finished loading.
  */
  var oldOnLoad;

  if (!tabberArgs) { tabberArgs = {}; }

  /* Taken from: http://simon.incutio.com/archive/2004/05/26/addLoadEvent */

  oldOnLoad = window.onload;
  if (typeof window.onload != 'function') {
    window.onload = function() {
      tabberAutomatic(tabberArgs);
    };
  } else {
    window.onload = function() {
      oldOnLoad();
      tabberAutomatic(tabberArgs);
    };
  }

I am trying to debug issue explained in my previous question browser showing progress bar as still progressing even when the page is loaded

Thanks for inputs!!

Are you looking at the right file in the debugger?
