Programmatically stop Javascript execution in FireFox/FireBug


I am currently debugging complex Javascript/AJAX code written with mootools with FireBug. I am looking for a way to stop the JS execution as if it was a breakpoint programmatically.



Ex:




instructions ...
degugger.breakpoint(); // the execution stops here as if a breakpoint was
// manually set
other instructions ...



any idea?

  1. In Firefox, IE, Safari and Chrome (not Opera) you can set the debugger directive.

    // your JS code
    ...
    // break here
    debugger;


    This is extremely useful with Firebug.

  2. you can debug using firebug
    just open the script tab and blick on the line where you want the execution to stop
