javascript line by line debugger

This might sound crazy but is there a debugger out there which automatically breaks on the first line of executed code ?

Sample : suppose I have debug mode on and I click on a button. Now the intelligent debugger should automatically set the breakpoint on the first line inside the .click({}) function.

This way it is very easy to see the starting point and very easy to backtrack.

There must surely be something.

Thanks

Chrome with CTRL+SHIFT+J. ;) You can put breakpoints there. I think it also works under FF. Also new versions of IE have JavaScript debuggers (don't remember the shortcut though).

F12 in most browser opens the debugger. Chrome, Safari, IE have this by default, and for FF there is the Firebug add on.

Also you can debug from visual studio, select debug from the menu --> Attach to process and then select the interter explorer process. But You should enable the script debuging in Internet Explorer first.

Most debuggers in the browser allow you to insert the keyword

debugger;

into your code which will cause a break to occur at that point in the execution.
