How do I "step over" jQuery code while debugging?

Question

While stepping through a script that uses jQuery, I just want to test the code I wrote. I don't want to step into the jQuery file -- I'm not debugging jQuery, just my own file.

Are there any ways to tell a debugger to not step into the jQuery file? I use Visual Studio + Internet Explorer, as well as Firefox + Firebug for stepping through code ... and both seem to love to step through dozens of jQuery statements.

For example, say I have a script like this:

$("div").each(function() {
   $(this).hide();
});

This is technically a single statement -- therefore "Step Over" will execute all code at once, which will skip over the inner "hide" statement. However, "Step Into" will take me to the jQuery code, and I will have to step dozens of lines of code before it takes me to the "hide" statement.

I would like to have the debugger completely ignore the jQuery code, so I can easily step through just my own code and never step through the jQuery code.

In C#, this is possible by using the [DebuggerStepThrough()] attribute on a class. But that doesn't help with JavaScript.

Answer 1

At least firebug's javascript debugger has an option to "step over" which sill not descend into function calls. However, you will have to choose between "step (into)" and "step over" manually depending on what kind of function is called.

Answer 2

F10 should step over the function calls, F11 should step into the function calls. This works in VS as well as firebug.

Answer 3

Pretty sure the answer is "no, this feature does not exist".

What's your motivation here, though? It looks to me like setting a breakpoint on Line 2 and creating a watch for the "resultset" of Line 1 whilst you're there will get you what you're likely to want.

Answer 4

The answer is rather simple, you just have to refactor the function out. I can't recall

$("div").each(function() {
   doThis(this);
});

function doThis(object) {
   $(this).hide();
}

Will almost certainly work with a halfway decent debugger.
