javascript tutorial - [Solved-5 Solutions] Set a javascript breakpoint in code-in chrome - javascript - java script - javascript array



Problem:

WE want to force the chrome debugger to break on a line via code, or else using some sort of comment tag such as something like console.break(). Is there a way to do this

Solution 1:

We can use debugger; within our code. If the developer console is open, execution will break. It works in firebug as well.

Solution 2:

As other have already said, debugger; is the way to go. WE wrote a small script that we can use from the command line in a browser to set and remove breakpoint right before function call:

Solution 3:

Set up a button click listener and call the debugger;

Example

$("#myBtn").click(function() {
 debugger;   
});

Solution 4:

We can also use debug(function), to break when function is called. Command Line APWE Reference: debug

Solution 5:

Breakpoint :- breakpoint will stop executing, and let we examine JavaScript values. After examining values, we can resume the execution of code (typically with a play button). Debugger :- The debugger; stops the execution of JavaScript, and callsthe debugging function. The debugger statement suspends execution, but it does not close any files or clear any variables.

Example:-
function checkBuggyStuff() {
  debugger; // do buggy stuff to examine.
};
