Javascript backtrace

问题

How to I get a backtrace in Javascript?

Ideal features:

• entry function name, or some meaningful identifier for anonymous functions,
• argument list at each level,
• line numbers.

Can this be done in standard ECMAScript?

If not, can it be done in the common web browser dialects?

Thanks.

Edit --

Thanks for your suggestions.

My dialect doesnot support arguments.caller or arguments.callee.

I can do this:

try {
    let x = null;
    x .foo ();
}
catch (e) {
        debug (dump (e.stack));
}

Which gets me the information as a string, which is okay for at-a-glance, but it would be a great help to walk e.stack. Does it have a standard form?

Thanks again.

How do you find out the caller function in JavaScript?

回答2:

In my debugging experience, I always use this

(function () { console.log(new Error().stack); })();

As the comments below suggested, the readers should prefer: console.log(new Error().stack);

This lib: stacktrace-js works anywhere, not only with errors.

Example:

StackTrace.get()
    .then(stack => { console.log(stack) })
    .catch(err => { console.log(err) });
