Getting Chrome's console.log to display the line that called a function

Question

Is there any way in the Chrome Console tab to display the address that called a function?

I have a function that's being called but I don't know where from. I know I could break and look at the Call Stack but I'd rather just display at each entry who called it:

functon select_el() {
console.log("select_el called by " + ?????);

    etc.
}

Thanks

I just want the number of the line where the function was called. — Steve, Jan 09 '14 at 20:18

I don't think you can do that with console.log(). Try with console.error() if you're fine with red output.

Red is ok, but what would I put in console.error(???) to display the caller's line number? – Steve Jan 11 '14 at 17:53
`console.error()` will print a call stack with source file and line number. Check the console and you should see it (at least in Chrome). – Daniel Lidström Jan 13 '14 at 07:40

The answer to this question might be what you are looking for.

It uses the trick of throwing an exception, then accessing the LineNumber property and printing it.
