如何打印所有来电者祖先

Question

I am tracing a bug in Javascript,

And want to know where is the original root cause,

But the function calls are too deep.

I use this way to find the first caller. arguments.callee.caller....

How to print all the callers in a time ?

Thanks

Either:

A) Insert a debugger; statement on its own line in your JavaScript (at a point where you'd like execution to pause). Open Chrome Dev Tools and reload your page.

Or:

B) Open Chrome Dev Tools, select the Sources panel, open the relevant (JS) file, click on a line number to add a breakpoint, and reload your page.

And then:

Inspect values by hovering over them in the upper Sources panel (and clicking the resultant popup to drill down into them) or by clicking them the Scope Variables and Watch Expressions panels on the lower-right.

While debugging, you can also insert further breakpoints (the blue pentagons), step into/through/over function calls, and run code-checks in the console.
