如何使调试器可以访问已评估的javascript代码？

Question

I just spent a long time trying to figure out how to use source maps to get eval'd javascript code to show up in the debugger where I could put break points on it and stuff. I kept seeing hints that it was possible, but most of what I read had to do with source mapping minified code or CoffeeScript, and generally it all seemed impossibly complicated. But then I stumbled on the answer, which was ridiculously easy, and I'll answer my own question below.

Answer 1

Just put this at the end of the eval block:

//@ sourceURL=foo.js

In the Chrome sources panel, foo.js now shows up under '(no domain)'.
