浏览器控制台里的$、$$是咋回事

程Hao同学提到:
浏览器的控制台里,可以直接使用$、$$方法,可是这些方法,却不能被页面里的JS使用。

赵WenBo同学给出解答:

https://developers.google.com/web/tools/chrome-devtools/console/utilities   
https://developer.mozilla.org/en-US/docs/Tools/Web_Console/The_command_line_interpreter#Helper_commands

谷歌的说明:

The Console Utilities API contains a collection of convenience functions for performing common tasks: selecting and inspecting DOM elements, displaying data in readable format, stopping and starting the profiler, and monitoring DOM events.

Warning: These functions only work when you call them from the Chrome DevTools Console. They won't work if you try to call them in your scripts.

点赞一下IE的某些版本,还可以直接看到函数体:
