Chrome，Safari和其他基于WebKit的浏览器在Web检查器中包含一项称为实时编辑的功能。如果您转到脚本面板并在断点处停止（或者即使没有在断点处停止-我不确定），则可以双击一行并开始编辑该行。您所做的更改将在脚本上生效。

Chrome, Safari, and some other WebKit-based browsers contain a feature in the Web Inspector known as Live Edit. If you go to the Scripts panel and are stopped on a breakpoint (or maybe even if not stopped on a breakpoint — I'm not sure), you can double click on a line and start editing that line. The changes you make will take effect on the script.
