In IE, you can see a "Dynamic Script" folder at the bottom of the debugger's document list, where you can find dynamically loaded scripts, but ... A large number of, can not customize the name ...
But in Chrome, seemingly can't find the dynamic script, search the Web, found that can use //# sourceurl=xxx.js to customize the name of the dynamic script, very convenient!
<script> //# sourceurl=xxx.js / / other JS code ... </script>
You can also use the format //# sourceurl=http://abc.com/xxx.js to classify different dynamic scripts with domain names and paths!

According to the description of the official IE blog, in the latest IE, seems to have been able to use sourceURL comments, but the test, still no effect ... Or maybe I'm using the wrong method ... (Test IE version: 11.0.9600.17842)

The rest (Firefox?) Browser not tested ... Well, just went to test a bit, Firefox is also supported, no problem!
