I do not know what to press the shortcut keys, leading to somehow use Notepad to open the js file when you click on a method call in a js file, I tried several times like this when developing. Simply turn off reopen the js file, double-click the file or the result of a pop-up notepad, ~ ~ ~ wow, good weird ah!
