A small error-web-File System Path settings

This small error affects me for four hours.

In eclipse, when I set the file path, I mistakenly thought that the file itself is also a path. Therefore, in order to read the content in the folder under the same directory as it, I used the parent directory. But in fact, the file path is the folder where it is located. Therefore, to read the content in this folder, you need to use the current path.

 

In fact, this problem is easy to solve, but why does it take me so much time? The main reason is that you are not familiar with JavaScript debugging. Because I copy other people'sCodeBut they cannot see their file structure.Source codeI can't see a lot of clues (in fact, I can also see it carefully ). It was later debugged through firebug (firebug is really a good thing ). ThereforeProgramWhen debugging, it is best to use firebug :)
