JavaScript-如何从文件名中分离路径

Question

I need to separate the file path from the file name: (some codes did not work in the past) If the path is www.example.com/hi/test/home.html How would I get just www.example.com/hi/test/ ?

Answer 1

You can use substring and lastIndexOf :

a = "www.example.com/hi/test/home.html";
b = a.substr(0, a.lastIndexOf('/'));

// b = www.example.com/hi/test
