How do i work around Slash in Chrome extension?

In my extension i want to get href property of a object, which is /photo123456789_987654321.

But instead i get chrome开发者_运维百科-extension://extension-id/photo123456789_987654321.

How do i work around this?

Instead of using a more-complicated regex you can just use the first part of the string:

http://jsfiddle.net/3qRQT/

var someString = "chrome-extension://extension-id/photo123456789_987654321";

someString.replace("chrome-extension://extension-id","");

What about replacing the extension id with a regexp:

href_string.replace(/^chrome-extension:\/\/.*?\//, "/");

E.g.

var href_string = "chrome-extension://extension-id/photo123456789_987654321";
href_string.replace(/^chrome-extension:\/\/.*?\//, "/");

// "/photo123456789_987654321"
