正则表达式并切断url的第一部分（bootstrap活动类从navbar元素中删除）

Question

I need some regex action. It should cut off the ip part and look for the string after the "/".

 $(function() {
     var url = document.URL.match(""); /* your awesome  regex here! */
     switch(url) {
         case "/Kalender":
             $('.cal').addClass("active");
             break;
         case "/Klienten":
             $('#asdf').addClass("active");
             break;
         case "/Aufgaben":
             $('.aufgaben').addClass("active");
             break;
         case "/Verwaltung":
             $('#verwaltung').addClass("active");
             break;
         case "/Willkommen":
             $('.nav > li:nth-child(1)').addClass("active");
             break;
         default:
             $('.nav > .active').removeClass();
             break;
     }
 });

Thank you for your time. Notes: I have changed the title of the question, now people who got the same problem can copy/paste this code.

regex:

[^/]*/(.*)

[^/] means NOT SLASH, * means 0 or more times The ( ) then capture what you want. On the inside of the ( ) is . which means ANYTHING.

finally, if you are using / as your regex delimiter, you will have to escape the slashes:

/[^\/]*\/(.*)/

So the exact code you need to add is

url = url.replace(/[^\/]/,"")

This finds all the "not slashes" until it runs into a slash. All that found stuff is replaced with "" (nothing).

You don't need regular expressions, just create an anchor linking the url, and get its pathName :

var a = document.createElement('a')
a.href = url;
a.pathName;

Or, in your case, if you want the path name of the current url, just use

location.pathname

The full code is

var selector = {
    "/Kalender": '.cal',
    "/Klienten": '#asdf',
    "/Aufgaben": '.aufgaben',
    "/Verwaltung": '#verwaltung',
    "/Willkommen": '.nav > li:nth-child(1)'
}[location.pathname];
$(selector || '.nav > .active').toggleClass("active", !!selector);

Answer 3

For completeness here is the code which parses the first string after a the "/".

var url = window.location.pathname.split("/");
console.log(url[1]);
