正则表达式匹配任何字符串，最多为“/”Javascript

Question

I have a Javascript function that loops through href navigation and matches it to the url location. If the two match then an "active" class is added. This works great, except for when someone goes to a page like "services/service1". How would I add the logic to look a string like "services/service1" or "blog/post1" and trim to just "services/" and "blog/"?

Here is my current function

scope.$on("$routeChangeSuccess", function (event, current, previous) {
        var location       = current.$$route.originalPath;
        var selectionhref  = element.children().find('a');
        //Searches for match of routepath url and href, removes siblings active, adds active
        (function(){ 
          element.children().each(function(index){
          console.log(location);  
          if($(selectionhref[index]).attr('href') == location){
          $(this).siblings().removeClass('active');  
           $(this).addClass('active');
          };
          });
        })()
      }); //routeChangeSuccess

没有RE或Split简单方法;

var root = location.substr(0, (location + "/").indexOf("/") + 1);

Answer 2

Use the replace function. It accepts a variety of params, one being a regular expression and the replacement string.

> "services/service1".replace(/[^\/]+$/, "")
'services/'

[^\\/]+ matches any character but not a forward slash / one or more times. $ asserts that we are at the end of a line.
