您可以使用正则表达式在/ community / p>

  var url =http://www.example.com/community/whatever; 
 var category =; 
 var matches = url.match（/ \ / community\ /(.*)$/）; 
 if（matches）{
 category = matches [1]; //whatever
}

如果你想要在社区之后获得下一个路径段，并且在该段之后没有任何内容，那么您可以使用以下代码：

  var url = http://www.example.com/community/whatever/more; 
 var category =; 
 var matches = url.match（/ \ / community\ /（[^ \ /] +）/）; 
 if（matches）{
 category = matches [1]; //whatever
} else {
 //不匹配类别
}

I need to parse long urls and set a variable (category) equal to one of the /folders/ in the path.

For example, a url that is

http://example.com/community/home/whatever.html

I need to set the variable equal to whatever folder path comes after /home/ in that url.

I've got this to alert me with what comes after /community/, but then the url turns to NaN and the link doesnt work. I think I'm not on the right track.

if ($(this.href*='http://example.com/community/')){

  var category = url.split("community/");

  alert(category[category.length - 1]);

}

Thoughts?

TIA.

You can fetch everything after the "/community/" with a regular expression:

var url = "http://www.example.com/community/whatever";
var category = "";
var matches = url.match(/\/community\/(.*)$/);
if (matches) {
    category = matches[1];   // "whatever"
}

If you want to get only the next path segment after community and nothing after that segment, then you could use this:

var url = "http://www.example.com/community/whatever/more";
var category = "";
var matches = url.match(/\/community\/([^\/]+)/);
if (matches) {
    category = matches[1];    // "whatever"
} else {
    // no match for the category
}
