jQuery解析我们的一部分url路径 [英] jQuery to parse our a part of a url path

问题描述

我需要解析长url，并设置一个变量（类别）等于路径中 / folders / 之一。

例如，一个网址是

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

我需要设置变量等于任何文件夹路径出现在 / home / 在这个网址中。

我已经知道/ community /后面会出现什么内容，但是网址转换为NaN并且链接不起作用。我认为我没有走上正轨。

  if（$（this.href * ='http：// example .com / community /'））{
 
 var category = url.split（community /）; 
 
 alert（category [category.length  -  1]）; 
 
 
  

想法？

TIA。

解决方案

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.

解决方案

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"
}

Working example here: http://jsfiddle.net/jfriend00/BL4jm/

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
}
