jquery - get url path?
提问by KittyYoung
I know I can use window.location.pathname to return a url, but how do I parse the url?
我知道我可以使用 window.location.pathname 来返回一个 url，但是我如何解析这个 url？
I have a url like this: http://localhost/messages/mine/9889and I'm trying to check to see if "mine" exists in that url?
我有一个这样的网址：http://localhost/messages/mine/9889，我试图检查该网址中是否存在“我的”？
So, if "mine" is the second piece in that url, I want to write an if statement based on that...
因此，如果“我的”是该 url 中的第二部分，我想根据它编写一个 if 语句......
if(second argument == 'mine') { do something }

if ( location.pathname.split("/")[2] == "mine" ) { do something }
Although it would obviously be better to check whether there are enough items in the array that's returned by split:
尽管检查 split 返回的数组中是否有足够的项目显然会更好：
var a = location.pathname.split("/");
if ( a.length > 2 && a[2] == "mine" ) { do something }
Note that even though array indexes are zero based, we want to specify 2 as the index to get what you refer to as the 2nd argument as split splits "/messages/mine/9889" into an array of 4 items:
请注意，即使数组索引是从零开始的，我们也希望指定 2 作为索引以获得您所说的第二个参数，因为 split 将“/messages/mine/9889”拆分为 4 个项目的数组：
["", "messages", "mine", "9889"]

if jquery is an option, you could do the following:
如果 jquery 是一个选项，您可以执行以下操作：
$.inArray("mine", window.location.pathname.split("/"))
回答by Matt
if (window.location.pathname.split("/")[2] == "mine") {
// it exists
};
window.location.pathname is a string at the end of the day, so the usual string methodsapply.

Even though this is a very old query.. it pops up in some search. So to add my notes.. over here
尽管这是一个非常古老的查询......它会在某些搜索中弹出。所以添加我的笔记..在这里
url.indexOf('mine') !== -1
The above should be used for the check to find if url has a string... where as to find the path, it would be better off to use
上面应该用于检查以查找 url 是否有字符串......至于找到路径，最好使用
var a = document.createElement('a');
a.href = url;
console.log(a.pathname);
// if url='http://localhost/messages/mine/9889'
// output will be /messages/mine/9889hope this will save some ones time
希望这会节省一些时间

You could use the string.split('/') function to create an array of items to check otherwise there are several jQuery plugins that parse the url eg
您可以使用 string.split('/') 函数创建一个项目数组来检查，否则有几个 jQuery 插件可以解析 url，例如
