如何从URl获取特定文本 [英] How To Get Specific Text From URl

问题描述

Hello Coders ...



http://fayettevillenc.backpage.com/AutosForSale/2008-mercury-milan-i4-used-car-lot-nc/15472524 [ ^ ]





i希望从http到//获取内容。



like在上面的链接我想fayettevillenc ..



你能告诉我怎么做吗？

解决方案

< blockquote>如果你想获得构成完整路径的每个部分，

使用split函数拆分/并使用数组索引获取构成路径的目录的每个部分。 />


现在，如果你想获得查询字符串，

例如www.yourdomain.com/test.aspx?id=1&lang=net& ; category = mvc



哟你可以在javascript中使用一个简单的函数

< br /> 
函数queryString（name）{< br /> 
 var match = RegExp（'[？&]'+ name +'=（[^&] *）'）< br /> 
 .exec（window.location.search）; < br /> 
返回匹配&& decodeURIComponent（匹配[1] .replace（/ \ + / g，''））;< br /> 
}< br /> 

用javascript访问查询字符串

< br /> 
 var id = queryString（'id'）;< ; br /> 
 var lang = queryString（'lang'）;< br /> 

如果你想在客户端的PHP bot中做，你可以使用

PHP拆分功能

Hello Coders ...

解决方案

If you want to get each part that forms a full path,
use split function to split "/" and use the array index to get each part of the directory that forms a path.

Now, if you want to get the querystring,
e.g www.yourdomain.com/test.aspx?id=1&lang=net&category=mvc

You can use a simple function in javascript

<br />
function queryString(name) {<br />
    var match = RegExp('[?&]' + name + '=([^&]*)')<br />
                    .exec(window.location.search);<br />
    return match && decodeURIComponent(match[1].replace(/\+/g, ' '));<br />
}<br />

to access the query string in javascript

<br />
var id = queryString('id');<br />
var lang = queryString('lang');<br />

If you want to do it in PHP bot in client side, you can use
PHP split function
