jQuery从文本中提取URL [英] Jquery Extract URL from Text

问题描述

我需要使用jquery从文本中提取URL.

I need to extract URL from a text using jquery.

让我们说我在文本区域代码后面的页面上有

Lets say i have sowhere on the page following textarea code

<textarea rows="20" name="textarea" style="width:100%;">
   @techreport{blabl,  
   blabla = {},  
   url = {http://server.com/thepdf.pdf},  
   wrongurl ={http://server.com/thepdf2.pdf}, 
   blablabla = 1998,  
   blablablabla= {blablablablabla}}
</textarea>

我只需要url内容，而不是错误的URL.

i need the url, and only the url contents - not wrongurl.

更新:它始终具有相同的结构，我只需要一次提取它，并且它前面总是有一个"url = {".

Update: it has always the same structure and i only need to extract it ONCE and it always has an "url = {" in front of it.

推荐答案

如何解决

$(document).ready(function() {

    $('#click').click(function(){

 var one = document.getElementById('one');       
    one.value.match(/url ={([^}]*)}/,"");
    alert( RegExp.$1);


    })    
})

糟糕，游戏有点晚了，但修改了示例和jsfiddle，只显示了网址

oops, bit late to the game but ammended the example and the jsfiddle to only show the url
