解析文本格式與內容的網址，並縮短網址

Question

我想下面的文本解析成格式化的URL與錨標記：

something is wrong with http://www.gbin1.com/index.html, but cannot find the reason in http://www.google.com 

我怎麼能代替上面<a href="url">url</a>文字的網址，並使用縮短JavaScript如下所示：

something is wrong with <a href="http://www.gbin1.com/index.html">gbin1.com</a>, but cannot find the reason in <a href="http://www.gbin1.com">google.com</a>

檢查此解決方案。

var x = "something is wrong with http://www.gbin1.com/index.html, but cannot find the reason in http://www.google.com"; 
var expression = /[-a-zA-Z0-9@:%_\+.~#?&//=]{2,256}\.[a-z]{2,4}\b(\/[-a-zA-Z0-9@:%_\+.~#?&//=]*)?/gi; 
var regex = new RegExp(expression); 
var split = x.split(" "); 
for(var i=0; i< split.length; i++){ 
    if(split[i].match(regex)){ 
     var text = split[i].split(".").slice(1).join(".").split("/")[0]; 

     split[i] = '<a href=\"' +split[i]+'\">'+text+'</a>'; 
    } 
} 
console.log(split.join(" "));
