jQuery检测并验证URL

Question

我们假设我有这样的文字:

Hi, my name is Pablo and my home page is http://zad0xsis.net

如何检测并验证URL以便自动将其包装到<a href="the detected url">the detected url</a>？谢谢!

Answer 1

你可以使用正则表达式:

var s = 'Hi, my name is Pablo and my home page is http://zad0xsis.net';
var exp = /(\b(https?|ftp|file):\/\/[-A-Z0-9+&@#\/%?=~_|!:,.;]*[-A-Z0-9+&@#\/%=~_|])/ig;
s = s.replace(exp,"<a href=\"$1\">$1</a>"); 
alert(s);
