使用JavaScript自动为网址文本添加超链接
有些情况可能需要用到这个，例如网页里有大量链接，以文本形式存在。手动添加超链接显然不现实，这时可以用JavaScript配合正则匹配和replace()替换函数解决。将下面代码加至</body>前，绑定内容父标签ID名称即可使用，原生JS用法，不用加载jQuery库。
HTML
<div id="demo">包含网址的文本内容</div>
JavaScript
window.onload = function() {
var label = document.getElementById("demo");
var text = label.innerHTML;
var regular = /((https|http):\/\/[\w.\/\:\-]+)(?![^<]+>)/gi;
label.innerHTML = text.replace(regular, "<a href='$1' target='_blank'>$1</a>");
}
