jquery动态加载js/css文件方法(自写小函数)

先来看jquery自带的getSrcript文件

方法

$.getScript(url,callback)

实例


var testVar = 'New JS loaded!';

alert(testVar); function newFun(dynParam) {

alert('You just passed '+dynParam+ ' as parameter.');

}


动态调用方法


<script type="text/javascript" src="../jquery.js"></script>

<script type="text/javascript">

$(function()

{

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

$.getScript('new.js',function(){

newFun('"Checking new script"');//这个函数是在new.js里面的,当点击click后运行这个函数

});

});

});

</script>

</head>

<body>

<button type="button" id="loadButton">Load</button>


上面的只能动态加载js代码,但不能加载css,后来自己写了一个可加载js与css的程序。

代码如下


$.extend({

includePath: '',

include: function(file)

{

var files = typeof file == "string" ? [file] : file;

for (var i = 0; i < files.length; i++)

{

var name = files[i].replace(/^s|s$/g, "");

var att = name.split('.');

var ext = att[att.length - 1].toLowerCase();

var isCSS = ext == "css";

var tag = isCSS ? "link" : "script";

var attr = isCSS ? " type='text/css' rel='stylesheet' " : " language='javascript' type='text/javascript' ";

var link = (isCSS ? "href" : "src") + "='" + $.includePath + name + "'";

if ($(tag + "[" + link + "]").length == 0) document.write("<" + tag + attr + link + "></" + tag + ">");

}

}

});

$.include(['hdivbox.js','pop_win.css']);
