Let's start with jquery's built-in getSrcript files

methods

$. GetScript (url, callback)

The instance



var testVar = 'New JS loaded!';

alert(testVar); function newFun(dynParam) {

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

}

Dynamic invocation method



<script type="text/javascript" src="../jquery.js"></script>
<script type="text/javascript">
$(function()
{
$('#loadButton').click(function(){
$.getScript('new.js',function(){
newFun('"Checking new script"');//This function is inside new.js and runs when you click click
});
});
});
</script>
</head>
<body>
<button type="button" id="loadButton">Load</button>

The above can only dynamically load js code, but can not load CSS, later I wrote a load js and CSS procedures.

The following code



$.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']);
