How jquery dynamically loads js/css files

jqueryThe built-in getSrcript file can only dynamically load js code, but cannot load css. Later, I wrote a program that can load js and css.

Let’s first look at jquery itself The getSrcript file with

Method

$.getScript(url,callback)

Instance

var testVar = 'New JS loaded!';
alert(testVar); function newFun(dynParam) {
alert('You just passed '+dynParam+ ' as parameter.');
}

Dynamic call 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"');//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>

The above can only dynamically load js code, but cannot load css. Later, I wrote a program that can load js and css.

$.extend({
include
Path: '',
include: function(file)
{
var files = typeof file == "
string
" ? [file] : file;
for (var i = 0; i < files.length; i++)
{
var name = files[i].replace(/^s|s$/g, "");
var att = name.split(&#39;.&#39;);
var ext = att[att.length - 1].toLowerCase();
var isCSS = ext == "css";
var tag = isCSS ? "link" : "script";
var attr = isCSS ? " type=&#39;text/css&#39; rel=&#39;stylesheet&#39; " : " language=&#39;javascript&#39; type=&#39;text/javascript&#39; ";
var link = (isCSS ? "href" : "src") + "=&#39;" + $.includePath + name + "&#39;";
if ($(tag + "[" + link + "]").length == 0) 
document
.write("<" + tag + attr + link + "></" + tag + ">");
}
}
});
$.include(['hpbox.js','pop_win.css']);
