先來(lái)看jquery自帶的getSrcript文件
方法
$.getScript(url,callback)
實(shí)例
復(fù)制代碼 代碼如下:
var testVar = 'New JS loaded!';
alert(testVar); function newFun(dynParam) {
alert('You just passed '+dynParam+ ' as parameter.');
}
動(dòng)態(tài)調(diào)用方法
復(fù)制代碼 代碼如下:
<script type="text/javascript" src="../jquery.js"></script>
<script type="text/javascript">
$(function()
{
$('#loadButton').click(function(){
$.getScript('new.js',function(){
newFun('"Checking new script"');//這個(gè)函數(shù)是在new.js里面的，當(dāng)點(diǎn)擊click后運(yùn)行這個(gè)函數(shù)
});
});
});
</script>
</head>
<body>
<button type="button" id="loadButton">Load</button>
上面的只能動(dòng)態(tài)加載js代碼，但不能加載css，后來(lái)自己寫(xiě)了一個(gè)可加載js與css的程序。
代碼如下
復(fù)制代碼 代碼如下:
$.extend({
includePath: '',
include: function(file)
{
var files = typeof file == "string" ? [file] : file;
for (var i = 0; i < files.length; i++)
{
var name = files[i].replace(/^s|s$/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']);
