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.'); }
<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>
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']);
