$.extend({
includePath: '',
include: function(file) {
var files = typeof file == "string" ? [file]:file
for (var i = 0i <files.lengthi++) {
var name = files[i].replace(/^\s|\s$/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 + ">")
}
}
})
二、使用方法：
$.include('dedeajax.js')
$.include('android.css')
或者：
$.includePath='www/html/'
$.include([dedeajax.js','android.css'])
用JQ自带的AJAX来动态加载你想要的JS文件
$.getScript("这是你的JS名字.js", function(){alert("这是JS加载完了成功的回调函数")
})
这是动态加载的JS文件，ajax必须要有环境才能运行
<!DOCTYPE html><html>
<head>
<meta charset="utf-8">
<title>动态引入jQuery</title>
<style>
*{ padding:0margin:0font-size:14px }
</style>
</head>
<body>
<p>1</p>
</body>
<script type="text/javascript">
var script = document.createElement('script')
script.setAttribute("type", "text/javascript")
script.setAttribute("src", 'http://code.jquery.com/jquery-1.9.1.js')
document.head.appendChild(script)
// 由于是动态引入的，需要做个延时，不然页面是还没有加载jQuery文件的
setTimeout(function(){
$(function(){
$('p').text('aaaaaaaaaaaaa')
})
},5)
</script>
</html>
