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.'); }
动态调用方法
<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>
上面的只能动态加载js代码,但不能加载css,后来自己写了一个可加载js与css的程序。
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']);
jquery动态加载js/css文件方法(自写小函数)
