jquery動態載入js/css檔案方法

來源:互聯網

先來看jquery內建的getSrcript檔案

方法

 代碼如下 複製代碼

$.getScript(url,callback)

執行個體

 代碼如下 複製代碼

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

動態調用方法

HTML代碼

 代碼如下 複製代碼

<script type="text/javascript" src="../jquery.js"></script> 

<script type="text/javascript"> 

$(function()

{

$('#loadButton').click(function(){

$.getScript('new.js',function(){

newFun('"Checking new script"');//這個函數是在new.js裡面的,當點擊click後運行這個函數

});

});

});

</script> 

</head> 

<body> 

<button type="button" id="loadButton">Load</button> 

上面的只能動態載入js代碼,但不能載入css,後來自己寫了一個可載入js與css的程式。

 代碼如下 複製代碼

$.extend({
    includePath: '',
    include: function(file)
    {
        var files = typeof file == "string" ? [file] : file;
        for (var i = 0; i < files.length; i++)
        {
            var name = files[i].replace(/^s|s$/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']);
