一個簡單的動態載入js和css的jquery程式碼，用於在產生頁面時透過js函數載入一些共通的js和css檔案。
//how to use the function below:
//$.include('file/ajaxa.js');$.include('file/ajaxa.css');
//or $.includePath = 'file/';$.include(['ajaxa.js','ajaxa.css']);(only if .js and .css files are in the same directory)
$.extend({
includePath: '',
include: function(file)
{
var files = typeof file == "string" ? [file] : file;
for (var i = 0; i < files.length; i++)
{
var name = files[i].replace(/^\s|\s$/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' " : " type='text/javascript' ";
var link = (isCSS ? "href" : "src") + "='" + $.includePath + name + "'";
if ($(tag + "[" + link + "]").length == 0) $("head").prepend("<" + tag + attr + link + "></" + tag + ">");
}
}
});
$.include('../js/jquery-ui-1.8.21.custom.min.js');
$.include('../css/black-tie/jquery-ui-1.8.21.custom.css');將該函數寫入一個common.js檔案中，在html中載入該common.js文件，就可以達到目的。
注意：
1.在html5中，
