动态加载js和css的jquery plugin （Jquery插件）[转]

放在javascript文件头部，就像C#（using...）或Java（import ...）

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

调用方式

$.includePath = 'JS或者CSS的路径';$.include(['jquery.tree.js', 'jquery.tree.css']);
