本文实例讲述了javascript文件加载管理简单实现方法。分享给大家供大家参考。具体如下:

这里介绍超级简单的进行javascript的文件(模块)的加载管理,实现sea.js或者require.js核心功能,用一行<script src="js/light/light.js"></script>加载所有的js文件。好了,废话不多说,直接上码!

//按照lightJs的顺序,让网页加载js文件: 
var lightJs = ["./js/light/pre/jquery-1.8.0.min.js", "./js/light/pre/jquery-lib.js", "./js/light/pre/less-1.4.2.min.js", "./js/lihgt/pre/util.js", "./js/xla.js", "./js/light/light_file.js"];
var light;
if (!light) light = {};
light.load = (function(lightJs) {
if (!lightJs) lightJs = [];
var doc = document;
var head = doc.head || doc.getElementsByTagName("head")[0] || doc.documentElement;
for (var i = 0; i < lightJs.length; i++) {
var path = lightJs[i];
var node = doc.createElement("script");
node.charset = "utf-8";
node.src = path;
head.appendChild(node);
}
return doc;
} (lightJs));
