看过goole closure 的同学都知道 其中定义一个类名函数时候只要 inlude("") 想加载某个模块只要require("")就可以利用：
下面给出一个例子：
<!DOCTYPE html>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8">
<title>分模块加载</title>
<style>
</style>
</head>
<body>
<script>
//*********定义加载模块方法 start **************//
(function (window, undefined) {
if (window.define) {
return
}
function isFunction(obj) {
return Object.prototype.toString.call(obj) === "[object Function]"
}
var MM = {};
var initModuleName = "initRun";
function require(name) {
if (!MM[name]) {
throw new Error("Module " + name + " is not defined.")
}
var module = MM[name];
if (module.inited === false) {
runModule(name)
}
return module.ret
}
function runModule(name) {
var exports = {};
var module = MM[name];
if (isFunction(MM[name].factory)) {
var ret = MM[name].factory.apply(undefined, [require, exports, undefined]);
module.ret = ret === undefined ? exports : ret
} else {
module.ret = MM[name].factory
}
module.inited = true
}
function define(name, deps, factory) {
if (MM[name]) {
throw new Error("Module " + name + " has been defined already.")
}
if (isFunction(deps)) {
factory = deps
}
MM[name] = {factory:factory, inited:false};
if (name === initModuleName) {
runModule(name)
}
}
window.define = define
})(window);
//*********定义加载模块方法 end **************//
//下面给一个使用的例子
(function(){
define('View/test',function(require){
var testObj = function(){};
testObj.prototype = {
test : function(){
alert("我是小测试");
}
};
return testObj;
});
//上面定义了当模块为initRun时候启动模块
define('initRun',function(require){
var test = require('View/test') ;
var testObj = new test;
testObj.test();
})
})()
</script>
</body>
</html>
