简单的js模块加载
var check = {} require = function(name, callback){ //name切割成多个模块名,然后转换为URL //for循环 //这里会运行于iframe中 var s = document.createElement("script") document.body.appendChild(s) s.src = name //for循环结束 check[name] = callback //以后check[name]会对应一个对象 } //这是执行回调 require.exec = function(factory, name, list){ var ret = factory.apply(null, list || []) check[name](ret) } //这是模块用到define方法 define = function(name, callback, list){ //这大大被简化了,还要从URL还原name,处理依赖列表 var str = "require.exec(" + callback.toString() +",'"+name +"')" var s = document.createElement("script") document.body.appendChild(s) s.text = str; }
