js的简略串行加载方案

js的简单串行加载方案
写了一个超简单的串行加载工具, 不想引入框架时, 可以试用下

(function (all) {var callee = arguments.callee;all.shift()(function(data) {callee.call(null, all, data);});})([function(next) {setTimeout(function() {document.body.innerHTML += '<li>first';next();}, 1000)}, function(next) {setTimeout(function() {document.body.innerHTML += '<li>second';next();}, 2000)}, function(next) {setTimeout(function() {document.body.innerHTML += '<li>third';}, 3000)}]);
