利用js的闭包原理做对象封装及调用方法

创建一个js文件，名为testclosure.js：

(function () {
  function a()
  {
    alert('i am a');
  }
  outfunc = function () {
    a();
  }
})();

这里不论写多少个function,a b c d ...外面都调用不到，包括这里面var定义的变量也都调用不到，那么你在里面尽情的写，就不用担心这些函数名变量名跟外界冲突；

只需要暴露一个outfunc这个函数供外界调用。这个函数呢没有用var定义，就变成一个全局变量，外界就可以调用的到，利用这一点，让这个函数变成匿名函数和外界沟通的桥梁。

再利用js面向对象的方法，就可以封装出非常好用的组件。
