这篇文章主要为大家展示了“如何使用js的闭包原理做对象封装及调用方法”，内容简而易懂，条理清晰，希望能够帮助大家解决疑惑，下面让小编带领大家一起研究并学习一下“如何使用js的闭包原理做对象封装及调用方法”这篇文章吧。
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。
