做一个弹框玩玩，顺便熟悉最近新学习的插件封装技术

先上图，没图不成席

【原因】由于公司从开发到现在时间都比较紧张，很多时候需要弹框的地方都直接用alert()、confirm()、prompt()这些自带的提示框，最大的问题是这三个哥们随着浏览器的不同进行变色，简直是前端变色龙，神奇又无奈

所以，这次和我们的帅气设计师合作总结出这三种提示框，我也通过最近的学习把新学到手的封装技术，融入了进去，相对于大神级别的人，看看就行，顺便指点一下就更好了

【目前自己思考的问题】到目前为止，自己工作也有2.5年了，早早过了只知道实现需求的时候了，更多的是培养自己大神级别的思想，和代码利用率等问题，路漫漫其修远兮，吾将上下而求索

【废话完事，来代码】

【理解】参数说明在代码注释部分，写的非常清楚，这里说说【alertBox.fadeIn(); //在固定的位置直接使用】，弹框一般会放在页面触发函数中，所以直接执行弹框弹出，这个根据自己需求来引用就可以了；

【注】这个小插件是基于jquery的，要是喜欢js的也可以改改
