tips 移入悬浮功能

前景：

页面部分区域需要移入悬浮效果，当然默认的 title 也是可以的，最多只是格格不入，但是却是最为靠谱的。。

思路：

基于 jq 实例扩展、使用立即执行函数保持功能独立、自定义类实现功能封装的定位解释小功能

实现：

1.html

<!DOCTYPE html>

<html>

<head>

  <meta charset="UTF-8" />

  <title>tip</title>

  <link rel="stylesheet" href="tip.css" />

  <link rel="stylesheet" href="animate.css" />

</head>

<body>

  <div id="left" class="test left" data-mess="top title <br /> some mes ">left</div>

  <script src="https://blog-static.cnblogs.com/files/justSmile2/jquery-1.9.1.min.js"></script>

  <script src="tip.js"></script>

  <script type="text/javascript">

    $("#left").tips({

      "posType": "right"

    });

  </script>
