一段基于jQuery的，验证用户密码的简单应用2

<form id="pw">   ORIGINAL PASSWORD:<input type="text"  id="pw0"/>   <br><br>   NEW PASSWORD:<input type="text"  id="pw1"/>   <br><br>   REPEAT PASSWORD:<input type="text" id="pw2"/>   <br><br>   <input type="submit" value="submit"/>   </form>    此篇文章仍为原创，上一次的密码验证在使用中出现了不少问题，所以进行了重写，这回的代码和上次相比略有清爽感，绝的作为程序员代码重构还是很重要的，希望能有读者给予评论，哈哈。
