下面是密码框
<input name="usersInf.loginPass" id="upass" onkeyup="checklevel(this.value)" maxlength="18"
class="asiptinput" type="password" style="width:250px;"/>
<span class="datetime">
<span class="txtred"> * </span> 请输入6-18个字母、数字、下划线
<span id="pass1" class="txtred"></span>
<!-- <div id="pwdisok" style="display: none;width:330px;"> -->
<!-- 密码强弱判断 -->
<span id="pwd_small" class="w1"> </span>
<span id="pwd_center" class="w2"> </span>
<span id="pwd_ok" class="w3"> </span>
<!-- </div> -->
</span>
下面是密码框触发的函数，对输入的密码进行处理，区分开来是那个等级的，并显示
