<h2>使用方法</h2>
<p>第一步:需设定表单项数据类型</p>
<p style="padding:10px;border:2px dashed #ea0; background-color:#ffe;"><input type="text" name="name" <strong style="color:#f00;">dataType="chinese[2,8]"</strong> /></p>
<p>第二步:实例表单验证</p>
<p style="padding:10px;border:2px dashed #ea0; background-color:#ffe;"><script type="text/javascript"><strong style="color:#f00;">new ValidatorForm(表单对象);</strong> </script></p>
<h3>dataType可选参数</h3>
<table width="100%" border="0" cellspacing="0" cellpadding="0">
 <tr>
 <th colspan="3" style="text-align:left; background-color:#eee;">基础验证</th>
 </tr>
 <tr>
  <th>email</th>
  <td>Email地址</td>
  <td rowspan="11"><strong>均可配合中括号使用</strong>,例如<br />
  长度验证:chinese[1,10] 为限制只能输入1-10个全角字符,<strong>注:一个全角字符长度为2</strong><br />
  数字大小验证:number[18,26] 为限制只能输入18-26的数字<br />
  日期范围验证:date[1970-1-1,2012-12-12] 为限制1970-1-1至2012-12-12日期<br />
  <strong>上限及下限设定</strong><br />
  下限设定:chinese[1,] 至少输入1个或以上有效字符<br />上限设定:chinese[,6] 最多输入6个有效字符<br />number和date格式也类式</td>

 <tr>
  <th>password</th>
  <td>密码:4-20位字母数字或@!#$%^&*.~组合</td>
 </tr>
 <tr>
  <th>date</th>
  <td>日期</td>

 </tr>
 <tr>
  <th colspan="3" style="text-align:left; background-color:#eee;">其它验证</th>
 </tr>
 <tr>
  <th>Compare</th>
  <td colspan="2">值对比:格式“Compare[比较符比较对象,比较类型]”<br />
  比较符包括[>,>=,<,<=,!=,=]<br />
  比较对象为表单项name,当表单有同名name值多项时取第一项<br />
  比较类型可选值[text,number,date]分别为[字符比较,数字比较,日期比较],留空时对当前项值自动识别后对比<br />
  例如Compare[=password]</td>
 </tr>
 <tr>
  <th>exec</th>
  <td colspan="2">自定义函数:格式“exec[函数名]” <br />
  传入当前输入框对象,返回json格式“{stat:结果[true/false],msg:提示文本,msgCss:样式[className],inCss:输入框样式[className]}”,stat为验证结果是否正确为必须返回项,其它项留空使用默认设置[inCss暂时未使用]
