如何使用正则表达式和javascript对表单进行全面验证

使用时请将下面的javascript代码存到一个单一的js文件中。
1、表单要求

<form name="formname" onSubmit="return validateForm(this)"></form>

将对表单中的所有以下类型的域依次验证，所有验证是去除了前导和后缀空格的，要注意是区分大小写的。
2、空值验证
表单中任意域加上emptyInfo属性将对此域是否为空进行验证（可以和最大长度验证\一般验证方式同时使用）。
无此属性视为此域允许空值。
如：
3、最大长度验证（可以和空值验证、一般验证方式同时使用）：

或,<br/>3、一般验证方式(不对空值做验证）:<br/>如：<input type="text" validator="^(19|20)[0-9]{2}$" errorInfo="不正确的年份!" ><br/>4、标准验证(不与其它验证方式同时使用）：<br/>全部通过<input type="hidden">来实现，并且不需要name属性以免提交到服务器。<br/>4.1、合法日期验证：<br/></p><div class="code" style="position:relative; padding:0px; margin:0px;"><pre class='brush:php;toolbar:false;'><input type="text" name="yearfieldName" value="2004">注：这里也可以是<select name="yearfieldName"></select>，以下同 <input type="text" name="monthfieldName" value="02"> <input type="text" name="dayfieldName" value="03"> <input type="hidden" validatorType="DateGroup" year="yearfieldName" month="monthfieldName" day="dayfieldName" errorInfo="不正确的日期!"></pre><div class="contentsignin">登录后复制</div></div><p>yearfieldName、monthfieldName、dayfieldName分别为年月日字段，月和日可以是两位(MM)或一位格式(M)，<br/>此处不对每个字段分别检验(如果要检验，请在年月日三个域分别使用前面的一般验证方式），只对日期的最大值是否合法检查;<br/>4.2、日期格式验证(请注意，此验证不对日期是否有效进行验证，还未找到从格式中得到年月日数据的方法^_^)：<br/></p><div class="code" style="position:relative; padding:0px; margin:0px;"><pre class='brush:php;toolbar:false;'><input type="text" name="datefieldName" value="2003-01-03 21:31:00"> <input type="hidden" validatorType="Date" fieldName="datefieldName"; format="yyyy-MM-dd HH:mm:ss" errorInfo="不正确的日期!"></pre><div class="contentsignin">登录后复制</div></div><p>其中格式仅对y、M、d、H、m、s进行支持(其它字符视为非时间的字符)<br/>4.3、列表验证：<br/>检验列表(checkbox、redio、select)是否至少选中了一条记录(对select主要用于多项选择)<br/></p><div class="code" style="position:relative; padding:0px; margin:0px;"><pre class='brush:php;toolbar:false;'><input type="checkbox" name="checkbox1"> <input type="hidden" validatorType="Checkbox" fieldName="checkbox1" errorInfo="请至少选中一条记录!"></pre><div class="contentsignin">登录后复制</div></div><p>其中validatorType可以是Checkbox、R、Select;<br/>对于一个select表单，如果要求选择一条不能是第一条的记录，请用下列方式:<br/></p><div class="code" style="position:relative; padding:0px; margin:0px;"><pre class='brush:php;toolbar:false;'><select name="select1" emptyInfo="请选择一个选项!"> <option value="">==请选择==</option> <option value="1">1</option> <select></pre><div class="contentsignin">登录后复制</div></div><p>4.4、Email验证：<br/></p><div class="code" style="position:relative; padding:0px; margin:0px;"><pre class='brush:php;toolbar:false;'><input type="text" name="email"> <input type="hidden" fieldName="email" validatorType="Email" separator="," errorInfo="不正确的Email!"></pre><div class="contentsignin">登录后复制</div></div><p>其中separator为可选项，表示输入多个email时的分隔符(无此选项只能是一个地址）<br/>4.5、加入其它javascript操作：<br/></p><div class="code" style="position:relative; padding:0px; margin:0px;"><pre class='brush:php;toolbar:false;'><script type="text/javascript"> function functionname(){ 自定义方法 } </script> 表单中加入<input type="hidden" validatorType="javascript" functionName="functionname">（此时emptyInfo等属性无效） 时将调用function属性中指定的javascript方法（要求方法返回true或false，返回false将不再验证表单，也不提交表单)。 5、在表单通过验证提交前disable一个按钮（也可将其它域disable,不能与其它验证同在一个域)，不要求按钮是表单中的最后一个 <input type="button" name="提交" validatorType="disable"> 6、不验证表单 <input type="hidden" name="validate" value="0" functionName="functionname"> 当validator域值为0时不对表单进行验证，直接提交表单或执行指定function并返回true后提交表单 functionName为可选 --> <script type="text/javascript"> function getStringLength(str){ var endvalue=0;
