   * <b>简介</b><br/>
   * validate() 可以方便地对Html Form进行校验. 
   * </div>
   * <div>
   *  <pre>
   * 1、本校验框架提供了丰富的校验规则，满足常用的校验需求。
   *    内置的校验规则有
   <table border="1">
    <tr>
      <td align="center" style="font-weight: bolder;">rule名称</td>
      <td align="center" style="font-weight: bolder;">说明</td>
      <td align="center" style="font-weight: bolder;">默认提示</td>
    </tr>
    <tr>
      <td>required</td>
      <td>值必须输入</td>
      <td>This field is required.</td>
    </tr>
    <tr>
      <td>min</td>
      <td>能输入的最小值</td>
      <td>$.validator.format("Please enter a value greater than or equal to {0}.")</td>
    </tr>
    <tr>
      <td>max</td>
      <td>能输入的最大值</td>
      <td>$.validator.format("Please enter a value less than or equal to {0}."),</td>
    </tr>
    <tr>
      <td>minlength</td>
      <td>必须输入minlength长度的字符</td>
      <td>$.validator.format("Please enter at least {0} characters.")</td>
    </tr>
    <tr>
      <td>maxlength</td>
      <td>最多能输入maxlength长度的字符</td>
      <td>$.validator.format("Please enter no more than {0} characters.")</td>
    </tr>
    <tr>
      <td>email</td>
      <td>邮件格式</td>
      <td>Please enter a valid email address.</td>
    </tr>
    <tr>
      <td>url</td>
      <td>url地址格式</td>
      <td>Please enter a valid URL.</td>
    </tr>
    <tr>
      <td>date</td>
      <td>日期格式</td>
      <td>Please enter a valid date.</td>
    </tr>
    <tr>
      <td>number</td>
      <td>数字格式</td>
      <td>Please enter a valid number.</td>
    </tr>
    <tr>
      <td>rangelength</td>
      <td>输入字符长度在某一个范围，有两个参数传入</td>
      <td>$.validator.format("Please enter a value between {0} and {1} characters long.")</td>
    </tr>
    <tr>
      <td>accept</td>
      <td>可以接受的文件格式</td>
      <td>Please enter a value with a valid extension.</td>
    </tr>
    <tr>
      <td>equalTo</td>
      <td>和已经有的属性做对比（适合重输密码）</td>
      <td>Please enter the same value again.</td>
    </tr>
    <tr>
      <td>range</td>
      <td>输入的数值必须在某一个范围，传入两个参数</td>
      <td>$.validator.format("Please enter a value between {0} and {1}.")</td>
    </tr>
    <tr>
      <td>digits</td>
      <td>必须输入数字</td>
      <td>Please enter only digits.</td>
    </tr>
  </table>
   *    
   * 2、提供灵活的校验信息展现风格，你可以让信息展现在校验元素尾部，也可以让它展现在你想要的任何div里面，
   *    对于空间比较吃紧的form表单，也可以采用鼠标移动到提示图标悬浮显示提示信息的方式。这些主要通过配置
   *    errorPlacement(定制错误信息显示)、showErrors(自定义消息处理，onblur/keyup触发，针对当前元素)
   *    只要你够强大，它就有多强大。
   *  
   * 3、提供了灵活的接口用于增加校验规则，当我们提供的校验规则不能满足您的需求的时候，你可以自定义校验
   *    规则，通过$.validator.addMethod("hasreg", function(value,element,params) {return true/false;},"message")的方式实现
   *   </pre>
   * </div>
   * <b>如何使用</b><br/>
   * 1、基本结构
   *    <pre>
   *      $("#reg").validate({
   *         onkeyup : true,
   *         rules : {
   *           password : {
                          required : true,
                          minlength : 5
               }
   *         },
   *         messages : {
   *           password : {
                          required : '密码必须输入',
                          minlength : '密码不能小于5位'
               }
   *         }
   *      });
   *     
   *    上面就是基本的校验结构，reg是需要校验的form的id，password是需要校验的字段的name
   *    (<span style="color:red;">必须配置name，否则将不能校验</span>)rules和messages是成对出现的，如果只配置了rules没有配置messages，
   *    系统将使用默认提示信息。
   * 2、自定义校验规则
   *      $.validator.addMethod("hasreg", function(value) {
   *              return value != 'admin';
   *       }, '此用户已经被注册');
   *       //模拟用户名是否已经被注册，真实的场景应该是使用ajax向后台发送请求，然后后台返回结果，
   *       //需要注意的是必须使用同步请求，异步请求将无效。
   *    
   *    现在就已经有了一个新的rules “hasreg”，它的使用同系统内置的规则一样，在需要校验
   *    的字段里面配置hasreg:true，因为messages已经配置，故可以不写。
   * 3、自定义信息展示
   *    框架默认的是在内容后面增加一个&lt;label for="username" generated="true" class="error"&gt;请输入用
   *    户名&lt;/label&gt;，同时在校验的元素上面增加class="error"属性，如果你想要一些效果，请编写error样式。
   *    如果这种提示方式不是你想要的，或者你不希望它来包装你的提示信息，你需要用到两个方法
   *    errorPlacement、showErrors鉴于这两个方法的复杂性和强自定义性，下面对他们做一个详细的说明。
   *    1)、errorPlacement
   *        错误信息展示，有两个参数error和element，error是生成的错误对象；element为当前元素。
   *        errorPlacement : function(error, element) { 
   *                   if(error){    //error存在的时候
   *                       $('#showMsg').html(error); //showMsg为你自定义的信息显示区域的id。
   *                   }
   *               }
   *     2)、showErrors
   *         它负责处理事件，当错误产生的时候它会将错误信息显示出来，错误消除时它负责将错误信息隐藏
   *         如果自定义了错误展示，而另外一部分还是默认的行为，则请调用this.defaultShowErrors()
   *         以便默认行为生效，它也有两个参数，分别是errorMap和errorList，是所有错误的集合。
   *         showErrors: function(errorMap, errorList) {
   *                   if(errorList && errorList.length > 0){  //如果存在错误信息
   *                       $.each(errorList,function(index,obj){ //遍历错误信息 ，index为错误信息的索引号，
   *                                                             //obj为当前错误信息对象
   *                           var msg = this.message;           //获取当前错误信息文本
   *                           //这里编写一些代码处理你的错误信息
   *                      });
   *                   }else{
   *                       //错误信息已经消除，此处要写隐藏错误信息的代码，
   *                       //通过this.currentElements获取当前对象
   *                   }
   *                   this.defaultShowErrors();  //如果还有默认的行为，请调用它。
   *               }
   * 4、定制提交方式(ajax提交)
   *   如果使用ajax方式提交，那请采用如下两种方式和校验框架结合
   *   1)、使用submitHandler属性配置ajax提交，submithandler：当表单全部校验通过之后会回调配置的代码，此处也就是当校验通过之后
   *      调用ajax提交，详细代码请察看“ajax表单提交校验”示例代码。
   *   2)、使用valid方法，监听form的submit事件，当$('#form').valid()返回true的时候再提交。
   *       //通过监听form的submit事件，对form进行ajax提交。
           $('#formId').submit(function() {
               if (!$("#formId").valid()) 
                   return false;
               $(this).omAjaxSubmit({});
               return false; //此处必须返回false，阻止常规的form提交
           });
   *   
   * </pre>
   *

   * @constructor
   * @param options 标准config对象
