validate ()的可选项        
debug：进行调试模式        
$(".selector").validate        
({        
     debug: true    
})        
    把调试设置为默认        
        
$.validator.setDefaults({        
     debug: true    
})        
        
submitHandler：用其他方式替代默认的SUBMIT,比如用AJAX的方式提交        
        
$(".selector").validate({        
     submitHandler: function(form) {        
        $(form).ajaxSubmit();        
     }        
})        
        
ignore：忽略某些元素不验证        
$("#myform").validate({        
     ignore: ".ignore"    
})        
        
rules： 默认下根据form的classes, attributes, metadata判断，但也可以在validate函数里面声明        
Key/value 可自定义规则. Key是对象的名字 value是对象的规则，可以组合使用 class/attribute/metadata rules.        
以下代码特别验证selector类中name='name'是必填项并且 email是既是必填又要符合email的格式        
        
$(".selector").validate({        
     rules: {        
         // simple rule, converted to {required:true}        
         name: "required",        
         // compound rule        
         email: {        
             required: true,        
             email: true    
         }        
     }        
})        
        
messages：更改默认的提示信息        
        
$(".selector").validate({        
     rules: {        
         name: "required",        
         email: {        
             required: true,        
             email: true    
         }        
     },        
     messages: {        
         name: "Please specify your name",        
         email: {        
             required: "We need your email address to contact you",        
             email: "Your email address must be in the format of [email protected]"    
         }        
     }        
})        
groups：定义一个组，把几个地方的出错信息同意放在一个地方，用error Placement控制把出错信息放在哪里        
        
$("#myform").validate({        
    groups: {        
        username: "fname lname"    
    },        
    errorPlacement: function(error, element) {        
         if (element.attr("name") == "fname" || element.attr("name") == "lname" )        
             error.insertAfter("#lastname");        
         else    
             error.insertAfter(element);        
     },        
     debug:true    
})        
        
nsubmit Boolean Default: true    
提交时验证. 设置唯false就用其他方法去验证        
Code        
不用onsubmit验证,就允许用户无论用什么方法去验证,而是提交时, 用 keyup/blur/click 等方法.        
$(".selector").validate({        
     onsubmit: false    
})        
onfocusout    Boolean Default: true    
Validate elements (except checkboxes/radio buttons) on blur. If nothing is entered, all rules are skipped, except when the field was already marked as invalid.        
Code        
Disables onblur validation.        
$(".selector").validate({        
     onfocusout: false    
})        
onkeyup Boolean Default: true    
在keyup时验证. As long as the field is not marked as invalid, nothing happens. Otherwise, all rules are checked on each key up event.        
Code        
Disables onkeyup validation.        
$(".selector").validate({        
     onkeyup: false    
})        
onclick Boolean Default: true    
在checkboxes 和 radio 点击时验证.        
Code        
Disables onclick validation of checkboxes and radio buttons.        
$(".selector").validate({        
     false    
})        
focusInvalid        Boolean Default: true    
把焦点聚焦在最后一个动作或者最近的一次出错上via validator.focusInvalid(). The last active element is the one that had focus when the form was submitted, avoiding to steal its focus. If there was no element focused, the first one in the form gets it, unless this option is turned off.        
Code        
Disables focusing of invalid elements.        
$(".selector").validate({        
     focusInvalid: false    
})        
focusCleanup        Boolean Default: false    
如果是true那么删除出错类从出错的元素上并且隐藏出错信息当这个元素被聚焦 .避免和 focusInvalid.一起用        
Code        
Enables cleanup when focusing elements, removing the error class and hiding error messages when an element is focused.        
$(".selector").validate({        
     focusCleanup: true    
})        
meta        String            
为了元数据使用其他插件你要包装 你的验证规则 在他们自己的项目中可以用这个特殊的选项        
Tell the validation plugin to look inside a validate-property in metadata for validation rules.        
$("#myform").validate({        
     meta: "validate",        
     submitHandler: function() { alert("Submitted!") }        
})

errorClass    String    Default: "error"    
创建错误类的名字为了去寻找存在的错误标签和增加它到验证失败的元素中去。        
Code        
Sets the error class to "invalid".        
$(".selector").validate({        
     errorClass: "invalid"    
})        
errorElement        String    Default: "label"    
设置错误的元素，默认的是label你可以改成em.Use this element type to create error messages and to look for existing error messages. The default, "label", has the advantage of creating a meaningful link between error message and invalid field using the for attribute (which is always used, no matter the element type).        
Code        
Sets the error element to "em".        
$(".selector").validate        
     errorElement: "em"    
})        
wrapper String            
在出错信息外用其他的元素包装一层。Wrap error labels with the specified element. Useful in combination with errorLabelContainer to create a list of error messages.        
Code        
Wrap each error element with a list item, useful when using an ordered or unordered list as the error container.        
$(".selector").validate({        
     wrapper: "li"    
})        
errorLabelContainer Selector                
把错误信息统一放在一个容器里面。Hide and show this container when validating.        
All error labels are displayed inside an unordered list with the ID "messageBox", as specified by the selector passed as errorContainer option. All error elements are wrapped inside an li element, to create a list of messages.        
$("#myform").validate({        
     errorLabelContainer: "#messageBox",        
     wrapper: "li",        
     submitHandler: function() { alert("Submitted!") }        
})
