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:用其余方式替代默认的SUBMIT,好比用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,但也能够在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,能够组合使用
class/attribute/metadata rules.

如下代码特别验证selector类中name='name'是必填项而且 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 name@domain.com"

}

}

})

groups:定义一个组,把几个地方的出错信息赞成放在一个地方,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. 设置惟
false就用其余方法去验证

Code

不用onsubmit验证,就容许用户不管用什么方法去验证,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做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

若是是
true那么删除出错类从出错的元素上而且隐藏出错信息当这个元素被聚焦 .避免和 focusInvalid.一块儿用

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

为了元数据使用其余插件你要包装 你的验证规则 在他们本身的项目中能够用这个特殊的选项

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"
建立错误类的名字为了去寻找存在的错误标签和增长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你能够改为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
在出错信息外用其余的元素包装一层。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!") }
})
