一、用前必备</strong>
官方网站:<a href=”http://bassistance.de/jquery-plugins/jquery-plugin-validation/”>http://bassistance.de/jquery-plugins/jquery-plugin-validation/
API: http://jquery.bassistance.de/api-browser/plugins.html
当前版本:1.5.5
需要JQuery版本:1.2.6+, 兼容 1.3.2

二、默认校验规则</strong>
(1)required:true 必输字段
(2)remote:”check.php” 使用ajax方法调用check.php验证输入值<br />
(3)email:true 必须输入正确格式的电子邮件<br />
(4)url:true 必须输入正确格式的网址
(5)date:true 必须输入正确格式的日期<br />
(6)dateISO:true 必须输入正确格式的日期(ISO),例如:2009-06-23,1998/01/22 只验证格式,不验证有效性<br />
(7)number:true 必须输入合法的数字(负数,小数)
(8)digits:true 必须输入整数
(9)creditcard: 必须输入合法的信用卡号<br />
(10)equalTo:”#field” 输入值必须和#field相同
(11)accept: 输入拥有合法后缀名的字符串(上传文件的后缀)<br />
(12)maxlength:5 输入长度最多是5的字符串(汉字算一个字符)
(13)minlength:10 输入长度最小是10的字符串(汉字算一个字符)
(14)rangelength:[5,10] 输入长度必须介于 5 和 10 之间的字符串”)(汉字算一个字符)
(15)range:[5,10] 输入值必须介于 5 和 10 之间
(16)max:5 输入值不能大于5
(17)min:10 输入值不能小于10
三、默认的提示
messages: {
required: “This field is required.”,
remote: “Please fix this field.”,
email: “Please enter a valid email address.”,
url: “Please enter a valid URL.”,
date: “Please enter a valid date.”,
dateISO: “Please enter a valid date (ISO).”,
dateDE: “Bitte geben Sie ein g眉ltiges Datum ein.”,
number: “Please enter a valid number.”,
numberDE: “Bitte geben Sie eine Nummer ein.”,
digits: “Please enter only digits”,
creditcard: “Please enter a valid credit card number.”,
equalTo: “Please enter the same value again.”,
accept: “Please enter a value with a valid extension.”,
maxlength: $.validator.format(“Please enter no more than {0} characters.”),
minlength: $.validator.format(“Please enter at least {0} characters.”),
rangelength: $.validator.format(“Please enter a value between {0} and {1} characters long.”),
range: $.validator.format(“Please enter a value between {0} and {1}.”),
max: $.validator.format(“Please enter a value less than or equal to {0}.”),
min: $.validator.format(“Please enter a value greater than or equal to {0}.”)
},
如需要修改,可在js代码中加入:
jQuery.extend(jQuery.validator.messages, {
required: “必选字段",
remote: “请修正该字段”,
email: “请输入正确格式的电子邮件”,
url: “请输入合法的网址”,
date: “请输入合法的日期”,
dateISO: “请输入合法的日期 (ISO).”,
number: “请输入合法的数字”,
digits: “只能输入整数”,
creditcard: “请输入合法的信用卡号”,
equalTo: “请再次输入相同的值",
accept: “请输入拥有合法后缀名的字符串",
maxlength: jQuery.validator.format(“请输入一个长度最多是 {0} 的字符串”),
minlength: jQuery.validator.format(“请输入一个长度最少是 {0} 的字符串”),
rangelength: jQuery.validator.format(“请输入一个长度介于 {0} 和 {1} 之间的字符串”),
range: jQuery.validator.format(“请输入一个介于 {0} 和 {1} 之间的值"),
max: jQuery.validator.format(“请输入一个最大为 {0} 的值"),
min: jQuery.validator.format(“请输入一个最小为 {0} 的值")
});
推荐做法,将此文件放入messages_cn.js中,在页面中引入
四、使用方式</strong>
1.将校验规则写到控件中


$().ready(function() {
$(“#signupForm”).validate();
});





使用class=”{}”的方式,必须引入包:jquery.metadata.js
可以使用如下的方法,修改提示内容:<br />
class=”{required:true,minlength:5,messages:{required:’请输入内容'}}”
在使用equalTo关键字时,后面的内容必须加上引号,如下代码:
class=”{required:true,minlength:5,equalTo:’#password’}”
另外一个方式,使用关键字:meta(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)<br />
Tell the validation plugin to look inside a validate-property in metadata for validation rules.
例如:<br />
meta: “validate”
再有一种方式:
$.metadata.setType(“attr”, “validate”);
这样可以使用validate=”{required:true}”的方式,或者class=”required”,但class=”{required:true,minlength:5}”将不起作用</div>

2.将校验规则写到代码中
$().ready(function() {
$(“#signupForm”).validate({
rules: {
firstname: “required”,
email: {
required: true,
email: true
},
password: {
required: true,
minlength: 5
},
confirm_password: {
required: true,
minlength: 5,
equalTo: “#password”
}
},
messages: {
firstname: “请输入姓名",
email: {
required: “请输入Email地址”,
email: “请输入正确的email地址”
},
password: {
required: “请输入密码",
minlength: jQuery.format(“密码不能小于{0}个字符")
},
confirm_password: {
required: “请输入确认密码",
minlength: “确认密码不能小于5个字符",
equalTo: “两次输入密码不一致不一致"
}
}
});
});
//messages处,如果某个控件没有message,将调用默认的信息</div>





required:true 必须有值<br />
required:”#aa:checked”表达式的值为真,则需要验证<br />
required:function(){}返回为真,表时需要验证<br />
后边两种常用于,表单中需要同时填或不填的元素
五、常用方法及注意问题
1.用其他方式替代默认的SUBMIT
$().ready(function() {
$(“#signupForm”).validate({
submitHandler:function(form){
alert(“submitted”);
form.submit();
}
});
});
可以设置validate的默认值,写法如下:<br />
$.validator.setDefaults({
submitHandler: function(form) { alert(“submitted!”);form.submit(); }
});
如果想提交表单, 需要使用form.submit()而不要使用$(form).submit()
2.debug,如果这个参数为true,那么表单不会提交,只进行检查,调试时十分方便<br />
$().ready(function() {
$(“#signupForm”).validate({
debug:true
});
});
如果一个页面中有多个表单,用<br />
$.validator.setDefaults({
debug: true
})
3.ignore:忽略某些元素不验证
ignore: “.ignore”
4.errorPlacement:Callback Default: 把错误信息放在验证的元素后面
指明错误放置的位置,默认情况是:error.appendTo(element.parent());即把错误信息放在验证的元素后面
errorPlacement: function(error, element) {
error.appendTo(element.parent());
}
//示例:<br />



 


errorPlacement: function(error, element) {
if ( element.is(“:radio”) )
error.appendTo( element.parent().next().next() );
else if ( element.is(“:checkbox”) )
error.appendTo ( element.next() );
else
error.appendTo( element.parent().next() );
}
代码的作用是:一般情况下把错误信息显示在

中,如果是radio显示在&lt;td>

中,如果是checkbox显示在内容的后面

errorClass:String Default: “error”
指定错误提示的css类名,可以自定义错误提示的样式</div>

errorElement:String Default: “label”
用什么标签标记错误,默认的是label你可以改成em
errorContainer:Selector
显示或者隐藏验证信息,可以自动实现有错误信息出现时把容器属性变为显示,无错误时隐藏,用处不大<br />
errorContainer: “#messageBox1, #messageBox2”
errorLabelContainer:Selector
把错误信息统一放在一个容器里面。</div>

wrapper:String
用什么标签再把上边的errorELement包起来</div>

一般这三个属性同时使用,实现在一个容器内显示所有错误提示的功能,并且没有信息时自动隐藏
errorContainer: “div.error”,
errorLabelContainer: $(“#signupForm div.error”),
wrapper: “li”
设置错误提示的样式,可以增加图标显示
input.error { border: 1px solid red; }
label.error {
background:url(“./demo/images/unchecked.gif”) no-repeat 0px 0px;
padding-left: 16px;
padding-bottom: 2px;
font-weight: bold;
color: #EA5200;
}
label.checked {
background:url(“./demo/images/checked.gif”) no-repeat 0px 0px;
}
success:String,Callback
要验证的元素通过验证后的动作,如果跟一个字符串,会当做一个css类,也可跟一个函数<br />
success: function(label) {
// set   as text for IE
label.html(” “).addClass(“checked”);
//label.addClass(“valid”).text(“Ok!”)
}
添加”valid” 到验证元素, 在CSS中定义的样式

success: “valid”

nsubmit: Boolean Default: true
提交时验证. 设置唯false就用其他方法去验证<br />
onfocusout:Boolean Default: true
失去焦点是验证(不包括checkboxes/radio buttons)
onkeyup:Boolean Default: true
在keyup时验证.
onclick:Boolean Default: true
在checkboxes 和 radio 点击时验证<br />
focusInvalid:Boolean Default: true
提交表单后,未通过验证的表单(第一个或提交之前获得焦点的未通过验证的表单)会获得焦点<br />
focusCleanup:Boolean Default: false
如果是true那么当未通过验证的元素获得焦点时,移除错误提示。避免和 focusInvalid 一起用
// 重置表单
$().ready(function() {
var validator = $(“#signupForm”).validate({
submitHandler:function(form){
alert(“submitted”);
form.submit();
}
});
$(“#reset”).click(function() {
validator.resetForm();
});
});
remote:URL
使用ajax方式进行验证,默认会提交当前验证的值到远程地址,如果需要提交其他的值,可以使用data选项
remote: “check-email.php”
remote: {
url: “check-email.php”, //后台处理程序
type: “post”, //数据发送方式<br />
dataType: “json”, //接受数据格式
data: { //要传递的数据
username: function() {
return $(“#username”).val();
}
}
}
远程地址只能输出 “true” 或 “false”,不能有其它输出
addMethod:name, method, message
自定义验证方法</div>

// 中文字两个字节<br />
jQuery.validator.addMethod(“byteRangeLength”, function(value, element, param) {
var length = value.length;
for(var i = 0; i < value.length; i++){
if(value.charCodeAt(i) > 127){
length++;
}
}
return this.optional(element) || ( length >= param[0] && length <= param[1] );
}, $.validator.format(“请确保输入的值在{0}-{1}个字节之间(一个中文字算2个字节)”));
// 邮政编码验证
jQuery.validator.addMethod(“isZipCode”, function(value, element) {
var tel = /^[0-9]{6}$/;
return this.optional(element) || (tel.test(value));
}, “请正确填写您的邮政编码");
radio和checkbox、select的验证</div>

radio的required表示必须选中一个<br />

checkbox的required表示必须选中
checkbox的minlength表示必须选中的最小个数,maxlength表示最大的选中个数,rangelength:[2,3]表示选中个数区间


select的required表示选中的value不能为空
select的minlength表示选中的最小个数(可多选的select),maxlength表示最大的选中个数,rangelength:[2,3]表示选中个数区间
