<script src="../js/jquery.validate.js" type="text/javascript"></script>
二、默认校验规则
(2)remote:"check.php" 使用ajax方法调用check.php验证输入值
(3)email:true 必须输入正确格式的电子邮件
(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
(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
(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
(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）
(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
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}.")
},
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")
});

四、使用方式
<script src="../js/jquery.js" type="text/javascript"></script>
<script src="../js/jquery.validate.js" type="text/javascript"></script>
<script src="./js/jquery.metadata.js" type="text/javascript"></script>
$("#signupForm").validate();
});
<form id="signupForm" method="get" action="">
<p>
<label for="firstname">Firstname</label>
<input id="firstname" name="firstname" class="required" />
</p>
<p>
<label for="email">E-Mail</label>
<input id="email" name="email" class="required email" />
</p>
<p>
<label for="password">Password</label>
<input id="password" name="password" type="password" class="{required:true,minlength:5}" />
</p>
<p>
<label for="confirm_password">确认密码</label>
<input id="confirm_password" name="confirm_password" type="password" class="{required:true,minlength:5,equalTo:'#password'}" />
</p>
<p>
<input class="submit" type="submit" value="Submit"/>
</p>
</form>
class="{required:true,minlength:5,messages:{required:'请输入内容'}}"
class="{required:true,minlength:5,equalTo:'#password'}"
Tell the validation plugin to look inside a validate-property in metadata for validation rules.
例如：
meta: "validate"
<input id="password" name="password" type="password" class="{validate:{required:true,minlength:5}}" />
再有一种方式：
$.metadata.setType("attr", "validate");
$().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"
}
}
});
});
<form id="signupForm" method="get" action="">
<p>
<label for="firstname">Firstname</label>
<input id="firstname" name="firstname" />
</p>
<p>
<label for="email">E-Mail</label>
<input id="email" name="email" />
</p>
<p>
<label for="password">Password</label>
<input id="password" name="password" type="password" />
</p>
<p>
<label for="confirm_password">确认密码</label>
<input id="confirm_password" name="confirm_password" type="password" />
</p>
<p>
<input class="submit" type="submit" value="Submit"/>
</p>
</form>
required:"#aa:checked"表达式的值为真，则需要验证
required:function(){}返回为真，表时需要验证
后边两种常用于，表单中需要同时填或不填的元素
$("#signupForm").validate({
submitHandler:function(form){
alert("submitted");
form.submit();
}
});
});
$.validator.setDefaults({
submitHandler: function(form) { alert("submitted!");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
$().ready(function() {
$("#signupForm").validate({
debug:true
});
});
如果一个页面中有多个表单都想设置成为debug，用
$.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());
}
<tr>
<td class="label"><label id="lfirstname" for="firstname">First Name</label></td>
<td class="field"><input id="firstname" name="firstname" type="text" value="" maxlength="100" /></td>
<td class="status"></td>
</tr>
<tr>
<td style="padding-right: 5px;">
<input id="dateformat_eu" name="dateformat" type="radio" value="0" />
<label id="ldateformat_eu" for="dateformat_eu">14/02/07</label>
</td>
<td style="padding-left: 5px;">
<input id="dateformat_am" name="dateformat" type="radio" value="1" />
<label id="ldateformat_am" for="dateformat_am">02/14/07</label>
</td>
<td></td>
</tr>
<tr>
<td class="label"> </td>
<td class="field" colspan="2">
<div id="termswrap">
<input id="terms" type="checkbox" name="terms" />
<label id="lterms" for="terms">I have read and accept the Terms of Use.</label>
</div>
</td>
</tr>
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() );
}
指定错误提示的css类名，可以自定义错误提示的样式
用什么标签标记错误，默认的是label你可以改成em
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
errorContainer: "#messageBox1, #messageBox2"
把错误信息统一放在一个容器里面。
用什么标签再把上边的errorELement包起来
errorLabelContainer: $("#signupForm div.error"),
wrapper: "li"
label.error {
background:url("./demo/images/unchecked.gif") no-repeat 0px 0px;
}
label.checked {
background:url("./demo/images/checked.gif") no-repeat 0px 0px;
}
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
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<style>label.valid {}</style>
success: "valid"
提交时验证. 设置唯false就用其他方法去验证
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
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
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
$().ready(function() {
var validator = $("#signupForm").validate({
submitHandler:function(form){
alert("submitted");
form.submit();
}
});
$("#reset").click(function() {
validator.resetForm();
});
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
url: "check-email.php", //后台处理程序
type: "post", //数据发送方式
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
自定义验证方法
// 中文字两个字节
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
<input type="radio" id="gender_male" value="m" name="gender" class="{required:true}" />
<input type="radio" id="gender_female" value="f" name="gender"/>
<input type="checkbox" class="checkbox" id="agree" name="agree" class="{required:true}" />
<input type="checkbox" class="checkbox" id="spam_email" value="email" name="spam[]" class="{required:true, minlength:2}" />
<input type="checkbox" class="checkbox" id="spam_phone" value="phone" name="spam[]" />
<input type="checkbox" class="checkbox" id="spam_mail" value="mail" name="spam[]" />
select的required表示选中的value不能为空
<select id="jungle" name="jungle" title="Please select something!" class="{required:true}">
<option value=""></option>
<option value="1">Buga</option>
<option value="2">Baga</option>
<option value="3">Oi</option>
</select>
<select id="fruit" name="fruit" title="Please select at least two fruits" class="{required:true, minlength:2}" multiple="multiple">
<option value="b">Banana</option>
<option value="a">Apple</option>
<option value="p">Peach</option>
<option value="t">Turtle</option>
</select>

在Rails中集成jQuery是一件不错的事情,遗憾一直没时间做这件事情. 其实用jQuery的目的主要是为了表单验证，今天找了个jQuery的验证插件，下载地址： http://bassistance.de/jquery-plugins/jquery-plugin-validation/ 用法太简单了，就在表单中改改class类的值即可。下面为演示实例： 1。导入包： 3。修改表单的class: 完整代码如下： <html> <body> 补充： 可添加的class验证有如下 ： |
<script type="text/javascript">
var
aCity = { 11: "北京", 12: "天津", 13: "河北", 14: "山西", 15: "内蒙古", 21: "辽宁", 22: "吉林", 23: "黑龙江", 31: "上海", 32: "江苏", 33: "浙江", 34: "安徽",
35:"福建",36:"江西",37:"山东",41:"河南",42:"湖北",43:"湖南",44:"广东",45:"广西",46:"海南",50:"重庆",51:"四川",52:"贵州"
,53:"云南",54:"西藏",61:"陕西",62:"甘肃",63:"青海",64:"宁夏",65:"新疆",71:"台湾",81:"香港",82:"澳门",91:"国外"}
function cidInfo(sId){
var iSum=0
var info=""
if(!/^\d{17}(\d|x)$/i.test(sId))return false;
sId=sId.replace(/x$/i,"a");
if(aCity[parseInt(sId.substr(0,2))]==null)return "Error:非法地区";
sBirthday=sId.substr(6,4)+"-"+Number(sId.substr(10,2))+"-"+Number(sId.substr(12,2));
var d=new Date(sBirthday.replace(/-/g,"/"))
if(sBirthday!=(d.getFullYear()+"-"+ (d.getMonth()+1) + "-" + d.getDate()))return "Error:非法生日";
for(var i = 17;i>=0;i --) iSum += (Math.pow(2,i) % 11) * parseInt(sId.charAt(17 - i),11)
if(iSum%11!=1)return "Error:非法证号";
return aCity[parseInt(sId.substr(0,2))]+","+sBirthday+","+(sId.substr(16,1)%2?"男":"女")
}
</script>
<script type="text/javascript">
$(document).ready(function() {
