(1)required:true 必输字段

(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

(17)min:10 输入值不能小于10
messages: { required:"This field is required.", remote:"Please fix this field.", email:"Please enter a valid email address.", url: "Pleaseenter 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
<script src="../js/messages_cn.js"type="text/javascript"></script>
<scriptsrc="../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> $().ready(function() { $("#signupForm").validate(); }); <form id="signupForm" method="get"action=""> <p> <labelfor="firstname">Firstname</label> <input id="firstname" name="firstname"class="required" /> </p> <p> <labelfor="email">E-Mail</label> <inputid="email" name="email" class="required email"/> </p> <p> <labelfor="password">Password</label> <inputid="password" name="password" type="password"class="{required:true,minlength:5}" /> </p> <p> <labelfor="confirm_password">确认密码</label> <inputid="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>
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:
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'}"
$().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 <form id="signupForm" method="get"action=""> <p> <labelfor="firstname">Firstname</label> <input id="firstname" name="firstname"/> </p> <p> <labelfor="email">E-Mail</label> <inputid="email" name="email" /> </p> <p> <labelfor="password">Password</label> <inputid="password" name="password" type="password"/> </p> <p> <labelfor="confirm_password">确认密码</label> <inputid="confirm_password" name="confirm_password" type="password"/> </p> <p> <input class="submit" type="submit"value="Submit"/> </p> </form>
required:true必须有值
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。
