JQuery Validate使用总结

一、导入js库
<script src="../js/jquery.js" type="text/javascript"></script>
<script src="../js/jquery.validate.js" type="text/javascript"></script>

二、默认校验规则
(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
(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 日期校验ie6出错，慎用
(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
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
<script src="../js/messages_cn.js" type="text/javascript"></script>

四、使用方式

1.将校验规则写到控件中
<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>
$().ready(function() {
    $("#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 >
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'}"


2.将校验规则写到js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

< 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: 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


demo：
$("#form1").validate({ //JQ 前端校验
    rules: {
        ctl00$MainContent$txtWebName: {
            required: true,
            maxlength: 500
        },
        ctl00$MainContent$txtShortName: {
            maxlength: 500,
            required: false
        },
        ctl00$MainContent$txtKeyWords: {

        },

            required: false,
            number: true
        },
        ctl00$MainContent$txtFullCash: {
            required: true,
            number: true
        }
    },
    messages: {
        ctl00$MainContent$txtWebName: "*请输入商品名[限500字以内]",
        ctl00$MainContent$txtShortName: "*限500字以内",
