测试使用版本1.17.0,基础的使用见上一篇博客。


1.导入js

<script type="text/javascript" src="xxx/jquery.min.js"></script>
<script type="text/javascript" src="xxx/jquery.validate.min.js"></script>
<!-- 需要中文提示则导入messages_zh.js -->
<script type="text/javascript" src="xxx/messages_zh.js"></script>




2.默认校验规则


required:true
必输字段
remote: “xxx/validate” 使用ajax方法调用”xxx/validate”验证输入值
email: true 必须输入正确格式的电子邮件
url: true 必须输入正确格式的网址
date: true 必须输入正确格式的日期,日期校验ie6出错,慎用
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
number: true 必须输入合法的数字(整数、小数)
digits: true 必须输入整数
creditcard: true 必须输入合法的信用卡号
equalTo: ‘#password’ 输入值必须和#password相同
accept: ‘image/*’ 选择合法类型的文件(MIME),

需引用下载包dist目录下的additional-method.js
maxlength: 5 输入长度最多是5的字符串(汉字算一个字符)
minlength: 10 输入长度最小是10的字符串(汉字算一个字符)
ran

gelengt

h: [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)
range: [5,10] 输入值必须介于 5 和 10 之间
max: 5 输入值不能大于5
min: 10

输入值不能小于10















3.默认提示



若导入了中文包,则默认提示信息则会是中文;

位于下载包的 dist/localization/messages_zh.js




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 ).”,



number: “Please enter a valid number.”,



digits: “Please enter only digits.”,



creditcard: “Please enter a valid credit card number.”,



equalTo: “Please enter the same value again.”,



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}.” )

}






4.自定义校验


建议在






additional-methods.js

文件中添加(也可在

jquery.validate.js中添加






方法:



addMethod(name, method, message)


  • name:规则名称

  • method:(value, element, param) :value:输入的值,element:校验的标签,param:规则内容

  • message:提示信息

示例:

// 扩展验证(邮政编码)
$("#formId").validate({
    rules: {
        postcode: {
            postcode: true
        }
    },
    messages: {
        postcode: {
            postcode: '邮编格式不正确'
        }
    }
    ...
});

// 建议在additional-method.js中添加
$.validator.addMethod("postcode", function(value, element, param) {
	var tel = /^[0-9]{6}$/;
	return this.optional(element) || (tel.test(value));	
}, "请正确填写您的邮政编码");
