jQuery Validation usage tutorial

1. Import js library

jQuery Validation is based on jQuery as the core, so you must first import the jQuery core js file

<script src="<%=path%>/js/bootstrap/jquery-3.2.1.min.js"></script>

Then import the jQuery Validation core js

<script src="<%=path%>/js/jqueryValidation/jquery.validate.min.js"></script>

Import Chinese prompt information js

<script src="<%=path%>/js/jqueryValidation/messages_zh.js"></script>

2. Default verification rules

3 , Default prompt

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}." )
}

Since the Chinese information prompt package has been imported, the default prompt information is:

$.extend( $.validator.messages, {
    required: "这是必填字段",
    remote: "请修正此字段",
    email: "请输入有效的电子邮件地址",
    url: "请输入有效的网址",
    date: "请输入有效的日期",
    dateISO: "请输入有效的日期 (YYYY-MM-DD)",
    number: "请输入有效的数字",
    digits: "只能输入数字",
    creditcard: "请输入有效的信用卡号码",
    equalTo: "你的输入不相同",
    extension: "请输入有效的后缀",
    maxlength: $.validator.format( "最多可以输入 {0} 个字符" ),
    minlength: $.validator.format( "最少要输入 {0} 个字符" ),
    rangelength: $.validator.format( "请输入长度在 {0} 到 {1} 之间的字符串" ),
    range: $.validator.format( "请输入范围在 {0} 到 {1} 之间的数值" ),
    max: $.validator.format( "请输入不大于 {0} 的数值" ),
    min: $.validator.format( "请输入不小于 {0} 的数值" )
} );
