jQuery Validate.js参数以及使用教程

导入 js 库

<script src="../js/jquery.js" type="text/javascript"></script>
<script src="../js/jquery.validate.js" type="text/javascript"></script>

默认校验规则

默认提示

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 gültiges 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>

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，代码如下所示：

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
