jquery-validation验证插件

参考网站:菜鸟教程

一.导入js

<script src="http://static.runoob.com/assets/jquery-validation-1.14.0/lib/jquery.js"></script>
<script src="http://static.runoob.com/assets/jquery-validation-1.14.0/dist/jquery.validate.min.js"></script>

二.默认校验规则

序号规则描述
1 required:true 必须输入的字段。
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 gltiges 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_zh.js中,在页面中引入

<script src="jquery-validation-1.14.0/dist/localization/messages_zh.js"></script>

使用方式

1、将校验规则写到控件中

<script src="http://static.runoob.com/assets/jquery-validation-1.14.0/lib/jquery.js"></script>
<script src="http://static.runoob.com/assets/jquery-validation-1.14.0/dist/jquery.validate.min.js"></script>
<script src="http://static.runoob.com/assets/jquery-validation-1.14.0/dist/localization/messages_zh.js"></script>
<script>
$.validator.setDefaults({
    submitHandler: function() {
      alert("提交事件!");
    }
});
$().ready(function() {
    $("#commentForm").validate();
});
</script>

<form class="cmxform" id="commentForm" method="get" action="">
  <fieldset>
    <legend>输入您的名字,邮箱,URL,备注。</legend>
    <p>
      <label for="cname">Name (必需, 最小两个字母)</label>
      <input id="cname" name="name" minlength="2" type="text" required>
    </p>
    <p>
      <label for="cemail">E-Mail (必需)</label>
      <input id="cemail" type="email" name="email" required>
    </p>
    <p>
      <label for="curl">URL (可选)</label>
      <input id="curl" type="url" name="url">
    </p>
    <p>
      <label for="ccomment">备注 (必需)</label>
      <textarea id="ccomment" name="comment" required></textarea>
    </p>
    <p>
      <input class="submit" type="submit" value="Submit">
    </p>
  </fieldset>
</form>

2、将校验规则写到 js 代码中

$().ready(function() {
// 在键盘按下并释放及提交后验证提交表单
  $("#signupForm").validate({
    rules: {
      firstname: "required",
      lastname: "required",
      username: {
        required: true,
        minlength: 2
      },
      password: {
        required: true,
        minlength: 5
      },
      confirm_password: {
        required: true,
        minlength: 5,
        equalTo: "#password"
      },
      email: {
        required: true,
        email: true
      },
      topic: {
        required: "#newsletter:checked",
        minlength: 2
      },
      agree: "required"
    },
    messages: {
      firstname: "请输入您的名字",
      lastname: "请输入您的姓氏",
      username: {
        required: "请输入用户名",
        minlength: "用户名必需由两个字母组成"
      },
      password: {
        required: "请输入密码",
        minlength: "密码长度不能小于 5 个字母"
      },
      confirm_password: {
        required: "请输入密码",
        minlength: "密码长度不能小于 5 个字母",
        equalTo: "两次密码输入不一致"
      },
      email: "请输入一个正确的邮箱",
      agree: "请接受我们的声明",
      topic: "请选择两个主题"
    }
});

 

messages 处,如果某个控件没有 message,将调用默认的信息

<form class="cmxform" id="signupForm" method="get" action="">
  <fieldset>
    <legend>验证完整的表单</legend>
    <p>
      <label for="firstname">名字</label>
      <input id="firstname" name="firstname" type="text">
    </p>
    <p>
      <label for="lastname">姓氏</label>
      <input id="lastname" name="lastname" type="text">
    </p>
    <p>
      <label for="username">用户名</label>
      <input id="username" name="username" type="text">
    </p>
    <p>
      <label for="password">密码</label>
      <input id="password" name="password" type="password">
    </p>
    <p>
      <label for="confirm_password">验证密码</label>
      <input id="confirm_password" name="confirm_password" type="password">
    </p>
    <p>
      <label for="email">Email</label>
      <input id="email" name="email" type="email">
    </p>
    <p>
      <label for="agree">请同意我们的声明</label>
      <input type="checkbox" class="checkbox" id="agree" name="agree">
    </p>
    <p>
      <label for="newsletter">我乐意接收新信息</label>
      <input type="checkbox" class="checkbox" id="newsletter" name="newsletter">
    </p>
    <fieldset id="newsletter_topics">
      <legend>主题 (至少选择两个) - 注意:如果没有勾选“我乐意接收新信息”以下选项会隐藏,但我们这里作为演示让它可见</legend>
      <label for="topic_marketflash">
        <input type="checkbox" id="topic_marketflash" value="marketflash" name="topic">Marketflash
      </label>
      <label for="topic_fuzz">
        <input type="checkbox" id="topic_fuzz" value="fuzz" name="topic">Latest fuzz
      </label>
      <label for="topic_digester">
        <input type="checkbox" id="topic_digester" value="digester" name="topic">Mailing list digester
      </label>
      <label for="topic" class="error">Please select at least two topics you'd like to receive.</label>
    </fieldset>
    <p>
      <input class="submit" type="submit" value="提交">
    </p>
  </fieldset>
</form>
