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>
