篇首语:本文由小常识网(cha138.com)小编为大家整理,主要介绍了Validate常用校验相关的知识,希望对你有一定的参考价值。
1、首先将jQuery.js和jquery.validate.js加入对应的页面中,如果要中文的提示语还要把messages_zh.js加入,以及对应的css文件。
<link href="../css/screen.css" rel="stylesheet" /> <script type="text/javascript" src="../js/jquery.js"></script> <script type="text/javascript" src="../js/jquery.validate.js"></script> <script type="text/javascript" src="../js/messages_zh.js"></script> <script type="text/javascript" src="../js/index.js"></script>
对应的html和js代码如下
<form class="cmxform" id="commentForm" method="get" action=""> <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> </form>
$(function() { $("#commentForm").validate(); }); $.validator.setDefaults({ submitHandler: function() { alert("提交事件!"); } });
常用的校验规则:
2、将校验规则写到js中
<form class="cmxform" id="signupForm" method="get" action=""> <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> <input class="submit" type="submit" value="提交"> </p> </fieldset> </form>
$(function() { $("#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"//校验两次密码相同 }, 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" } }) }); $.validator.setDefaults({ submitHandler: function() { alert("提交事件!"); } });
其中 equalTo: "#password" //校验两次密码相同,如果对应的控件没有校验信息则使用默认的校验信息
