jQuery Validate
jQuery Validate 插件为表单提供了强大的验证功能,让客户端表单验证变得更简单,同时提供了大量的定制选项,满足应用程序各种需求。
1、导入 js 库
<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>
2、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。 |
例子:
$().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" } })});
