jquery验证表单validate
1.引用js库
<script src="../js/jquery.js" type="text/javascript"></script>
< script src="../js/jquery.validate.js" type="text/javascript"></script>
2.默认校验规则
(1)required:true 必输字段
(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
3.当未指定对应验证规则出错信息时，默认的出错对应提示如下：
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}.")
}
实例：
<head>
<script src="../../Scripts/jquery-1.7.1.js"></script>
<script src="../../Scripts/jquery.validate.js"></script>
<script type="text/javascript">
$(function () {
$("#form1").validate({ //选择from标签的id
rules: {
userName: {//表单的名称
required: true,
maxlength: 5,
minlength:5
},
messages: {
userName: "*用户名必填，你个傻X",//表单的名称
}
});
})
</script>
</head>
<body>
<div>
<form method="post" id="form1">
<table border="1">
<tr><td>用户名:</td><td><input type="text" name="userName"/></td></tr>
<tr><td>密码：</td><td><input type="password" name="passWord" /></td></tr>
<tr><td>确认密码：</td><td><input type="password" name="passWord2" /></td></tr>
<tr><td>邮箱：</td><td><input type="text" name="userName"/></td></tr>
</table>
<input type="submit" value="提交" />
</form>
</div>
注：当表单不符合验证信息的时候，jquery会在表单后生成<label class="error" for="userName" generated="true">错误信息</lable> 若更改错误信息样式可在页面中<style>.error{color:red}</style>
