测试使用版本1.17.0,基础的使用见上一篇博客。
1.导入js
<script type="text/javascript" src="xxx/jquery.min.js"></script>
<script type="text/javascript" src="xxx/jquery.validate.min.js"></script>
<!-- 需要中文提示则导入messages_zh.js -->
<script type="text/javascript" src="xxx/messages_zh.js"></script>
2.默认校验规则
required:true |
必输字段 |
remote: “xxx/validate” | 使用ajax方法调用”xxx/validate”验证输入值 |
email: true | 必须输入正确格式的电子邮件 |
url: true | 必须输入正确格式的网址 |
date: true | 必须输入正确格式的日期,日期校验ie6出错,慎用 |
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 |
number: true | 必须输入合法的数字(整数、小数) |
digits: true | 必须输入整数 |
creditcard: true | 必须输入合法的信用卡号 |
equalTo: ‘#password’ | 输入值必须和#password相同 |
accept: ‘image/*’ |
选择合法类型的文件(MIME), 需引用下载包dist目录下的additional-method.js |
maxlength: 5 | 输入长度最多是5的字符串(汉字算一个字符) |
minlength: 10 | 输入长度最小是10的字符串(汉字算一个字符) |
ran gelengt h: [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) |
range: [5,10] | 输入值必须介于 5 和 10 之间 |
max: 5 | 输入值不能大于5 |
min: 10 |
输入值不能小于10 |
3.默认提示
若导入了中文包,则默认提示信息则会是中文;
位于下载包的 dist/localization/messages_zh.js
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 ).”,
number: “Please enter a valid number.”,
digits: “Please enter only digits.”,
creditcard: “Please enter a valid credit card number.”,
equalTo: “Please enter the same value again.”,
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}.” )
}
4.自定义校验
建议在
additional-methods.js
文件中添加(也可在
jquery.validate.js中添加
)
方法:
addMethod(name, method, message)
-
name:规则名称
-
method:(value, element, param) :value:输入的值,element:校验的标签,param:规则内容
-
message:提示信息
示例:
// 扩展验证(邮政编码)
$("#formId").validate({
rules: {
postcode: {
postcode: true
}
},
messages: {
postcode: {
postcode: '邮编格式不正确'
}
}
...
});
// 建议在additional-method.js中添加
$.validator.addMethod("postcode", function(value, element, param) {
var tel = /^[0-9]{6}$/;
return this.optional(element) || (tel.test(value));
}, "请正确填写您的邮政编码");
