jquery验证器方法，检查值是否与给定值匹配并显示错误

Question

我需要对邮政编码进行基本验证，如果为空则显示错误，如果匹配给定值，也会显示错误。

var zip_cde = "1234,5095,2356";
postcode: {
       required: true,
       number: true,
       minlength: 4
      },
 <input type="text" name="postcode" id="postcode" placeholder="5095" >

我希望如果postcoe匹配 zip_cde ，jquery验证器将显示错误。

非常感谢任何帮助。

Answer 1

var zip_cde = "1234,5095,2356";
postcode: {
    required: true,
    number: true,
    postalcode: true
    },

jQuery.validator.addMethod("postalcode", function(postalcode, element) {
return this.optional(element) || (postalcode.match(/^([0-9]{4})$/) && $.inArray(postalcode, zip_cde));
}, "Please enter a valid postcode");

 <input type="text" name="postcode" id="postcode" placeholder="5095" >
