信用卡的jQuery验证仅限于Visa和Mastercard

问题描述

我正在使用jQuery验证插件和其​​他方法插件.我能够验证抄送字段.我有两个问题.

I am using a jQuery validation plugin and an additional methods plugin. I am able to validate CC field. I have two questions.

1. 我如何只限制Visa和Mastercard并显示除这两个以外的消息?
2. 如果我输入"0000000000000000"，验证插件为什么会认为是有效的卡吗?

1. How can I limit only Visa and Mastercard and display a message other than those two?
2. If I enter "0000000000000000" why does the validation plugin think it isa valid card?

我使用了建议的caridtcard验证程序，但出现了错误.

I have used suggested caridtcard validator but geting an error.

推荐答案

我创建了一个如下所示的方法.

I have cretaed a method as below.

  jQuery.validator.addMethod("vmcardsonly", function(value, element, param) {

if( value.charAt(0) == 4 || value.charAt(0) == 5){  
return true;
}else { 
return false;
}

  }, "Please enter a valid Visa or Master credit card number.");


  $('#MyForm').validate({ // initialize the plugin     

        rules: {

            ccNumber1: {
                required: true,             
                number: true,
                vmcardsonly: true,              
                minlength: 16,
                maxlength: 16

            }
        },


        submitHandler: function (form) { // for demo
            alert('valid form submitted'); // for demo
            return false; // for demo
        }
    });
