原本remote方法，後臺只會返回true或false，無法返回錯誤的資訊

現在將remote的返回內容改為json格式

String message1 = "{\"success\":false,\"message\":\"手機號碼輸入不正確\"}";

String message2 = "{\"success\":false,\"message\":\"您的會員卡號或者手機號碼已經被註冊\"}";

接著開啟jquery.validate.js中remote方法的原始碼

success: function(response) {
 

     validator.settings.messages[element.name].remote = previous.originalMessage;
     var valid = response === true;
     if ( valid ) {
        ......
     } else {
        ......
     }
     previous.valid = valid;
     validator.stopRequest(element, valid);
}

validator.settings.messages[element.name].remote 
 
= previous.originalMessage;
     var valid = response === true;

var tempResponse = response;

if (tempResponse.success != undefined) {
      response = tempResponse.success;
}
if (tempResponse.message != undefined) {
      validator.settings.messages[element.name].remote = tempResponse.message;
} else {
      validator.settings.messages[element.name].remote = previous.originalMessage;
}
var valid = response === true;
