Question

我从服务器收到错误消息的有效json对象。我想遍历每个错误并很好地在网页中显示错误。以下是服务器的json示例

{  
   "contract.cashPrice":[  
      "Cash price is required"
   ],
   "contract.cashDownPayment":[  
      "Cash down payment is required"
   ],
   "contract.effectiveDate":[  
      "Effective date is required"
   ],
   "contract.firstPaymentDate":[  
      "First payment date is required"
   ],
   "contract.mode":[  
      "Mode is required"
   ],
   "contract.numberOfPayments":[  
      "Number of payments is required"
   ],
   "contract.financeChargePercent":[  
      "Finance charge percent is required"
   ]
}

当我循环遍历此错误对象时，我只能接收对象属性，但不能接收值。下面是我到目前为止编写的存根代码。非常感谢任何帮助。

 for(var error in errors){
        error.forEach(function(message){
             console.log(message);
        });
    }

error是errors对象中的关键字。您必须使用它来访问errors中的数组。

for (var error in errors) {
  errors[error].forEach(function(message) {
    console.log(message);
  });
}

嵌套循环JavaScript
