将键和值都打印到控制台

Question

我正在尝试在表单上呈现一致的错误消息，但我的错误如下：

OBJECT：

{ "email": [ "can't be blank" ], "password": [ "can't be blank" ] }

预期信息

email can't be blank
password can't be blank

那么，如何将该对象转换为“预期消息”？

Answer 1

您可以使用for循环来实现此目的。连接密钥和消息。

var json = { "email": [ "can't be blank" ], "password": [ "can't be blank" ] }

for ( var key in json ) {
    console.log( key + " " + json[key] );
}
