主干/chaplinJS:如何检查对象中是否存在密钥

Question

{
                  "providerProperties": [
                    {
                      "key": "hotelnum",
                      "value": "123"
                    },
                    {
                      "key": "contract",
                      "value": "ABC"
                    },
                    {
                      "key": "Sequence",
                      "value": "1213"
                    },
                    {

                      "value": "5454"
                    },
                    {
                      "key": "shop",
                      "value": "abc"
                    },
                    {
                      "key": "bookingEmailAddress",
                      "value": "abc@gmail.COM"
                    },
                    {
                      "key": "numOfRooms",
                      "value": "1"
                    }
}

主干/chaplinJS:如何检查对象中是否存在密钥。例如，要检查"numOfRooms“键是否可用。

Answer 1

如果结果不是findWhere，则可以使用下划线方法_.findWhere(yourObject.providerProperties, {key: "numOfRooms"});之类的下划线方法，然后它就出现了。
