组合JSON数据集 [英] Combining JSON Data Sets

问题描述

假设我有以下两个数据集：

Let's say I have the following two data sets:

{ "food": {
    "apple": {
        "color": "red"
        },
    "orange": {
        "color": "orange"
        },
    "potato": {
        "color": "brown"
        },
    "tomato": {
        "color": "red"
        }
    }
}

和

{ "fruits": {
    "apple": {
        "isFruit": "yes"
        },
    "orange": {
        "isFruit": "yes"
       },
    "tomato": {
        "isFruit": "yes"
       }
    }
}

有没有办法将这两个组合起来，使它们最终看起来像： / p>

Is there a way to combine these two sets so that they end up looking like:

{ "food": {
        "apple": {
            "color": "red",
            "isFruit": "yes"
            },
        "orange": {
            "color": "orange",
            "isFruit": "yes"
            },
        "potato": {
            "color": "brown"
            }
        "tomato": {
            "color": "red",
            "isFruit": "yes"
            }
        }
    }

我认为必须有一些方法来解析这两个集并将它们组合起来，但我还没弄清楚如何。

I assume there must be some way to parse these two sets and combine them but I haven't been able to figure out how.

推荐答案

尝试JavaScript 三元运算符 ：

Try JavaScript ternary operator :

var firstJSON = {
	"food": {
		"apple": {
			"color": "red"
		},
		"orange": {
			"color": "orange"
		},
		"potato": {
			"color": "brown"
		},
		"tomato": {
			"color": "red"
		}
	}
};

var secondJSON = {
	"fruits": {
		"apple": {
			"isFruit": "yes"
		},
		"orange": {
			"isFruit": "yes"
		},
		"tomato": {
			"isFruit": "yes"
		}
	}
};

for(var i in firstJSON.food) {
  secondJSON.fruits.hasOwnProperty(i) ? firstJSON.food[i].isFruit = secondJSON.fruits[i].isFruit : '';
}

console.log(firstJSON);
