我需要帮助根据父ID属性匹配相同对象中的子项....
JSON：
{
"1": {
"id": 1,
"name": "My Crib",
"type": "Home",
"order": 0,
"parent": null
},
"2": {
"id": 2,
"name": "First floor",
"type": "Floor",
"order": 1,
"parent": {
"id": 1,
"url": "http://localhost:8080/rest/areas/1"
}
},
"3": {
"id": 3,
"name": "Garage",
"type": "Garage",
"order": 2,
"parent": {
"id": 1,
"url": "http://localhost:8080/rest/areas/1"
}
},
"4": {
"id": 4,
"name": "Garden",
"type": "Garden",
"order": 3,
"parent": {
"id": 1,
"url": "http://localhost:8080/rest/areas/1"
}
},
"5": {
"id": 5,
"name": "Entrance hall",
"type": "Entrance",
"order": 1,
"parent": {
"id": 2,
"url": "http://localhost:8080/rest/areas/2"
}
},
"6": {
"id": 6,
"name": "Kitchen",
"type": "Kitchen",
"order": 2,
"parent": {
"id": 2,
"url": "http://localhost:8080/rest/areas/2"
}
},
"7": {
"id": 7,
"name": "Living room",
"type": "LivingRoom",
"order": 3,
"parent": {
"id": 2,
"url": "http://localhost:8080/rest/areas/2"
}
},
"8": {
"id": 8,
"name": "Dog house",
"type": "DogHouse",
"order": 1,
"parent": {
"id": 4,
"url": "http://localhost:8080/rest/areas/4"
}
}
}
const mappedAreas = Object.keys(areas).map(function(key) {
const area = areas[key];
const wrappers = statics["test.area.groups"]["wrappers"];
const leafs = statics["test.area.groups"]["leafs"];
if (wrappers.indexOf(area["type"]) > -1) {
//In the array!
//If not a home
if(area["type"] != "Home"){
console.log("floor:")
console.log(area)
//get wrapper childrens
const children = Object.keys(areas).map(function(key) {
const child = areas[key];
if(child["type"] != "Home"){
if(child["parent"]["id"] == area["id"] && leafs.indexOf(child["type"]) > -1){
console.log(child);
//return <Area key={"area_index_"+key} areaData={area} />
}
}
});
console.log("endfloor/")
//return <Area key={"area_index_"+key} areaData={area} />
}
} else {
//Not in the array
}
});
有没有办法比在另一张地图中放置一张地图更好？
基本上我将所有区域都放在一个对象中，我希望将它们与彼此匹配，寻找[＆＃34;父母＆＃34;] [＆＃34; id＆＃34;]以匹配[＆＃34 ; ID＆＃34]。
告诉我你是否需要更多描述。
