now there is an array of multi-level dots, and you want to reorganize the array according to the dot level level field in this array, with the goal of reassembling a composite array.
the original array code is as follows:
list: [
{
"id": 30064771072,
"lastModified": "2019-02-13 20:14:42:000",
"userCount": 4,
"deviceCount": 4,
"level": 0,
"name": "11"
},
{
"id": 30081548288,
"lastModified": "2019-01-30 14:36:33:729",
"userCount": 0,
"deviceCount": 0,
"level": 1,
"name": ""
},
{
"id": 30081679360,
"lastModified": "2019-01-30 14:23:33:345",
"userCount": 0,
"deviceCount": 0,
"level": 2,
"name": "120"
},
{
"id": 30081744896,
"lastModified": "2019-01-30 06:52:07:915",
"userCount": 0,
"deviceCount": 0,
"level": 2,
"name": "360"
},
{
"id": 30098325504,
"lastModified": "2019-01-29 09:52:27:640",
"userCount": 0,
"deviceCount": 0,
"level": 1,
"name": "120"
},
{
"id": 30131879936,
"lastModified": "2019-01-29 10:14:03:897",
"userCount": 0,
"deviceCount": 0,
"level": 1,
"name": ""
},
{
"id": 30148657152,
"lastModified": "2019-01-30 02:44:48:868",
"userCount": 0,
"deviceCount": 0,
"level": 1,
"name": ""
},
{
"id": 30165434368,
"lastModified": "2019-01-30 14:39:28:452",
"userCount": 0,
"deviceCount": 0,
"level": 1,
"name": ""
},
{
"id": 30182211584,
"lastModified": "2019-01-30 15:32:40:672",
"userCount": 0,
"deviceCount": 0,
"level": 1,
"name": ""
},
{
"id": 30215766016,
"lastModified": "2019-01-30 15:33:17:230",
"userCount": 0,
"deviceCount": 0,
"level": 1,
"name": ""
},
{
"id": 30232543232,
"lastModified": "2019-01-30 07:35:41:689",
"userCount": 0,
"deviceCount": 0,
"level": 1,
"name": "77"
},
{
"id": 30249320448,
"lastModified": "2019-01-30 08:30:30:981",

], level is a site rating field, which has four levels: 0meme, 1meme, 2pje 3. The target array is based on this rating
the target array code is as follows:
listBox:[{//
id:"",
name:"",
lastModified:"",
userCount:"",
deviceCount:"",
children:[{ //
id:"",
name:"",
lastModified:"",
userCount:"",
deviceCount:"",
maxList:[ {//
id:"",
name:"",
lastModified:"",
userCount:"",
deviceCount:"",
minList:[]//
}]
}]
}],
I originally intended to use the for loop to nest the if implementation, but the implementation was modified several times
and the final implementation code is as follows:
for(let i=0;i<this.list.length;iPP){//
if(this.list[i].level==0){//1
this.listBox[i].children = "";
}else if(this.list[i].level==1){//2
this.listBox[i].children[i].maxList = this.list[i];
this.listBox[i].children[i].mediumList = "",
this.listBox[i].children[i].minList = ""
}else if(this.list[i].level==2){//3
this.listBox[i].children[i].mediumList =this.list[i];
this.listBox[i].children[i].minList = ""
}else {//4
this.listBox[i].children[i].minList = this.list[i];
}
this.listBox[i].id = this.list[i].id;
this.listBox[i].name = this.list[i].name;
this.listBox[i].lastModified = this.list[i].lastModified;
this.listBox[i].userCount = this.list[i].userCount;
this.listBox[i].deviceCount = this.list[i].deviceCount;
}
console.log(this.listBox);
however, my method gets cold when it doesn"t get to console.log. And my method is not efficient, each time the page is loaded, I have to traverse all the data in the for loop. I hope all the great gods can teach us an efficient and feasible method. Thank you very much!
