基础数据
let eduLevelArray = [
{
id: "1",
name: "张三",
edu: "小学"
},{
id: "2",
name: "李四",
edu: "初中"
},{
id: "1",
name: "张三",
edu: "高中"
},{
id: "2",
name: "李四",
edu: "大学"
},{
id: "3",
name: "王五",
edu: "研究生"
}];
执行方法
let reArr = eduLevelArray.reduce((obj, item) => {
if(obj[item.id]){
obj[item.id].edu.push(item.edu)
}else{
item.edu = [item.edu]
obj[item.id] = {...item}
}
return obj;
}, {});
//执行Object方法
let mergedArray = Object.values(reArr);
console.log(mergedArray)
输出结果：
mergedArray = [{
id: "1",
name: "张三",
edu:["小学", "高中"]
},{
id: "2",
name: "李四",
edu: ["初中", "大学"]
},{
id: "3",
name: "王五",
edu: ["研究生"]
}]
