初始数据 menuList:
[
{
createBy: '123',
month: '132',
createTime: '2022-01-17 01:00:45',
updateBy: '123',
year: '345',
qyid: '4',
updateTime: '2022-01-17 01:00:47',
sum: '121',
id: '1',
dabh: '12',
status: '2',
},
{
createBy: '123',
month: '132',
createTime: '2022-01-17 01:00:45',
updateBy: '123',
year: '645',
qyid: '4',
updateTime: '2022-01-17 01:00:47',
sum: '121',
id: '2',
dabh: '12',
status: '2',
},
{
createBy: '123',
month: '132',
createTime: '2022-01-17 01:00:45',
updateBy: '123',
year: '645',
qyid: '4',
updateTime: '2022-01-17 01:00:47',
sum: '121',
id: '6',
dabh: '12',
status: '2',
},
{
createBy: '123',
month: '132',
createTime: '2022-01-17 01:00:45',
updateBy: '123',
year: '3789',
qyid: '4',
updateTime: '2022-01-17 01:00:47',
sum: '121',
id: '1',
dabh: '12',
status: '2',
},
],
newList:[]//初始化新变量接收
定义方法处理数据 filterData(){
var order_sn=[];
this.menuList.map(item=>{
if(order_sn.indexOf(item.year)===-1){
this.newList.push({
year:item.year,
subList:[]
})
order_sn.push(item.year)
}
})
this.newList.map(item=>{
this.menuList.map(items=>{
if(item.year==items.year){
item.subList.push(items)
}
})
})
}
最后输出结果为：

"subList": [
