情况是这样的后端给了几个接口数据 我合成一个

前端小白 勿喷

data(){

return{

list:[{

date:'20201',

mc : '1'

},

{

date:'20202',

mc : '2'

},

{

date:'20203',

mc : '3'

},

{

date:'20204',

mc : '4',

}

],

newlist:[

{

date:'20201',

mc : '6',

age:'12'

},

{

date:'20202',

mc : '3',

age:'12'

},

{

date:'20203',

mc : '2',

age:'12'

},

{

date:'20204',

mc : '1',

age:'12'

}

]

}

},

mounted(){

this.getlist();

},

methods:{

getlist(){

for(var key in this.list){

console.log(this.list[key])

this.newlist.map(item =>{

console.log(item.mc);

if(this.list[key].mc == item.mc){

console.log("名称相等");

this.list[key].age=item.age

}else{

console.log("名称不相等")

}

})

}

console.log(this.list)

}

}
