ES6中的async函数

 使用前提返回的是一个promiss对象

async selectTableDatas(data){
    this.formItem.partyMeetingSendList='';
    this.partyMeetingSendListFullNames='';
    let idss=[];
    let idBox=[];
    let idsss=[];
    data.map(item=>{
        idss.push({id:item.id});
        idBox.push(item.id);
        idsss.push({userId:item.id});
    });
    this.partyMeetingSendListFullNames= await this.selectFullName(idBox);
    this.formItem.partyMeetingSendList = idsss;
    this.userModal.id=idss;
},

selectFullName(ids){
  return this.get('api/user/getAll?ids='+ ids).then(res => {
        if (res && res.code == 0) {
            return this.formItem.partyMeetingSendListFullNames =(res.data||[]).map(i=>i.fullName).join(',');
        }
        return new Promise.resolve(null);
    })
},
