js循环调用接口，获取每一次接口的值

vue代码。

data数据：

list: [
    {listName:"待办",listNum:0},
    {listName:"退回",listNum:0},
    {listName:"已办",listNum:0},
    {listName:"全部",listNum:0}
],

methods里面的方法：

async getAllData(){
    this.list.map((listItem,index)=>{
        let tabId = '';
        if(index===0) {
            tabId = 'd301b60048e811ec85e763f083b99d99'
        }else if(index===2) {
            tabId = 'cf80ec80a5d611ec84446f0a1ef0fb8d'
        }else if(index===3) {
            tabId = 'd0308d70a5d611ec84446f0a1ef0fb8d'
        }else if(index===1) {
            tabId = '9dcc552037d111ed9487799545a81f0d'
        }
        let data ={
            currpage: 1,
            limit: 10,
            'pm_project_info#PRO_NAME': "",
            'pm_project_info#PRO_ID': null,
            menuId_: '244ed54824a46b4da2029bdac66a2573',
            tabId: tabId,
            templateId: "40f5a4537cc77f0a203a9ea73a54f6f3",
        }
        this.$api.businessData(data).then(_res=>{   //封装的接口
            listItem.listNum = _res.data.result.total;
        });
    })
},
