点击请假审批后会弹出一个空白提示框，该怎么让这个不见？

这是用el组件开发的，要提供一整套才行，我看有其他人也有过相似的问题，应该是课程里提供的前端源码有问题

,(){
    =;
    =.();
    .(+.eid)
    .((response){
        =response.;
        (.==){
            ..(,..);
            =..;
            .((item){
                (item.form_type){
                    :
                        item.=;
                    :
                        item.=;
                    :
                        item.=;
                    :
                        item.=;
                    :
                        item.=;
                    :
                        item.=;
                }
                item.=(item.start_time);
                item.=(item.end_time);
                item.=(item.create_time);
                ..(item);
            })
        }{
            .({:.,:})
        }
    })
}

经过自己逐个排查问题应该出在这段话里，但是我不知道怎么修改

,mounted(){
    const objApp=this;
    const $message=this.$message();
    axios.get("api/leave/list?eid="+sessionStorage.eid)
    .then(function (response){
        const json=response.data;
        if(json.code==0){
            //清空原始的所有数据
            objApp.tableData.splice(0,objApp.tableData.length);
            const formList=json.data.list;
            formList.forEach(function (item){
                switch (item.form_type){
                    case 1:
                        item.ftype="事假"
                        break;
                    case 2:
                        item.ftype="病假"
                        break;
                    case 3:
                        item.ftype="工伤假"
                        break;
                    case 4:
                        item.ftype="婚假"
                        break;

                        break;
                    case 6:
                        item.ftype="丧假"
                        break;
                }
                item.stime=formatDate(item.start_time);
                item.etime=formatDate(item.end_time);
                item.ctime=formatDate(item.create_time);
                objApp.tableData.push(item);
            })
        }else{
            $message.error({message:json.message,offset:100})
        }
    })
}
