关于vue.js:前端不等待后端执行

后端不向前端返回数据然而都端须要继续执行而前端不处于loading过程

this.$confirm(  '提醒', {    title: '提醒', message: h('div', null, newDatas), showCancelButton: true, confirmButtonText: '跳过', cancelButtonText: '勾销', type: 'warning' }).then(() => {  this.$message('后盾解决中'); uploadPiles(yesPile).then(); //申请二 uploadProgress().then((res) => {    let data = res.data.errcode; console.log(data)  });}).catch(() => {  this.$message('已勾销');});
