axios同步及异步加载

注意区别在于“async ” 及“await ”关键词
同步

async getfiles() {
   	var result={};
   	var param = new URLSearchParams()
       param.append('id', $("#type").val())
       var url = "/backstage/fileupload/getFileName.action";
   	await axios.post(url, param).then(function (res) {
           if (res.status == 200) {
           	result=res.data.data;
           } else {
               alert("获取失败！");
           }
       });
   	this.filenames=result
   },

异步

getfiles() {
       	var result={};
       	var param = new URLSearchParams()
           param.append('id', $("#type").val())
           var url = "/backstage/fileupload/getFileName.action";
       		axios.post(url, param).then(function (res) {
               if (res.status == 200) {
               	result=res.data.data;
               } else {
                   alert("获取失败！");
               }
           });
       	this.filenames=result
       },
