accept中限制文件類型pdf、doc、docx、 jpg、 png、xls 、xlsx等格式

<input type="file" accept="image/*" />   

accept表示可以上傳文件類型，image表示圖片，*表示所有支持的格式。（ps：wps不適用，所有還是老老實實截取文件類型。）

        if (['xls','xlsx'].indexOf(FileExt.toLowerCase()) === -1){
          this.$message.warning('只能上傳.XLS.XLSX格式的文件!');
          return false;
        }
