<div

</el-upload>
解决办法：
上传之前:before-upload="beforeUpload"再次判断文件类型
beforeUpload(file) {
console.log(file)
var testmsg=file.name.substring(file.name.lastIndexOf('.')+1)
const extension = testmsg === 'xls'
const extension2 = testmsg === 'xlsx'
// const isLt2M = file.size / 1024 / 1024 < 10
if(!extension && !extension2) {
this.$message({
message: '上传文件只能是 xls、xlsx格式!',
type: 'warning'
});
}
// if(!isLt2M) {
// this.$message({
// message: '上传文件大小不能超过 10MB!',
// type: 'warning'
// });
// }
// return extension || extension2 && isLt2M
return extension || extension2
},
