el-upload不立即上传文件

1、点击长传文件按钮，上传后将文件保存到FormData中

 <el-upload
  ref="upload"
  :auto-upload="false"
  :action="uploadUrl"
  :file-list="fileList"
  :on-change="handelOnChange"
  :on-remove="handelRemove"
  accept=".xls,.xlsx"
 >
   <el-button type="info">上传文件</el-button>
 </el-upload>

 data() {
   return {
     fileList: [],
     uploadUrl: "",
   } 
 },
 methods:{
   handelOnChange(file, fileList) {
     this.fileList = [file];
     let fd = new FormData();
     fd.append("file", file.raw);
     this.fd = fd;
    },
    handelRemove(response, file, fileList) {
     this.fd = null;
    },
 },  

2、点击确定将this.fd.file的文件作为参数请求接口

  <MORButton style="margin-left: 20px" @click="submit">确定</MORButton>

  submit() {
    let Formdt = new FormData();
    Formdt.append("multipartFile", this.fd.get("file"));
    axios
      .post("url", Formdt, {
        headers: { "Content-Type": "multipart/form-data" },
      })
      .then((res) => {
        if (res.data.code == 0) {
          this.$message.success("保存成功");
        } else {
          this.$alert(res.data.msg, "提示", {
            confirmButtonText: "确定",
          });
        }
      })
      .catch((err) => {});
  },
