Elementui upload problem, urgent!

the uploaded tag reads like this. 

<el-upload
    class="upload-demo"
    ref="uploadNewFile"
    :action="actionUrl"
    :file-list="fileList"
    :auto-upload="false"
    :on-change="newFileChange"
    :on-remove="removeFile"
    :data="newFileData"
    name="files"
    :on-preview="handlePreview">
    <el-button type="primary" class="button b2 upload">
    <i class="iconfont icon-shangchuan"></i> 
    </el-button>
    <el-input style="display: none" v-model="formData.newFile"></el-input>
</el-upload>

when submitting 

saveIt: function () {
                this.$refs["newAddForm"].validate((valid) => {
                    if(valid){
                        if (this.fileNameCheckFlag) {
                            this.newFileData.dictionaryName = this.formData.fileName;
                            this.newFileData.indexName = this.formData.fileName;
                            this.newFileData.isPublish = false;
                            this.newFileData.menuId = 256;
                            this.$refs["newAddForm"].resetFields();
                            this.zDialog.showAdd = false;
                            this.$refs.uploadNewFile.submit();
                            }
                    }

but when uploading files and submitting them, you need to bring this.newFileData.title (file name) and this.newFileData.sort (file sorting number).
how do you assign the file name and file sorting number when uploading multiple files? Where is the assignment?

Vue.js element-ui

get the file in the newFileChange function and append title and sort
var file = document.querySelector ('[type=file]'); 

       
       
        var formData = new FormData();
  
        formData.append('file', file.files[0]);
        formData.append('title','title')
        formData.append('sort','')
        this.fileList=[];
        this.fileList.push({
            name:file.files[0].name,
        })
       this.file=formData
