已經獲取到upload上傳的文件名, 但是不知道從哪里把文件名的值放在數據類型input的value中html      <div class="data_type">        數據類型:        <div class="import_type_input">          <el-input v-model="input" :value="this.file.name"></el-input>          <el-upload class="upload-demo" ref="upload" name="excelFile" :action="this.uploadFile" :on-preview="handlePreview" :on-change="handleChange" :auto-upload="false" fa:on-remove="handleRemove" :file-list="fileList" :on-success="uploadSuccess" :data="{type: type}">            <el-button size="small" type="primary">選擇Excel數據文件</el-button>          </el-upload>        </div>      </div>js    submitForm() {      console.log('this.file',this.file);    },在點擊提交的時候打印上傳文件名
