}

     deletePic(event) {this.scoreFileList.splice(event.index, 1)},// 新增图片async afterRead(event) {let lists = [].concat(event.file);let fileListLen = this.scoreFileList.length;lists.map((item) => {this.scoreFileList.push({...item,status: "uploading",message: "上传中",});});for (let i = 0; i < lists.length; i++) {const result = await this.uploadFilePromise(lists[i].url);let item = this.scoreFileList[fileListLen];this.scoreFileList.splice(fileListLen,1,Object.assign(item, {status: "success",message: "",url: result,}));fileListLen++;}},uploadFilePromise(url) {return new Promise((resolve, reject) => {uni.uploadFile({url: 'http://www.example.com/upload', // 仅为示例，非真实的接口地址filePath: url,name: "file",success: (uploadFileRes) => {let res = JSON.parse(uploadFileRes.data);resolve(res.message);},fail: (err) => {console.log(err);},});});},
