网站建设平台加盟纵横seo

总结：平常使用v-for的key都是使用index，这里vue官方文档也不推荐，这个时候就出问题了，我们需要key为唯一标识，这里我使用了时间戳（new Date().getTime()）处理比较复杂的情况，

压缩文件 imageConversion 详见： vue+elementUI 上传图片时压缩图片

<script>
import * as imageConversion from 'image-conversion';
export default {components: {  },data() {return {addList: [{id: 0,uploadDisabled: false,album: '',zip: '',way: 0,idxxx: 0// fileList: [],// fileListZip: []}],}}
}
</script>

删除某一项 idxxx作为唯一标识，因为需求原因 在没添加时间戳(new Date().getTime())之前是没有唯一标识的

//再后面添加一项，idxxx作为唯一标识，因为需求原因 在没添加时间戳之前是没有唯一标识的plusOne() {this.addList.push({id: 0,uploadDisabled: false,album: '',zip: '',way: 0,idxxx: new Date().getTime()})
},
removeOne(index, id, item) {
//使用唯一标识删除this.addList = [...this.addList.filter(e => e.idxxx !== item.idxxx)]
},

下面是其他的上传文件的方法

// 模板图片
beforeUploadOne(file) {console.log(file.size, '压缩前');const isJpgOrPng =file.type === "image/jpeg" || file.type === "image/png";const isLt1M = file.size / 1024 / 1024 < 1;console.log(file.size / 1024 / 1024, 'isLt1M==');if (file.size / 1024 / 1024 > 2 || file.size / 1024 / 1024 == 2) {this.$message.error("上传图片不能超过2M");return false;}if (!isJpgOrPng) {this.$message.error("上传图片只能是 JPG 或 PNG 格式!");return false;}return new Promise((resolve) => {// 小于1M 不压缩// if (isLt1M) {//     resolve(file)// }// 压缩到600KB,这里的600就是要压缩的大小,可自定义imageConversion.compressAccurately(file, 600).then((res) => {console.log(res, '-----res====');resolve(res);});});
},
handlePictureCardPreviewOne(file) {console.log(file, 'file');this.dialogImageUrlOne = file.url;this.dialogVisibleOne = true;
},
handleRemoveOne(file, fileList) {console.log(file, fileList);this.uploadDisabledOne = false;
},
handleAvatarSuccessOne(res, file) {console.log(res, file, 'res, file');this.dialogImageUrlOne = res.data.fullurlconsole.log(this.dialogImageUrlOne, 'this.dialogImageUrlOne图片路径');
},
uploadSectionFileOne(file, fileList) {if (fileList.length >= 1) {this.uploadDisabledOne = true;}
},

// zip
handleRemoveZip(file, fileList) {console.log(file, fileList, '移走路径');
},
handleAvatarSuccessZip(obj, res, file) {console.log(res, file, 'res, file111');console.log(res.data.fullurl, '压缩包路径')this.zip_file = res.data.fullurllet imgList = this.addListlet index = obj.index;this.addList[index].zip = res.data.fullurl},
