View UI（iView） Upload 自定义多图上传列表提交

iView Upload 自定义多图上传列表提交

可以自由控制上传列表，完成各种业务逻辑，示例是一个照片墙，可以查看大图和删除。

• 设置属性?show-upload-list?为 false，可以不显示默认的上传列表。
• 设置属性?default-file-list?设置默认已上传的列表。

• 通过?on-success?等属性来控制完整的上传过程，详见API。另外，可以通过丰富的配置，来定制上传需求，本例中包含了：

• 文件必须是 jpg 或 png 格式的图片。

• 最多上传5张图片。
• 每个文件大小不超过 2M。

• <div class="upload-list" v-for="item in uploadList">
      <div v-if="item.status === 'finished'"> 
          <img :src="item.url"><div class="upload-list-cover">
              <Icon type="ios-eye-outline" @click.native="handleView(item.url)"></Icon>
              <Icon type="ios-trash-outline" @click.native="handleRemove(item)"></Icon>
      </div>
  </div>
      <div v-else>
          <Progress v-if="item.showProgress" :percent="item.percentage" hide-info></Progress>                         </div>
  </div>
  <Upload
  ref="upload"
  :show-upload-list="false"
  :default-file-list="defaultList"
  :on-success="handleSuccessImgUrl"
  :format="['jpg','png','gif']"
  :max-size="2048"
  :on-format-error="handleFormatError"
  :on-exceeded-size="handleMaxSize"

  </div>

上传操作并更新上传图片列表

<script>   
 export default {   
     data () {    
        return {   
                defaultList: [
                 {
                     'name': 'a42bdcc1178e62b4694c830f028db5c0',                                                                        
                      'url': 'a42bdcc1178e62b4694c830f028db5c0.jpg'       
                 },                
                 {                     
                   'name': 'bc7521e033abdd1e92222d733590f104',
                   'url': 'bc7521e033abdd1e92222d733590f104.jpg'                    
                 }                
               ], 
               imgName: '', 
               visible: false,
               uploadList: []  
          }      
    },    
    methods: {
            handleView (name) {
                this.imgName = name;
                this.visible = true;
            }, 
           handleRemove (file) { 
               const fileList = this.$refs.upload.fileList;              

                this.$refs.upload.fileList.splice(fileList.indexOf(file), 1); 
           },   
           handleSuccess (res, file) { 
               file.url = res.data;            
              },
            handleFormatError (file) { 
               this.$Notice.warning({
                    title: 'The file format is incorrect',
                    desc: 'File format of ' + file.name + ' is incorrect, please select jpg or png.'                
                });            
            }, 
           handleMaxSize (file) {
                this.$Notice.warning({
                    title: '超出文件大小限制',
                    desc: '文件  ' + file.name + ' 太大, 不要超过 2M.'
                });
            },
            handleBeforeUpload () {
                const check = this.uploadList.length < 5;
                if (!check) {
                    this.$Notice.warning({
                        title: '最多可上传5张图片.'
                    });
                }
                return check;
            }
        },
        mounted () { 
           this.uploadList = this.$refs.upload.fileList;        
        }    
}</script>

后台保存提交上传图片的列表

imgUrl: JSON.stringify(this.uploadList),

PHP后台接收保存到数据库

$_imgUrl =json_decode(input('post.imgUrl'),true);

if (is_array($_imgUrl)) {
     for ($i=0; $i < count($_imgUrl); $i++) {
         $imgUrl .= $_imgUrl[$i]['url'].",";     
        }
}
$imgUrl=substr($imgUrl,0,strlen($imgUrl)-1);

重新编辑时加载upload图片获取显示列表

imgUrl = itemInfo.img_url.split(",");
for(var i = 0; i < imgUrl.length; i++) {
    _this.uploadList.push({
      name:'',
      url:imgUrl[i],
      showProgress: false,
      status: "finished"
    });}
