el-upload 上传图片

第一：看看页面效果.

 上传图片后效果如下：

 第二步：页面代码：

          <el-row>
                <el-col :span="24">
                  <el-form-item label-width="120px" label="封面图:" class="postInfo-container-item">
                    <el-upload
                      :action="uploadImgsAction()"
                      list-type="picture-card"
                      :limit="1"
                      :on-success="handleVideoSuccess"
                      :on-preview="handlePictureCardPreview"
                      :on-remove="handleRemove">
                      <i class="el-icon-plus"></i>
                    </el-upload>
                    <el-dialog :visible.sync="dialogVisible">
                      <img width="100%" :src="dialogImageUrl" alt="">
                    </el-dialog>
                  </el-form-item>
                </el-col>
              </el-row>

　　截图说明下：

 我这里是请求后台上传图片接口后会返回上传后的图片地址，整个界面的代码(这个是添加页面，里面用到了上传图片)

 添加界面的代码结束了。若需要修改界面，还要展示之前上传的图片

    showAnnouncement(id) {
      this.listLoading = true
      // console.log(this.listQuery)
      GetAnnouncementById({
        id:id
      }).then(response => {
        console.log("clj",response)
        this.listLoading = false
        if(response.code == 200){

          this.postForm = response.data
          this.dialogVisible=true
          //this.dialogImageUrl =response.data.picture;

          var aa = response.data.picture
            var item = {
              name:'imagesName',
              url:aa
            }
            this.fileList.push(item)
          }

      }).catch(function(reason) {
        // that.listLoading = false
        // that.list = null
        // console.log('catch:', reason);
      })
    },
