表单中提交可选择的图片上传【el-radio+v-img】

1.新增图片：单选按钮+图片展示

 <el-form-item label="项目icon" prop="iconImg">
          <el-radio-group v-model="projectModel.icon" class="radioImg">
            <el-radio v-for="it in iconList" :label="it.name" border style="height: 52px ; 52px">
              <v-img height="50" width="50" :src="it.icon" :key="it.name"></v-img>
            </el-radio>
          </el-radio-group>     
 </el-form-item>

2.主要进行样式调整，代码如下：

  .radioImg .el-radio__input {
    display: none;
  }
  .radioImg .el-radio__inner {
    display: none;
  }
  .radioImg .el-radio .is-bordered {
    padding: 0px;
  }
  .radioImg .v-image {
    border-radius: 4px;
  }
  .radioImg .el-radio {
    margin: 10px;
  }
  .radioImg .el-radio__label div {
    margin: -26px 0px 0px -10px;
  }
  .radioImg .el-radio__label .v-image__image {
    margin: 0;
  }
  .radioImg .el-radio.is-bordered + .el-radio.is-bordered {
    margin: 10px;
  }

3.获取icon列表展示代码：【注意后端给的是二进制流图片，需要前面加上字符串"data:image/png;base64," 才能展示成功】

 //获取icon列表
      async getIcon() {
        let { data } = await getIcon()
        for (let item of data) {
          for (let [key, val] of Object.entries(item)) {
            let obj = {
              name: key,
              icon: "data:image/png;base64," + val
            }
            this.iconList.push(obj)
          }
        }
      }

4.最后保存成功后列表里展示图片

展示代码如下：

<el-table-column prop="icon" label="项目icon" align="center">
      <template slot-scope="scope">
            <img :src='"data:image/png;base64,"+scope.row.iconContent' alt="" style=" 40px;height: 40px">
      </template>
</el-table-column>
