(vue)el-radio鼠标移入可提示图片

效果：

<el-form-item label="图表选择">
  <el-radio-group v-model="formInline.echartType">
    <el-tooltip v-for="(item, index) of echartTypeOptions" :key="index" placement="right" effect="light">
      <div slot="content"><el-image :src="testImg[index]" style="width: 100px; height: 100px" /></div>
      <el-radio :label="item.echartType">
        {{ item.name }}
      </el-radio>
    </el-tooltip>
  </el-radio-group>
</el-form-item>

testImg[index]本应该是item.img,暂代测试

testImg: [
