vue element InfiniteScroll 无限滚动 入坑记录

   select_law_by_tag()
    {
        this.laws_loading.is_loading = true;

          if(data.last_page <= data.current_page)
          {

        <el-form-item label="法规" prop="synthesis_id" v-loading='laws_loading.is_loading'>
          <div>
            <el-radio-group
              v-model="extractForm.law_id"
              v-infinite-scroll="laws_load"
              class="synthesis_selected"
              size="small"
            >
              <el-radio
                border
                v-for="item in laws"
                :key="item.id"
                :label="item.id"
              >
              {{item.title}}
              </el-radio>
              <p v-if="laws_loading.is_loading" style="text-align: center; height: 1rem; font-size: 0.5rem">加载中...</p>
              <p v-if="laws_loading.no_more" style="text-align: center;height: 1rem; font-size: 0.5rem">没有更多了</p>
            </el-radio-group>

          </div>

        </el-form-item>

　　css 如下

.synthesis_selected {display: block; max-height: 200px; overflow-y: scroll;}
.synthesis_selected .el-radio { margin:0.5rem;}

　　解决下拉失效的问题

主要是 下拉事件不能触发导致，， 解决办法是再 嵌套 触发事件， 保证下拉到底事件触发

最终解决代码

或者  最正确的做法， 刷新组件， 让组件填充container
