JS循环遍历ul中li的点击事件给选中li添加css样式(示例代码)

            <div >
                <label>其他推荐:</label>
                <ul>
                    <li class="other_recommend" id="recommend1">10:21</li>
                    <li class="other_recommend" id="recommend2">10:22</li>
                    <li class="other_recommend" id="recommend3">10:25</li>
                    <li class="other_recommend" id="recommend4">10:28</li>
                    <li class="other_recommend" id="recommend5">10:30</li>
                </ul>
