如何实现radio的显示与隐藏
从数据库中查询出一套单选题,
<?php foreach($list as $k=>$v){ ?> <ul> <li><?php echo $v['id'];?>、<?php echo $v['sub'];?></li> <li><input type="radio" name="<?php echo $k['id'];?>" value="Y" />是</li> <li><input type="radio" name="<?php echo $k['id'];?>" value="N" />否</li> <li><input type="radio" name="<?php echo $k['id'];?>" value="?" />?</li> </ul> <?php } ?>
如上代码是从数据库查询出来后显示在页面的代码,
如何实现,显示的时候只显示一个UL?
当点击radio按钮后,隐藏当前UL,显示下一个UL?
回复讨论(解决方案)
用JQuery就可以轻松实现
给每个ul一个跟$key相关的class 比如 class="ul_".$k
然后给raido一个点击事件当点击时找到其父类中class="ul_"+k的ul,将其隐藏($(".ul_"+k).hide();)并将 class="ul_"k+1的ul显示 $(".ul_"k+1).show();
另外是作为考题的话我推荐用ajax,当前dom只有一道题 选一道就传给后台再发下一道过来.

就跟普通的ajax一样,传个当前题的编号去后台取回下一道题即可 然后将取回的内容替换掉当前的内容

抱歉 那是我扯远了. 用之前说的方法就可以了.
另外,ajax在现在的网站开发中很重要.... 而且特别的简单,半个小时就能学会(JQuery的ajax).
如果有需要你可以先去搜一下先关资料看一看 有什么想法或者问题可以随时交流
