IE8中的JS不兼容问题

Question

<script language="javascript" type="text/javascript">    var showing = 1;
function show(num) {
   if(showing != num) {
      document.getElementById("articles" + showing).style.display = "none";
      document.getElementById("articles" + num).style.display = "";
          var lis = document.getElementById("category").getElementsByTagName("li");
          lis[showing - 1].className = "";
          lis[num - 1].className = "selected";
      showing = num;
   }
   return false;
}</script>
在IE7下正常，请高手帮忙了，多谢！

Answer 1

          lis[showing - 1].className = "";
          lis[num - 1].className = "selected";
改成：
          lis[showing - 1].setAttribute("class","");
          lis[num - 1].setAttribute("class"，"selected");
试试看。太难猜了，可能是别的地方出问题了，lz给个较全的代码吧

Answer 2

JS代码全了 <div class="title">
        <ul class="category" id="category">
          <li class="selected"><a href="#" onmouseover="show(1)">新闻</a></li>
          <li><a href="#" onmouseover="show(2)">财经</a></li>
        </ul>
      </div>
<div id="articles1 class="clearfix"">
</div>
<div id="articles2" class="clearfix">
</div>
<div id="articles3" class="clearfix">
</div>
<div id="articles4" class="clearfix">
</div>

楼主ie8我试了是好的哟， 你的html里div的id少了个引号~ <div id="articles1 class="clearfix"">
</div>
