让我换一种方式问这个问题:根据我想更新主菜单中使用的图像的 url。
我正在尝试执行以下操作(我的 JavaScript 是废话)
urlPath = document.location.href;
<td>
<script type="text/javascript">
if (urlPath=="mydomain.com/home/")
{
document.write("<img src='current_page.jpg'/>");
}else{
document.write("<img src='image/normal_button.jpg'/>");
}
</script>
</td>
然后我可以对每个菜单项都这样做。那会起作用还是有更好的方法呢?
以下是我最终必须更新的当前代码。
