我无法更改asp.net母版页模板中的活动页面菜单颜色。我不知道为什么。一切都好，我猜。请查看我的代码并建议我该怎么做。

先谢谢

这是我的site.css

Answer 1

您可能无法更改菜单颜色，因为另一个css会覆盖您的活动菜单样式。如果您的活动菜单样式是：

div.menu ul li a:active
{
    background-color: #bfcbd6;
    color: #bfcbd6;
    text-decoration: none;
}

然后这种风格更强，并会覆盖它：

div.menu ul li a, div.menu ul li a:visited
{
    background-color: #465c71;
    border: 1px #4e667d solid;
    color: #dde4ec;
    display: block;
    line-height: 1.35em;
    padding: 4px 20px;
    text-decoration: none;
    white-space: nowrap;
}

请注意div.menu ul li a：visited表示已访问并且可能已访问活动链接。您应该将其更改为：

div.menu ul li a:active, div.menu ul li a:active:visited
{
    background-color: #bfcbd6;
    color: #bfcbd6;
    text-decoration: none;
}

Answer 2

请记住，每次单击主页面内的菜单项时，都会回发到服务器，并在浏览器中重新绘制新请求的页面。

您可以在母版页的文档加载功能中添加逻辑，以检查用户当前所在的页面，然后找到相应的菜单项并为其设置CSS，这是一个示例：

<style type="text/css">
    .activeMenu {
        border: 2px solid red;
    }
</style>
<script src="Scripts/jquery-1.8.2.js"></script>
<script type="text/javascript">
    $(function () {

        var pageTitle = document.title;

        alert("The user is on page - " + pageTitle);

        $("#menu li").each(function () {

            var menuItemText = $(this).text();

            alert("Menu item - " + menuItemText)

            if (pageTitle == menuItemText)
                $(this).addClass("activeMenu");
        });
    });
</script>

更改活动母版页
