javascript - 如何使用javascript控制标签当前效果

Question

我有一个 html 表单，其中包含一个标签菜单，代码是

<ul id="menu">
    <li><a href="f?p=&APP_ID.:1:&SESSION.:" class="active">Home</a></li>
    <li>
        <a href="f?p=&APP_ID.:400:&SESSION.:" class="current">Leave Eligibility</a>

    </li>
    <li><a href="f?p=&APP_ID.:450:&SESSION.:" class="current2">Apply Leave</a></li>
    <li><a href="f?p=&APP_ID.:300:&SESSION.:" class="current3">Change Password</a></li>
    <li><a href="f?p=&APP_ID.:11:&SESSION.:" class="current4">Applied Leaves</a></li>
        <li><a href="f?p=&APP_ID.:25:&SESSION.:" class="current4">Holidays</a></li>
        <li><a href="f?p=&APP_ID.:445:&SESSION.:" class="current4">Contact</a></li>
</ul>

这个html的css是

#menu{

    margin: 0;
    padding: 10px 0 0 0;
    list-style: none;
    background: #111;
    background: -moz-linear-gradient(#444, #111);

/* Clear floated elements */

    content: " ";
    clear: both;
    height: 0;

* html #menu             { zoom: 1; } /* IE6 */

    }

因此默认情况下，主页选项卡在页面加载时悬停。 当我单击离开资格选项卡时，主页选项卡的悬停效果将被禁用并且 休假资格选项卡将悬停。 我想用 javascript/jquery 来控制它。 所以任何人都请告诉我该怎么做。

如果您使用的是记事本，请尝试使用代码段。

在你的主页上设计应该是这样的

    <li><a href="f?p=&APP_ID.:1:&SESSION.:" class="active">Home</a></li>
    <li>
        <a href="f?p=&APP_ID.:400:&SESSION.:" class="current">Leave Eligibility</a>

    </li>

在您的休假资格页面上

 <li><a href="f?p=&APP_ID.:1:&SESSION.:" class="current">Home</a></li>
    <li>
        <a href="f?p=&APP_ID.:400:&SESSION.:" class="active">Leave Eligibility</a>

    </li>

其他页面依此类推。

我把它放在你的快速引用...

试试这个

$("a").live('click', function() {
  $("a").removeClass("active");
  $(this).addClass("active");
  return false;
});
