Question

我想通过javascript使用div class INSIDE来突出显示当前菜单项。在第一次尝试中，我刚刚添加了课程＆＃34; top-bar-underline＆＃34;到a-tag，但由于菜单项是＆＃34; display：block;＆＃34;这样下划线超出了菜单项的字体，我将下划线放在a-tag内的div-container中。对于悬停效果，这非常合适。

问题：

如何添加课程＆＃34; top-bar-underline-current＆＃34;上课＆＃34;顶栏 - 下划线＆＃34;对于当前活动菜单项？

我目前的代码如下：

html菜单：

<ul class="right">                
                <li>
                    <a href="{{ site.url }}"><div class="top-bar-underline">LATEST</div></a>
                </li>
                <li>
                    <a href="{{ site.url }}/pages/about/"><div class="top-bar-underline">ABOUT</div></a>
                </li>

</ul>

js突出显示菜单中的当前a：

<script type="text/javascript">
var url = window.location.href;
$('.top-bar-section li:not(.has-form) a:not(.button)').filter(function() {
    return this.href == url;
}).addClass('top-bar-underline-current');
</script>

的CSS：

.top-bar-underline {
position: relative;
color: #ff3296;
}
.top-bar-underline:after {
display: block;
position: absolute;
top: 70%;
left: 0;
width: 100%;
height: 2px;
background: rgba($body-font-color,0.9);
content: '';
opacity: 0;
-webkit-transition: opacity 0.2s, -webkit-transform 0.2s;
-moz-transition: opacity 0.2s, -moz-transform 0.2s;
transition: opacity 0.2s, transform 0.2s;
-webkit-transform: translateY(10px);
-moz-transform: translateY(10px);
transform: translateY(10px);
}
.top-bar-underline:hover {
color: #98004a;

}
.top-bar-underline:hover:after,
.top-bar-underline:focus:after {
 width: 100%;
 opacity: 1;
-webkit-transform: translateY(0px);
-moz-transform: translateY(0px);
transform: translateY(0px);
}
.top-bar-underline-current {
position: relative;
}
.top-bar-underline-current:after {
position: absolute;
top: 70%;
left: 0;
width: 100%;
height: 2px;
background: rgba($body-font-color,0.9);
content: '';
opacity: 1;
-webkit-transition: opacity 0.2s, -webkit-transform 0.2s;
-moz-transition: opacity 0.2s, -moz-transform 0.2s;
transition: opacity 0.2s, transform 0.2s;
-webkit-transform: translateY(0px);
-moz-transform: translateY(0px);
transform: translateY(0px);
}
.top-bar-underline-current:hover:after,
.top-bar-underline-current:focus:after {
width: 100%;
opacity: 1;
-webkit-transform: translateY(0px);
-moz-transform: translateY(0px);
transform: translateY(0px);
}

感谢您的帮助！

var url = window.location.href;
$('.top-bar-section li:not(.has-form) a:not(.button)').filter(function() {
    return this.href == url;
}).find('.top-bar-underline').addClass('top-bar-underline-current');

我认为这就是你需要的......
