jquery - 在页面上时突出显示选定的菜单项

Question

所以这让我疯狂了一整天，我只想在相应页面上突出显示当前 li，

请原谅我的困惑，但这是我的代码，

HTML

<div id="layout">
        <!-- Menu toggle -->
        <a href="#menu" id="menuLink" class="menu-link active">
            <span></span>
        </a>
        <div id="menu">
            <div class="pure-menu pure-menu-open">
                <a class="pure-menu-heading" href="pure.html">Nathaniel Harman</a>
                <ul class="nav">
                    <li>
                        <a href="software.html">
                            <span class="icon-macintosh" style="vertical-align: middle"></span>SOFTWARE</a>
                    </li>
                    <li>
                        <a href="frameworks.html">
                            <span class="icon-painting-roll-streamline" style="vertical-align: middle"></span>FRAMEWORKS</a>
                    </li>
                    <li>
                        <a href="lang.html">
                            <span class="icon-ink-pen-streamline" style="vertical-align: middle"></span>LANGUAGES</a>
                    </li>
                    <li>
                        <a href="projects.html">
                            <span class="icon-crop-streamline" style="vertical-align: middle"></span>PROJECTS</a>
                    </li>
                    <li>
                        <a href="exp.html">

                    </li>
                    <li>
                        <a href="production.html">
                            <span class="icon-design-graphic-tablet-streamline-tablet" style="vertical-align: middle"></span>IN PRODUCTION</a>
                    </li>
                    <li>
                        <a href="development.html">
                            <span class="icon-barista-coffee-espresso-streamline" style="vertical-align: middle"></span>IN DEVELOPMENT</a>
                    </li>
                    <li>
                        <a href="contact.html">
                            <span class="icon-map-streamline-user" style="vertical-align: middle"></span>CONTACT</a>
                    </li>
                </ul>

CSS

#menu {
    margin-left: -200px; /* "#menu" width */
    width: 200px;
    position: fixed;
    top: 0;
    left: 0;
    bottom: 0;
    z-index: 1000; /* so the menu or its navicon stays above all content */
    background: #191818;
    overflow-y: auto;
    -webkit-overflow-scrolling: touch;
}

    #menu a {
        color: #999;
        border: none;
        padding: 0.6em 0 0.6em 0.6em;
    }


     #menu .pure-menu,
     #menu .pure-menu ul {
        border: none;
        background: transparent;
    }


    #menu .pure-menu ul,
    #menu .pure-menu .menu-item-divided {
        border-top: 1px solid #333;
    }

        #menu .pure-menu li a:hover,
        #menu .pure-menu li a:focus,
        #menu .pure-menu span:hover{
            background: #333;
            color:#fff;
        }


    #menu .pure-menu-selected,
    #menu .pure-menu-heading {
        background: #909090;
    }
           #menu .pure-menu-selected a {
            color: #fff;
        }

    #menu .pure-menu-heading {
        font-size: 110%;
        color: #fff;
        margin: 0;
    }

.menu-link {
    position: fixed;
    display: block; /* show this only on small screens */

    left: 0; /* "#menu width" */
    background: #000;
    background: rgba(0,0,0,0.7);
    font-size: 10px; /* change this value to increase/decrease button size */
    z-index: 10;
    width: 2em;
    height: auto;
    padding: 2.1em 1.6em;
}

    .menu-link:hover,
    .menu-link:focus {

    }

    .menu-link span {
        position: relative;
        display: block;
    }

    .menu-link span,
    .menu-link span:before,
    .menu-link span:after {
        background-color: #fff;
        width: 100%;
        height: 0.2em;
    }

        .menu-link span:before,
        .menu-link span:after {
            position: absolute;
            margin-top: -0.6em;
            content: " ";
        }

        .menu-link span:after {
            margin-top: 0.6em;
        }

任何帮助都会很棒我不知道我哪里出错了，正如你所看到的我正在使用纯 CSS 框架

Answer 1

最简单的方法是创建一个类，假设为 current，并将其分配给每个单独页面上的 li 元素。例如，您的 software.html 文件将如下所示:

<li class="current">
    <a href="software.html">
        <span ...></span>SOFTWARE</a>
</li>
<li>
    <a href="frameworks.html">
        <span ...></span>FRAMEWORKS</a>
</li>

虽然您的 frameworks.html 文件看起来像这样:

<li>
    <a href="software.html">
        <span ...></span>SOFTWARE</a>
</li>
<li class="current">
    <a href="frameworks.html">
        <span ...></span>FRAMEWORKS</a>
</li>

然后根据 .current 设置相应的样式
