移动端样式下添加二级分类

代码

修改header.php 相关j-sidebar-xs中的部分,主要是替换下面这一部分

        <div class="card">
            <div class="title">类目归类</div>
            <ul class="category-nav">
                <?php while ($categorys->next()) : ?>
                    <?php $children = $categorys->getAllChildren($categorys->mid); ?>
                    <?php if ($categorys->levels === 0): ?>
                        <?php if (empty($children)): ?>
                            <li class='<?php if ($this->is('category', $categorys->slug)) _e("active"); ?>'>

                        <?php endif; ?>
                    <?php endif; ?>
                <?php endwhile; ?>
            </ul>
        </div>

添加js 控制

    $('.j-sidebar-xs .item.category ul li a').unbind().bind('click',function (ev) {
                    let c = $(this);
                    c.parent().siblings(".active").toggleClass("active")
                    if(c.next().is("ul") && c.parent().toggleClass("active") && ev.preventDefault()) return false;
                })

添加css

以下为scss样式

    .item.category{
    ul.category-nav li ul{
        display: none;
        padding-left: 2.5em;
        opacity: 0;
        height: 0;
        overflow: auto;
        -webkit-transition: all .2s ease-in-out 0s;
        transition: all .2s ease-in-out 0s;
        li:last-child{
            border-bottom: none;
        }
    }
    ul.category-nav li a {
        span{
            float: right;
        }
        .text-down{
            display: none;
        }
    }

    ul.category-nav li.active {
        ul {
            display: block;
            opacity: 1;
            height: auto;
        }
        a .text-right{
            display: none;
        }
        a .text-down{
            display: block;
        }
    }
    }
    .j-sidebar-xs .content .item .card ul li {
        display: block; 
    }
