javascript - 附加内容没有获得正确的 CSS 样式

Question

新附加内容的设计与现有内容不同。

这里是我的完整代码:

HTML

<!-- Top Bar -->
<nav class="navbar">
    <div class="container-fluid">


        <div class="collapse navbar-collapse" id="navbar-collapse">
            <ul class="nav navbar-nav navbar-right">


                <!-- Notifications -->

});

一个真实的例子来测试它并查看我的问题:

重现我的问题:

• 点击 Append it 链接

• 然后单击“通知”下拉菜单并向下滚动到最后一个 <li>行，你会发现附加行的设计与其他行不同。

请帮忙解答一下

Answer 1

当您追加新元素时，您缺少了几个类。 a原始元素中的标签具有 waves-effect和 waves-block已应用类，但您没有在新添加的元素中提供这些类。

尝试更改 "<a href=\"javascript:void(0);\">"至 "<a href=\"javascript:void(0);\" class=\" waves-effect waves-block\">"
