javascript - Jquery Slide Down 显示带循环的div

Question

我有多个带有嵌套 div 的复杂 div，包括文本和图像。当页面加载时，我显示了 4 个 div。下面显示了一个按钮，其中包含显示更多的选项。每次用户按下显示更多按钮时，我都会使用 Jquery 向下滑动并显示接下来的 2 个 div。总共有 28 个 div，所以它将是 14 行。一旦所有的 div 都可见，按钮将变为“显示较少”，其余的 div 将向上滑动或隐藏(尚未到达这一部分)

出于某种原因，JsFiddle 甚至不能正常工作:(，我不是最擅长 JavaScript 的。下面是代码和 Jsfiddle 链接。我在示例中制作了简单的 div。

给你。

您的 if 在函数之外，所以它不起作用，还进行了更新，以便您可以在它们全部显示后隐藏它们。

我还从 a 标签中删除了 href，因为它导致页面一直向上移动。如果你没有链接，你不应该把 hrefs 放在标签上
