javascript - 移动导航在 Ajax 加载后停止工作

好的,所以我在加载 ajax 后打开移动导航时遇到问题。当没有 ajax 加载时,菜单工作完美。当页面最初加载时,菜单会工作,但在单击链接并加载新页面内容后,当我单击它时菜单将不会重新打开。 (控制台中没有出现任何错误。)

在浏览器中检查 html 代码时,我注意到由于某种原因加载 ajax 后,单击导航触发器时它将不再将 nav-open 类应用于标题,这是揭示导航的东西。

我觉得我需要的只是修复 javascript 中的某些内容,但我不确定是什么导致它崩溃。 (为了深入了解 app.js,它设置为最初运行页面脚本,然后在加载 ajax 后再次运行它们。所有脚本都正常运行,页面都运行完美,除了这个移动 -导航问题。)

任何人都可以给我的任何帮助或见解将不胜感激。

最佳答案

感谢 Shilly 和 Andrei Gheorghiu,我设法解决了这个问题。

由于我的导航功能在初始页面加载时运行并在每次 ajax 加载时重新运行,这导致事件运行两次,因此它仅适用于所有其他链接点击.我将导航功能移到 ajax 加载脚本之外,以便它仅在初始页面加载时运行,现在可以正常运行。
