我的轮播图片在 Joomla 上消失了。我正在尝试使用 W3 Schools 的以下代码为网页设置自动横幅，我已将代码输入到 Joomla 的自定义模块中。我也试过将它与 Notepad++ 一起使用并在浏览器中打开它，它工作得很好。但是，在 Joomla 页面上图像变白并且不显示。我可以在它们之间切换， slider 和箭头的 CSS 似乎可以正常工作。请找到我的代码:

最佳答案
如果您正在使用自定义 HTML 模块 - 它会禁用您的所有脚本 我建议您使用其他东西在模块中使用 JS - 例如 - Flexi 自定义代码
关于javascript - 在 Joomla 上使用自定义 HTML 轮播消失，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/49875601/
