Php 我的一颗导航药丸坏了

好的，我有上面的代码，除了上面写着“cap3”的地方，它还在工作。当我点击cap3药丸时，标签内容中没有显示任何内容，我看不出代码中有什么错误。我把它贴在这里，也许有人能比我看得更清楚。

我做了一个jsFiddle，这是有效的。唯一的区别是我用一个字符串替换掉了PHP include

我注意到你的#3的include在它和括号之间有一个空格，其他行没有。我不相信这会有什么不同，但你可以试试

---

基于这个工作示例，我想说您的问题在于view_cap3.php中的代码。

将其也放入

感谢您向我展示我的代码正在工作。我发现我在开头的“header.php”中有这一行。我删除了“id=cap 3”，现在它开始工作了。
