附加 CSS、JS、Bootstrap CDN 版本后，只有一个文件未正确呈现

Question

根据我在 <header> 中附加的库，某些页面上的内容呈现会有所不同。这个错误与版本有关吗？还是别的？

1) 这会禁用页面 A 中的下拉框，但呈现页面 B 的内容样式

<!-- Bootstrap css 4.4.0 -->

2) 这会在页面 A 中启用下拉框，但会为页面 B 呈现无样式的内容

我怎样才能对库进行更改，使两者都能正常工作？

(1) enable drop-down box in Page A (2) render the content on Page B styled

提前致谢:)

Answer 1

我能够自己解决这个问题。我就是这样解决这个问题的。

将jquery库放在第一个，然后，在文件末尾为 css 和 js 附加 bootstrap 库。
