我尝试通过更改“head”元素内的顺序在 jquery-bootstrap 脚本之前加载 jquery-source 脚本，但它没有用，另外，我确保链接 bootstrap CSS 文件。
我看了一下bootstrap default navbar example并且似乎一切正常但仍然无法正常工作？
最后，我用的是JSF-2.2框架，不知道和这个问题有没有关系？这是完整的代码

最佳答案
使用“src”属性代替“library”和“name”jsf 的属性解决了这个问题。
我发现原因是因为我在脚本标签内使用了 (jsf:libray=""and jsf:name="")。!
生成的 HTML 文件具有无效的 javascript 文件 URL，这意味着没有脚本在运行。
