Question

Bootstrap提供以下代码用作导航栏。但是，当我只是粘贴代码而不改变它时，折叠的视图不起作用。当您将浏览器窗口调整为更窄时，导航栏将变为一个按钮，您可以单击该按钮再次显示所有导航组件。但是，当我只是粘贴代码时，它似乎无法正常工作。谁知道为什么？导航组件确实已折叠，但单击按钮显示它们并没有做任何事情。

Answer 1

我没有看到你在bootstrap.js文件之前包含jQuery。 jQuery需要使用bootstrap javascript组件。

在您的bootstrap.js文件中添加此config/js.php。

<!-- jQuery (necessary for Bootstrap's JavaScript plugins) -->
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.3/jquery.min.js"></script>

Answer 2

如果我理解你的问题，这就是你想要的：

Jquery的：

$(".navbar-toggle").click(function(){
    $(".navbar").slideToggle();
});
