Question

当我缩小窗口并单击导航切换按钮时，它不起作用。按钮不响应。谁能告诉我这里的问题是什么？

    <nav class="navbar fixed-top navbar-expand-lg navbar-dark">
        <div class="container-fluid">
            <a class="navbar-brand" href="javascript:void(0)">
                <h3 class="my-heading ">SKEWED</h3>
            </a>
            <button class="navbar-toggler navbar-toggler-right" type="button" data-toggle="collapse" data-target="#navbarNav" aria-controls="navbarResponsive" aria-expanded="false" aria-label="Toggle navigation">
                <span class="fa fa-bars mfa-white"></span>
            </button>
            <div class="collapse navbar-collapse" id="navbarResponsive">
                <ul class="navbar-nav ml-auto">
                    <li class="nav-item">
                        <a class="nav-link" href="#home">Home</a>
                    </li>

                    </li>

我为您创建了一个小提琴，是从Bootstrap网站复制的。请参考Bootstrap website。

在您的示例中，您定位到data-target="#navbarNav"。但是您的<div class="collapse navbar-collapse" ID是"navbarResponsive"。将相同的id放入data-target中。这样可以解决您的问题。

欢迎堆栈溢出，您的（data-target =“＃myNavbar”）应该与（id =“ myNavbar”）相同，希望这会有所帮助...

Answer 3

Where is this id that you give to data-target="#navbarNav" .. you are not using this ID anywhere then how the toggle works.. 

 <div class="collapse navbar-collapse" id="navbarResponsive">

相应地进行更改。.因为目标和ID不同。
