ScrollSpy不工作引导

ScrollSpy Not Working Bootstrap

本文关键字：工作 ScrollSpy      更新时间：2023-09-26

大家好，我正在使用引导的滚动间谍。我已经应用了一些高度和溢出来使滚动出现，但是应用后滚动间谍不起作用。我的意思是，当我向上或向下滚动时，导航栏中的链接不会改变 如果我删除我给出的样式，它就会开始工作。这是一个 Jsbin 代码。希望这有帮助，请告诉我我做错了什么 

<body data-spy="scroll" data-target=".navbar" data-offset="50">
<nav class="navbar navbar-inverse navbar-fixed-top">
  <div class="container-fluid">
    <div class="navbar-header">
        <button type="button" class="navbar-toggle" data-toggle="collapse" data-target="#myNavbar">
          <span class="icon-bar"></span>
          <span class="icon-bar"></span>
          <span class="icon-bar"></span>                        
      </button>
      <a class="navbar-brand" href="#">WebSiteName</a>
    </div>
    <div>
      <div class="collapse navbar-collapse" id="myNavbar">
        <ul class="nav navbar-nav">

问题是您通过在包装所有部分的 DIV 中使用style="height:500px;overflow:scroll;"来覆盖 BODY 滚动。

因此，BODY 永远不会滚动。相反，您可以将ScrollSpy放在此包装器DIV上。

<div style="height:500px;overflow:scroll;" data-spy="scroll" data-target="#myNavbar" data-offset="50">
...
</div>

另外，data-target应该#myNavbar...

代码上的工作演示

我认为这是一个错误，试图删除高度并添加最小高度，或者采用另一个div元素并为其提供最大高度：200px或您想要的任何

内容
