导航栏不要折叠引导程序 5 css

标签： html css twitter-bootstrap navbar bootstrap-5

我正在用 bootstrap 5 创建一个网站，但我的导航栏不起作用。 当我使用移动设备时，它不会扩展。 我正在学习，这就是为什么我不着急。我只是想了解我在做什么，所以我不会重复同样的错误。 我已经在另一个设计中使用了导航栏，但我不想重做。有人可以帮助我了解我在做什么吗？

Bootstrap 5 使用 data-bs-* 为数据属性名称命名。
更改以下内容：

data-target="#navbarSupportedContent"

为此：

data-bs-target="#navbarSupportedContent"

答案 1 :(得分：1)

在折叠导航栏的按钮中，主要属性标签不存在。使用的主要属性是 data-toggle="collapse" data-target=".nav-collapse"。第二个变化是查看您是否添加了这些链接或添加了来自 https://getbootstrap.com/docs/5.0/getting-started/introduction/

的包

希望我的回答对你有帮助

要使导航栏工作，您需要包含一些 java（即使您不会使用它）。 bootstrap -> get started -> JS 中提供的链接实际上不起作用。

因此，为了让您快速轻松地在此处添加标题。

<head>
  <meta charset="utf-8">
  <title>TinDog</title>
  <link href="https://cdn.jsdelivr.net/npm/bootstrap@5.0.0-beta3/dist/css/bootstrap.min.css" rel="stylesheet" integrity="sha384-eOJMYsd53ii+scO/bJGFsiCZc+5NDVN2yr8+0RDqr0Ql0h+rP48ckxlpbzKgwra6" crossorigin="anonymous">
  <link rel="stylesheet" href="css/styles.css">

</head>

我已经设法用外部 js 文件中的 js 代码解决了这个问题，在关闭 body 标签之前，我已经将这些代码包含在页面上。

以下是我曾经使用并设法解决问题的js代码：

$(document).ready(function(){

  //--Navbar_Toggle_icon--//
  NavItemsStatus = '';
  $('.navbar-toggler-icon').mousedown(function(){
    //---Check if the NavItems are opened, if so then close them, otherwise open them--//
    if((NavItemsStatus == "")|| (NavItemsStatus == undefined)){
      NavItemsStatus = 'on';
      //--Do nothing here as the nav items are sliding down after clicked for the first time--// 
    }else if((NavItemsStatus == "off")){
      NavItemsStatus = 'on';
      $("#navbarNavAltMarkup").show(600); //the id which was called on data-bs-target
    }else{
      NavItemsStatus = 'off';
      $("#navbarNavAltMarkup").hide();
      $("#navbarNavAltMarkup").css('height','0px');
    }
  })

});

因此，对于您的情况，要使用的 ID 是 #navbarSupportedContent。

这是我的通用工作解决方案：

$(document).ready(function(){
  $('a[data-bs-toggle="collapse"]').mouseup(function(){
    var expanded = $(this).attr('aria-expanded');
    if(expanded=="true"){
      setTimeout(() => {
        hide_collapse(this);
      }, 100);
    }
  })
  function hide_collapse(element){
    var aria_control = $(element).attr('aria-controls');
    $("#"+aria_control).removeClass("show");
    $(element).attr('aria-expanded',"false");
  }
});
