Bootstrap 导航栏无法正常工作:AngularCLI [英] Bootstrap Navbar not working correctly: AngularCLI

问题描述

我将引导程序包含在我的 angularcli 项目中，但是当我尝试包含导航栏时，所有元素都无法正常工作.我正在使用网站上的标准 boostrap 导航栏示例，但它看起来很奇怪:

我的项目有什么问题导致导航栏无法正确加载?

navbar.component.html

<nav class="navbar navbar-toggleable-md navbar-light bg-faded"><button class="navbar-toggler navbar-toggler-right" type="button" data-toggle="collapse" data-target="#navbarSupportedContent" aria-controls="navbarSupportedContent" aria-expanded="false" aria-label="切换导航"><span class="navbar-toggler-icon"></span><a class="navbar-brand" href="#">Navbar</a><div class="collapse navbar-collapse" id="navbarSupportedContent"><ul class="navbar-nav mr-auto"><li class="nav-item active"><a class="nav-link" href="#">首页 <span class="sr-only">(当前)</span></a><li class="nav-item"><a class="nav-link" href="#">Link</a><li class="nav-item"><a class="nav-link disabled" href="#">Disabled</a><form class="form-inline my-2 my-lg-0"><input class="form-control mr-sm-2" type="text" placeholder="Search"><button class="btn btn-outline-success my-2 my-sm-0" type="submit">搜索</button></表单>

</nav>

.angular-cli.json

"styles": ["../node_modules/bootstrap/dist/css/bootstrap.min.css",样式.css"],

解决方案

bootstrap 4 中存在一些已知问题，尤其是导航栏实现

因此你必须安装 bootstrap bootstrap@3.3.7

如果您使用的是 npm，那么最好推荐以下库

 npm install bootstrap@3.3.7 --savenpm install bootstrap@3.3.7 tether jquery --save

在 .angular-cli.json 文件中添加依赖

"样式":["styles.css",../node_modules/bootstrap/dist/css/bootstrap.css"],脚本":["../node_modules/jquery/dist/jquery.js","../node_modules/tether/dist/js/tether.js",../node_modules/bootstrap/dist/js/bootstrap.js"],

使用以下 HTML

 
<div class="容器"><div class="navbar-header"><button type="button" class="navbar-togglecollapsed" data-toggle="collapse" data-target="#navbar" aria-expanded="false" aria-controls="navbar"><span class="sr-only">Togglenavigation</span><span class="icon-bar"></span><span class="icon-bar"></span><span class="icon-bar"></span><a class="navbar-brand" href="#">Angular5Website</a>

<div id="navbar" class="collapsenavbar-collapse"><ul class="navnavbar-nav">

<a href="#">首页</a></li><li><a href="#about">关于</a></li><li><a href="#contact">联系方式</a></li></div><!--/.nav-collapse-->

</nav>

I included bootstrap into my angularcli project but when I try to include a navbar none of the elements are working correctly. I am using a standard boostrap navbar example from the website but it looks weird:

What is wrong with my project that is making the navbar not load correctly?

navbar.component.html

<nav class="navbar navbar-toggleable-md navbar-light bg-faded">
  <button class="navbar-toggler navbar-toggler-right" type="button" data-toggle="collapse" data-target="#navbarSupportedContent" aria-controls="navbarSupportedContent" aria-expanded="false" aria-label="Toggle navigation">
    <span class="navbar-toggler-icon"></span>
  </button>
  <a class="navbar-brand" href="#">Navbar</a>

  <div class="collapse navbar-collapse" id="navbarSupportedContent">
    <ul class="navbar-nav mr-auto">
      <li class="nav-item active">
        <a class="nav-link" href="#">Home <span class="sr-only">(current)</span></a>
      </li>
      <li class="nav-item">
        <a class="nav-link" href="#">Link</a>
      </li>
      <li class="nav-item">
        <a class="nav-link disabled" href="#">Disabled</a>
      </li>
    </ul>
    <form class="form-inline my-2 my-lg-0">
      <input class="form-control mr-sm-2" type="text" placeholder="Search">
      <button class="btn btn-outline-success my-2 my-sm-0" type="submit">Search</button>
    </form>
  </div>
</nav>

.angular-cli.json

"styles": [
        "../node_modules/bootstrap/dist/css/bootstrap.min.css",
        "styles.css"
      ],

解决方案

There are some known issues in bootstrap 4 especially in navbar implemenation

Hence uou have to install bootstrap bootstrap@3.3.7

if you are using npm then the following libraries is best recommonded

 npm install bootstrap@3.3.7 --save

npm install bootstrap@3.3.7 tether jquery --save

In .angular-cli.json file add the dependencies

"styles":[
"styles.css",
"../node_modules/bootstrap/dist/css/bootstrap.css"
],

"scripts":[
"../node_modules/jquery/dist/jquery.js",
"../node_modules/tether/dist/js/tether.js",
"../node_modules/bootstrap/dist/js/bootstrap.js"
],

Use the following HTML

 <nav class="navbarnavbar-inverse">
    <div class="container">
    <div class="navbar-header">
    <button type="button" class="navbar-togglecollapsed" data-toggle="collapse" data-target="#navbar" aria-expanded="false" aria-controls="navbar">
    <span class="sr-only">Togglenavigation</span>
    <span class="icon-bar"></span>
    <span class="icon-bar"></span>
    <span class="icon-bar"></span>
    </button>
    <a class="navbar-brand" href="#">Angular5Website</a>
    </div>
    <div id="navbar" class="collapsenavbar-collapse">
    <ul class="navnavbar-nav">
    <li class="active"> <a href="#">Home</a></li>
    <li><a href="#about">About</a></li>
    <li><a href="#contact">Contact</a></li>
    </ul>
    </div><!--/.nav-collapse-->
    </div>
    </nav>
