bootstrapnavigation

This article mainly includes three major aspects, please study carefully.

1. Form in the navigation bar
The form in the navigation bar does not use the default class mentioned in the Bootstrap form chapter, it uses the .navbar-form class. This ensures proper vertical alignment of the form and collapse behavior in narrower viewports. Use the alignment options (which are explained in detail in the Component Alignment section) to decide where the content in the navigation bar is placed.

The following example demonstrates this:

<!DOCTYPE html> 
<html> 
<head> 
  <title>Bootstrap 实例 - 默认的导航栏</title> 
  <link href="bootstrap.min.css" rel="stylesheet"> 
  <script src="jquery-2.1.4.min.js"></script> 
  <script src="bootstrap.min.js"></script> 
</head> 
<body> 
<nav class="navbar navbar-default" role="navigation"> 
  <div class="navbar-header"> 
   <a class="navbar-brand" href="#">林炳文在此～</a> 
  </div> 
  <div> 
   <ul class="nav navbar-nav"> 
     <li class="active"><a href="#">导航一</a></li> 
     <li><a href="#">导航二</a></li> 
     <li class="dropdown"> 
      <a href="#" class="dropdown-toggle" data-toggle="dropdown"> 
        下拉菜单 
        <b class="caret"></b> 
      </a> 
      <ul class="dropdown-menu"> 
        <li><a href="#">我是谁呢？</a></li> 
        <li><a href="#">我也不知道</a></li> 
        <li><a href="#">你是谁呢？</a></li> 
        <li class="divider"></li> 
        <li><a href="#">分离的链接</a></li> 
        <li class="divider"></li> 
        <li><a href="#">另一个分离的链接</a></li> 
      </ul> 
     </li> 
   </ul> 
  </div> 
  <div> 
   <form class="navbar-form navbar-left" role="search"> 
     <div class="form-group"> 
      <input type="text" class="form-control" placeholder="Search"> 
     </div> 
     <button type="submit" class="btn btn-default">搜一下</button> 
   </form>   
  </div> 
</nav> 
</body> 
</html>

2. Buttons in the navigation bar
You can use class .navbar-btn to add a button to a

Don’t use .navbar-btn on elements inside .navbar-nav as it is not a standard button class.
The following example demonstrates this:

<!DOCTYPE html> 
<html> 
<head> 
  <title>Bootstrap 实例 - 默认的导航栏</title> 
  <link href="bootstrap.min.css" rel="stylesheet"> 
  <script src="jquery-2.1.4.min.js"></script> 
  <script src="bootstrap.min.js"></script> 
</head> 
<body> 
<nav class="navbar navbar-inverse" role="navigation"> 
  <div class="navbar-header"> 
   <a class="navbar-brand" href="#">林炳文在此～</a> 
  </div> 
  <div> 
   <ul class="nav navbar-nav"> 
     <li class="active"><a href="#">导航一</a></li> 
     <li><a href="#">导航二</a></li> 
     <li class="dropdown"> 
      <a href="#" class="dropdown-toggle" data-toggle="dropdown"> 
        下拉菜单 
        <b class="caret"></b> 
      </a> 
      <ul class="dropdown-menu"> 
        <li><a href="#">我是谁呢？</a></li> 
        <li><a href="#">我也不知道</a></li> 
        <li><a href="#">你是谁呢？</a></li> 
        <li class="divider"></li> 
        <li><a href="#">分离的链接</a></li> 
        <li class="divider"></li> 
        <li><a href="#">另一个分离的链接</a></li> 
      </ul> 
     </li> 
   </ul> 
  </div> 
  <div> 
   <form class="navbar-form navbar-left" role="search"> 
     <div class="form-group"> 
      <input type="text" class="form-control" placeholder="Search"> 
     </div> 
     <button type="submit" class="btn btn-default">搜一下</button> 
   </form>  
   <button type="button" class="btn btn-default navbar-btn"> 
     导航栏按钮 
   </button>    
  </div> 
</nav> 
</body> 
</html>

The effect is as follows:

3. Text in the navigation bar
If you need to include a text string in the navigation, use class .navbar-text. This is typically used in conjunction with the

tag, ensuring appropriate leading and coloring. The following example demonstrates this:

<div class="navbar-header"> 
   <a class="navbar-brand" href="#">林炳文在此～</a>   
  </div> 
  <div> 
   <p class="navbar-text">导航栏中的文本</p> 
  </div> 
  <div>

The effect is as follows:

The above is the entire content of this article. I hope it will be helpful to everyone’s learning, so that everyone can implement the Bootstrap navigation bar more skillfully.

JavaScript in Action: Real-World Examples and ProjectsApr 19, 2025 am 12:13 AM

JavaScript's application in the real world includes front-end and back-end development. 1) Display front-end applications by building a TODO list application, involving DOM operations and event processing. 2) Build RESTfulAPI through Node.js and Express to demonstrate back-end applications.

JavaScript and the Web: Core Functionality and Use CasesApr 18, 2025 am 12:19 AM

The main uses of JavaScript in web development include client interaction, form verification and asynchronous communication. 1) Dynamic content update and user interaction through DOM operations; 2) Client verification is carried out before the user submits data to improve the user experience; 3) Refreshless communication with the server is achieved through AJAX technology.

Understanding the JavaScript Engine: Implementation DetailsApr 17, 2025 am 12:05 AM

Understanding how JavaScript engine works internally is important to developers because it helps write more efficient code and understand performance bottlenecks and optimization strategies. 1) The engine's workflow includes three stages: parsing, compiling and execution; 2) During the execution process, the engine will perform dynamic optimization, such as inline cache and hidden classes; 3) Best practices include avoiding global variables, optimizing loops, using const and lets, and avoiding excessive use of closures.

Python vs. JavaScript: The Learning Curve and Ease of UseApr 16, 2025 am 12:12 AM

Python is more suitable for beginners, with a smooth learning curve and concise syntax; JavaScript is suitable for front-end development, with a steep learning curve and flexible syntax. 1. Python syntax is intuitive and suitable for data science and back-end development. 2. JavaScript is flexible and widely used in front-end and server-side programming.

Python vs. JavaScript: Community, Libraries, and ResourcesApr 15, 2025 am 12:16 AM

Python and JavaScript have their own advantages and disadvantages in terms of community, libraries and resources. 1) The Python community is friendly and suitable for beginners, but the front-end development resources are not as rich as JavaScript. 2) Python is powerful in data science and machine learning libraries, while JavaScript is better in front-end development libraries and frameworks. 3) Both have rich learning resources, but Python is suitable for starting with official documents, while JavaScript is better with MDNWebDocs. The choice should be based on project needs and personal interests.

From C/C to JavaScript: How It All WorksApr 14, 2025 am 12:05 AM

The shift from C/C to JavaScript requires adapting to dynamic typing, garbage collection and asynchronous programming. 1) C/C is a statically typed language that requires manual memory management, while JavaScript is dynamically typed and garbage collection is automatically processed. 2) C/C needs to be compiled into machine code, while JavaScript is an interpreted language. 3) JavaScript introduces concepts such as closures, prototype chains and Promise, which enhances flexibility and asynchronous programming capabilities.

JavaScript Engines: Comparing ImplementationsApr 13, 2025 am 12:05 AM

Different JavaScript engines have different effects when parsing and executing JavaScript code, because the implementation principles and optimization strategies of each engine differ. 1. Lexical analysis: convert source code into lexical unit. 2. Grammar analysis: Generate an abstract syntax tree. 3. Optimization and compilation: Generate machine code through the JIT compiler. 4. Execute: Run the machine code. V8 engine optimizes through instant compilation and hidden class, SpiderMonkey uses a type inference system, resulting in different performance performance on the same code.

Beyond the Browser: JavaScript in the Real WorldApr 12, 2025 am 12:06 AM

JavaScript's applications in the real world include server-side programming, mobile application development and Internet of Things control: 1. Server-side programming is realized through Node.js, suitable for high concurrent request processing. 2. Mobile application development is carried out through ReactNative and supports cross-platform deployment. 3. Used for IoT device control through Johnny-Five library, suitable for hardware interaction.
