This article will learn how to create collapsible components through Bootstarp. The specific content is as follows
What is required
You must reference jquery.js and bootstrap-collapse.js - both JavaScript files are located in the docs/assets/js folder.
You can create collapsible components without writing a lot of JavaScript or calling JavaScript.
Example
The first example demonstrates how to create a collapsible component without calling JavaScript.

<!DOCTYPE html>
<html>
<head>
  <meta charset="utf-8" />
  <title>collapsible example</title>
  <link href="../twitter-bootstrap/twitter-bootstrap-v2/docs/assets/css/bootstrap.css" rel="stylesheet" type="text/css" />

</head>
<body>
  <div class="container-fluid">
   <div class="accordion" id="accordion2">
      <div class="accordion-group">
       <div class="accordion-heading">
        <a class="accordion-toggle" data-toggle="collapse" data-parent="#accordion2" href="#collapseOne">
         Click me to exapand. Click me again to collapse. Part I.
        </a>
       </div>
       <div id="collapseOne" class="accordion-body collapse" style="height: 0px; ">
        <div class="accordion-inner">

      <div class="accordion-group">
       <div class="accordion-heading">
        <a class="accordion-toggle" data-toggle="collapse" data-parent="#accordion2" href="#collapseTwo">
         Click me to exapand. Click me again to collapse. Part II.
        </a>
       </div>
       <div id="collapseTwo" class="accordion-body collapse">
        <div class="accordion-inner">

      <div class="accordion-group">
       <div class="accordion-heading">
        <a class="accordion-toggle" data-toggle="collapse" data-parent="#accordion2" href="#collapseThree">
         Click me to exapand. Click me again to collapse. Part III.
        </a>
       </div>
       <div id="collapseThree" class="accordion-body collapse">
        <div class="accordion-inner">
         Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua.

     </div>
  </div>
 <script type="text/javascript" src="/twitter-bootstrap/twitter-bootstrap-v2/docs/assets/js/jquery.js"></script>
 <script type="text/javascript" src="/twitter-bootstrap/twitter-bootstrap-v2/docs/assets/js/bootstrap-collapse.js"></script>
</body>
</html>

Explanation
There are three points to note here. First, add data-toggle="collapse" to the link you want to click to expand or collapse the component.
Second, add an href or a data-target attribute to the parent component whose value is the id of the child component.
Third, add a data-parent attribute to create an accordion effect. The value of the data-parent attribute is the same as the value of the id attribute of the main container div (which holds the entire accordion component). If you want to create a simple accordion component that doesn't need to be as complex as an accordion, you don't need to add this property.
Example
The second example shows how to create a simple collapsible component.

<!DOCTYPE html>
<html>
<head>
  <meta charset="utf-8" />
  <title>collapsible via JavaScript example</title>
  <link href="/twitter-bootstrap/twitter-bootstrap-v2/docs/assets/css/bootstrap.css" rel="stylesheet" type="text/css" />
</head>
<body>
<div id="myCollapsibleExample"><a href="#demo" data-toggle="collapse">Click me to expand and click me again to collapse.</a></div>
<div id="demo" class="collapse">
Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea commodo consequat. Duis aute irure dolor in reprehe.
</div>
<script type="text/javascript" src="/twitter-bootstrap/twitter-bootstrap-v2/docs/assets/js/jquery.js"></script>
<script type="text/javascript" src="/twitter-bootstrap/twitter-bootstrap-v2/docs/assets/js/bootstrap-collapse.js"></script>
</body>
</html>

Call via JavaScript
You can use the code below to trigger collapse via JavaScript.

 $(".collapse").collapse()

Options, methods and events
Here are some options, methods, and events available through the Bootstrap Collapsible JavaScript plugin. The details are as follows:
Options
parent:The value type is Selector. The default value is false. When the parent element is displayed, all collapsible elements under the parent element are closed.
toggle:The value is of type Boolean. The default value is true. When called, toggle all collapsible elements.
toggle:The value is of type Boolean. The default value is true. When called, toggle all collapsible elements.
Method
.collapse(options): Trigger collapsible content. Accepts an optional option object.
.collapse('toggle'): Show or hide a collapsible page element.
.collapse('show'): Displays a collapsible page element.
.collapse(hide): Hide a collapsible page element.
Event
show: This event is triggered immediately after the show instance method is called.
shown: This event is triggered when the collapsible page element is displayed (and the CSS transition effect has been executed).
hide: This event is triggered immediately after the hide instance method is called.
hidden: This event is triggered when the collapsible page element is hidden from the user (and the CSS transition effect has been completed).

The above is the entire content of this article, I hope it will be helpful to everyone’s study.

Python vs. JavaScript: Performance and Efficiency ConsiderationsApr 30, 2025 am 12:08 AM

The differences in performance and efficiency between Python and JavaScript are mainly reflected in: 1) As an interpreted language, Python runs slowly but has high development efficiency and is suitable for rapid prototype development; 2) JavaScript is limited to single thread in the browser, but multi-threading and asynchronous I/O can be used to improve performance in Node.js, and both have advantages in actual projects.

The Origins of JavaScript: Exploring Its Implementation LanguageApr 29, 2025 am 12:51 AM

JavaScript originated in 1995 and was created by Brandon Ike, and realized the language into C. 1.C language provides high performance and system-level programming capabilities for JavaScript. 2. JavaScript's memory management and performance optimization rely on C language. 3. The cross-platform feature of C language helps JavaScript run efficiently on different operating systems.

Behind the Scenes: What Language Powers JavaScript?Apr 28, 2025 am 12:01 AM

JavaScript runs in browsers and Node.js environments and relies on the JavaScript engine to parse and execute code. 1) Generate abstract syntax tree (AST) in the parsing stage; 2) convert AST into bytecode or machine code in the compilation stage; 3) execute the compiled code in the execution stage.

The Future of Python and JavaScript: Trends and PredictionsApr 27, 2025 am 12:21 AM

JavaScript will promote the development of web technology, 3. Cross-platform development will become a hot topic, and 4. Performance optimization will be the focus. Both will continue to expand application scenarios in their respective fields and make more breakthroughs in performance.

Python vs. JavaScript: Development Environments and ToolsApr 26, 2025 am 12:09 AM

Both Python and JavaScript's choices in development environments are important. 1) Python's development environment includes PyCharm, JupyterNotebook and Anaconda, which are suitable for data science and rapid prototyping. 2) The development environment of JavaScript includes Node.js, VSCode and Webpack, which are suitable for front-end and back-end development. Choosing the right tools according to project needs can improve development efficiency and project success rate.

Is JavaScript Written in C? Examining the EvidenceApr 25, 2025 am 12:15 AM

Yes, the engine core of JavaScript is written in C. 1) The C language provides efficient performance and underlying control, which is suitable for the development of JavaScript engine. 2) Taking the V8 engine as an example, its core is written in C, combining the efficiency and object-oriented characteristics of C. 3) The working principle of the JavaScript engine includes parsing, compiling and execution, and the C language plays a key role in these processes.

JavaScript's Role: Making the Web Interactive and DynamicApr 24, 2025 am 12:12 AM

JavaScript is at the heart of modern websites because it enhances the interactivity and dynamicity of web pages. 1) It allows to change content without refreshing the page, 2) manipulate web pages through DOMAPI, 3) support complex interactive effects such as animation and drag-and-drop, 4) optimize performance and best practices to improve user experience.
