Twitter Bootstrap 3 – JavaScript Components

Twitter Bootstrap: A simple and powerful CSS framework and JavaScript components detailed explanation

Twitter Bootstrap is one of the easiest and easy-to-use CSS frameworks on the Internet. Even developers who don’t understand CSS can easily build basic templates. But it is not just for beginners, and its powerful JavaScript component set is also popular with designers, easy to use and fast integration into projects. This tutorial will dive into some of the best Twitter Bootstrap JavaScript components and how to use them.

Key points:

• Twitter Bootstrap 3 is a powerful CSS framework with comprehensive JavaScript components, and can easily build templates even if you don’t understand CSS.
• Bootstrap 3's JavaScript components are written based on jQuery, including Modal, Dropdown, ScrollSpy, Tab, Tooltip, Popover and Alert. Each component has its own specific features and can be customized to suit different project needs.
• Using these JavaScript components requires downloading Bootstrap 3 from getbootstrap.com, as well as a web browser (recommended Google Chrome) and a text editor (such as Sublime Text). To ensure that JavaScript components work properly, Bootstrap CSS must be included.
• Bootstrap 3's JavaScript component is one of the important reasons why it is so popular. They provide convenient solutions for developers who do not understand CSS and designers who want to improve design efficiency.

Get used:

First, you need to download Bootstrap 3 from getbootstrap.com, prepare a web browser (preferably Google Chrome) and a text editor (I'm using Sublime Text). It should be noted that Bootstrap's JavaScript components are written based on jQuery, so jQuery is required to use them. After downloading Bootstrap 3, copy the contents of the dist folder to the new workspace. You may wonder, why do you still need CSS and font folders to learn JavaScript? Many Bootstrap JavaScript components rely on CSS to work properly, so they won't work properly without Bootstrap CSS included. Bootstrap 3 also allows us to use each module separately without downloading all JavaScript components. This tutorial ends with how to use modules alone, instead of including all components. This tutorial will explain the following major Twitter Bootstrap JavaScript components:

1. Modal (modal box)
2. Dropdown (drop-down menu)
3. ScrollSpy (scroll listening)
4. Tab (tab)
5. Tooltip (Tooltip)
6. Popover (popup)
7. Alert (warning box)

We will explain each component one by one and do some experiments to get a custom Bootstrap 3 JavaScript component. Click here to view the demo page.

Modal (modal box)

Modal boxes are similar to traditional warning boxes, but are more powerful, including modal titles, modal bodies, modal footer, close buttons, and close symbols in the upper right corner. It can be used in many applications for confirmation windows, such as before making payments or deleting an account, etc.

<button type="button" class="btn btn-primary btn-lg" data-toggle="modal" data-target="#myModal">
  启动演示模态框
</button>

<div class="modal fade" id="myModal" tabindex="-1" role="dialog" aria-labelledby="myModalLabel" aria-hidden="true">
  <div class="modal-dialog">
    <div class="modal-content">
      <div class="modal-header">
        <button type="button" class="close" data-dismiss="modal" aria-hidden="true">×</button>
        <h4 class="modal-title" id="myModalLabel">模态标题</h4>
      </div>
      <div class="modal-body">
        <h1>Hello World!</h1>
      </div>
      <div class="modal-footer">
        <button type="button" class="btn btn-default" data-dismiss="modal">关闭</button>
        <button type="button" class="btn btn-primary">保存更改</button>
      </div>
    </div>
  </div>
</div>

Bootstrap Modal contains three parts: title, body, and footer. You can decide what to place in each section.
