How To Create A New Tab In Javascript

Introduction to Tabs in Web Development

Tabs are a common feature in web development, allowing users to easily switch between multiple sections of content on a single page. With tabs, users can quickly navigate between related information without having to load separate pages or scroll through long lists.

In web development, tabs are usually created using a combination of HTML, CSS, and JavaScript. HTML is used to create the basic structure of the tabs, CSS is used to style their appearance, and JavaScript is used to handle user interactions and switch between tabs.

There are several ways to create tabs in web development, including using a pre-built library or creating custom tabs from scratch. Depending on the complexity of your design and the functionality you require, you may choose one method over another.

Overall, tabs are a useful and versatile feature in web development, providing users with an intuitive way to navigate between related content. By learning how to create tabs in JavaScript, you can enhance the usability and user experience of your web applications.

Basic setup for creating tabs using HTML and CSS

To create tabs using HTML and CSS, you can follow these basic steps:

1. Create the HTML structure for tabs:

Tab 1 content

Lorem ipsum dolor sit amet, consectetur adipiscing elit.

Tab 2 content

Sed do eiusmod tempor incididunt ut labore et dolore magna aliqua.

Tab 3 content

Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea commodo consequat.


2. Add CSS styles to hide all tab content except the first one:
.tabcontent {
display: none;

.tabcontent:first-child {
display: block;

3. Add JavaScript to handle tab clicks and show the corresponding tab content:
function openTab(evt, tabName) {
var i, tabcontent, tablinks;
tabcontent = document.getElementsByClassName(“tabcontent”);
for (i = 0; i < tabcontent.length; i++) {
tabcontent[i].style.display = “none”;
tablinks = document.getElementsByClassName(“tablinks”);
for (i = 0; i < tablinks.length; i++) {
tablinks[i].className = tablinks[i].className.replace(” active”, “”);
document.getElementById(tabName).style.display = “block”;
evt.currentTarget.className += ” active”;

With these basic steps, you can create tabs using HTML and CSS. Customize the styles and tab content as per your requirements.

Understanding the behavior of tabs in javascript

When it comes to creating tabs using JavaScript, it’s important to understand how the behavior of tabs works. Tabs are essentially a way to switch between different sections or pages of content without having to navigate away from the current page. In JavaScript, tabs can be created using a number of different techniques, including using the HTML <ul> and <li> elements, creating dynamic tabs using JavaScript, or using a third-party library like jQuery UI.

Regardless of the method used to create tabs, it’s important to understand that the behavior of tabs is essentially the same. When a user clicks on a tab, the corresponding content is displayed, while the other content is hidden. This can be achieved in a number of ways, including using CSS to hide and show content based on the active tab, or using JavaScript to add and remove classes to toggle the visibility of content.

Another important aspect of tab behavior is the ability to switch between tabs using keyboard shortcuts. This is an important accessibility feature that allows users to navigate through tabs using only their keyboard, rather than relying on a mouse or other input device. By adding support for keyboard shortcuts, you can ensure that your tabs are accessible to a wider audience.

In conclusion, understanding the behavior of tabs in JavaScript is crucial to creating effective and functional tabs on your website. By taking the time to learn about how tabs work, you can ensure that your tabs are easy to use, accessible, and provide a great user experience.

Creating a new tab using Vanilla JavaScript

When it comes to building web applications, it’s often necessary to create a new tab programmatically in JavaScript. While there are many libraries and frameworks available that can simplify this task, it’s also possible to accomplish it using plain JavaScript, also known as Vanilla JavaScript.

To create a new tab using Vanilla JavaScript, you can use the `` method. This method creates a new browser window or tab, depending on the user’s settings, and returns a reference to it. Here’s an example:

const url = “”;
const tab =, “_blank”);

In this example, we first define the URL for the new tab, then call `` with two arguments: the URL, and a string specifying that the tab should be opened in a new window or tab (in this case, `_blank`).

Once the `` method is called, the browser will create a new tab and load the specified URL. The `tab` variable in our example will hold a reference to the newly created tab, which can be used later to interact with the tab programmatically.

Overall, creating a new tab using Vanilla JavaScript is a simple task that can be accomplished with just a few lines of code. By using this approach instead of a library or framework, you can keep your code more lightweight and avoid unnecessary dependencies.

Enhancing the functionality of tabs with jQuery and Bootstrap

If you’re looking to make your website’s tabs more dynamic, using jQuery and Bootstrap can be a great solution. With these powerful tools, you can add new functionality to your tabs that allows you to create new tabs, as well as rearrange and delete existing ones.

One of the key benefits of using jQuery and Bootstrap for tab functionality is their ease of use. With just a few lines of code, you can quickly and easily create professional-looking tabs that are responsive and mobile-friendly. Plus, these tools offer a range of customization options, so you can easily tailor the look and feel of your tabs to match your website’s design.

Some of the features you can add to your tabs with jQuery and Bootstrap include:

  • Dynamic creation of new tabs
  • Tab scrolling and pagination
  • Drag and drop reordering of tabs
  • Customizable tab styling and animations

Styling and Customizing Tabs with CSS

Once you have created new tabs in your web page using JavaScript, you can use CSS to style and customize them to match the overall design of your site. Here are some CSS properties you can use to customize your tabs:

  • background-color – sets the background color of the tab.
  • color – sets the font color of the tab.
  • border – sets the border of the tab.
  • padding – sets the padding inside the tab.
  • font-size – sets the font size within the tab.

Here’s an example of CSS code that could be used to style tabs:

.tab {
background-color: #f2f2f2;
color: black;
border: 1px solid grey;
padding: 10px;
font-size: 16px;
} {
background-color: white;
border-bottom: none;
font-weight: bold;

This code will set the background color, font color, border, padding, and font size for all tabs on the page with a class of .tab. The selector then specifies additional styles for the active tab, including a white background color, bold font weight, and no bottom border.

By using CSS to customize your tabs, you can create a visually appealing and user-friendly interface for your website or web application.

Troubleshooting common issues and errors when creating tabs in javascript

Creating tabs in JavaScript is an essential aspect of front-end web development. Tabs provide efficient ways to organize pages and content on a website. However, creating tabs in JavaScript can be challenging, and developers may encounter some common issues and errors. The following are some of the troubleshooting tips to help you fix them.

1. Incorrect selectors

The most common issue developers experience when creating tabs in JavaScript is incorrect selectors. Ensure that your selectors target the correct HTML elements. Incorrect selectors can cause errors such as unexpected behavior, missing tabs, or non-functional tabs.

2. Missing or misplaced closing tags

Ensure that your code has proper tag nesting, for example, check that every <div> has its closing tag before starting another tag. Omitting or incorrectly placing a closing tag can lead to JavaScript running improperly and causing problems with your tabs.

3. Incorrect syntax

Ensure that your code uses the correct syntax, especially when declaring variables. Incorrect syntax can lead to errors and break the execution flow.

4. Conflicts with other scripts

Occasionally, tabs created with JavaScript may conflict with other scripts on your website. If this occurs, try removing other scripts until your tabs work as intended.

By following these tips, you can help minimize common issues and errors you may encounter while creating tabs in JavaScript. Successful tab implementation can provide an excellent user experience and make your website more organized and visually appealing.
