We can use jQuery's 'append' or 'prepend' method to add content to the section of a website. This can be done by selecting the element using jQuery's 'selector' method and then using the appropriate method to add the desired content. Additionally, we can also use JavaScript's 'innerHTML' property to add content to the section. There are quite some ways of adding content to head tag programmatically. Today we are going to discuss 3 of them − Using jQuery's .append() method − Using JavaScript's document.createElement() method − Using JavaScript's insertAdjacentHTML() method − Using these 3 ways ...

We can use the CSS "::before" pseudo-element to dynamically add a comma before each list item, except for the first one. By targeting the list item and using the "content" property, we can insert a comma before the list item's content. Additionally, we can use the ":not(:first-child)" pseudo-class to ensure that only the non-first list items have the comma added. Consider we have the following HTML DOM: Item 1 Item 2 Item 3 Item 4 We will discuss two different approaches in this article that ... Read More
We can add code input in React.js by creating a component that renders an input field and handles user input. To do this, we can use the built-in React hooks such as useState to manage the input value and handle changes. Additionally, we can also use event handlers to handle user input and update the input value accordingly. Let us first understand what ReactJS and analyze the use of React Hook “useState” as it will be used inside the code. ReactJS React is a JavaScript library for building user interfaces. It makes it easy to create interactive UIs. Design simple ... Read More
We can use the jQuery .addClass() method to add multiple classes to an element. We simply need to pass a string of class names separated by a space as the argument. To remove multiple classes, we use the .removeClass() method and pass in the same string of class names. Both of these methods can be chained together to add and remove multiple classes at once. But before proceeding with that let us have a look at what jQuery offers and how it makes web programming easier over plain JavaScript. What is jQuery jQuery is a JavaScript library that simplifies ... Read More
We can use the JavaScript method "createElement" to create a new element. Then, we can use the method "appendChild" to add the element to a parent element on the HTML page. To position the element horizontally, we can use CSS styles such as "display:inline-block" or "float:left/right" on the newly created element. Suppose a situation where we want to depict a graphical representation of a Linked List data structure. Every time the user clicks on a button, a new node, represented by a green circle in our case, should get prepended to the list of nodes horizontally. And the text inside ... Read More
We can add an active class to a custom list group item in Bootstrap 4 by using JavaScript or jQuery. This can be achieved by adding an onclick event to each list group item and then using the "addClass" method to add the active class to the item that was clicked. By doing this, we can easily create a custom list group with an active state that changes based on user interaction. Bootstrap Intro Bootstrap is a popular open-source front-end development framework. It helps to create responsive and mobile-first webpages by providing a set of pre-designed CSS and JavaScript ...

To add a tooltip to a div using JavaScript, first create a function that will generate the tooltip content. Next, add an event listener to the div that will call the function and display the tooltip when the div is hovered over. Finally, use CSS to style the tooltip and position it appropriately. A tooltip is a small text box that appears when a user hovers over a specific element on a webpage, such as a button, link, or image. The tooltip typically contains additional information or context about the element that the user is hovering over. Tooltips are commonly ... Read More
To add a line through to a canvas-type text using Fabric.js, you can use the "set('textDecoration', 'line-through')" method on the text object. This method allows you to set the textDecoration property of the text object to "line-through", which will add a line through the text. Finally, you need to call the "renderAll()" method to update the canvas with the new text decoration. Fabric.js is a JavaScript library for working with object-oriented canvas graphics. It provides an easy-to-use API for creating and manipulating canvas elements, such as shapes, text, and images. With Fabric.js, you can create complex canvas graphics and animations ... Read More
We will learn how to implement multiple input checkbox. The checkbox input selector will have the following functionalities − Multiple options can be selected using the checkbox. Chosen options will be displayed as a separate list. Delete icon will be provided against each chosen option to uncheck / delete that option. Another thing to note is that we will not be using any third-party library to achieve these functionalities and everything will be written in HTML + JavaScript + CSS only. Approach We will have an object whose key will be used as the label for checkbox ... Read More
In Backbone.js, views are typically associated with a model and have access to the model's data through the view's this.model property. To access the data of the model in a view, you can use the get() method on the model, passing in the name of the attribute you wish to retrieve. Backbone.js is a lightweight JavaScript library that helps to structure and organize client-side code.Backbone.js provides a model-view-controller (MVC) framework for building web applications. The model represents the data, the view represents the UI, and the controller manages the interactions between the two. This structure allows for a clear separation ... Read More
