Access Element from Table Using JavaScript
To access a element from a table using JavaScript, you can first use the document.getElementById() or document.getElementsByTagName() method to access the table element. Then, you can use the table's childNodes property to access the elements within the table. Our focus will be on changing the background color of the current row (the row on which we currently are) when we hover over it and reverting the background color to normal when the mouse goes away.Example Therefore, let’s suppose we have the following HTML code to render a table. ...

To accept all pending connection requests on LinkedIn using JavaScript, you would need to use the LinkedIn API and an automation tool. The script would need to navigate to the connection request page and loop through each request, clicking the accept button for each one. This is a very common issue for people who are moderately to highly active on Linkedin. They get many connection requests every day and must manually click on accept against each request to actually accept them. You can, however make use of JavaScript and the window console to automate this whole process and we will ... Read More
The focus of this article will be on what AJAX is, how it works in a nutshell, what makes it such a convenient yet powerful tool and how it is different from JavaScript libraries and JavaScript RunTime Environment. AJAX Introduction and History Ajax, short for Asynchronous JavaScript and XML, is a technique for creating dynamic and interactive web applications. It was first introduced in the early 2000s and has since become a staple of modern web development. The key feature of Ajax is its ability to update parts of a web page without requiring a full page reload. This is ... Read More
In this article we will be discussing how inheritance works in JavaScript and how you can make use of this OOPS characteristic inside the constructor function in JavaScript. We will also be touching a little upon the prototype object in JavaScript. Therefore, some prior knowledge on the same is highly appreciated. In JavaScript, inheritance is a mechanism by which an object can inherit properties and methods from another object. This can be achieved using constructor functions and the prototype property. When creating a constructor function, you can use the prototype property to add properties and methods to the constructor ... Read More
React Native's Fabric architecture is a performance-focused update to the traditional React architecture. It uses asynchronous rendering and a new reconciliation algorithm to improve app performance and reduce the time it takes to update the UI. Fabric also allows for more efficient use of memory and better handling of complex animations and interactions. The Problem In the current architecture, all the UI operations are handled by a sequence of cross-bridge steps. There are four core sections in the current architecture − The React code written by the developer (which is very similar to its web counterpart), The JavaScript that ... Read More
Blob stands for Binary Large Object and they are used to store binary data like images, audio or other multimedia objects, and sometimes binary executable code is also stored as a blob. We can use JavaScript to upload blob like any other data file. JavaScript can upload a Blob using the XMLHttpRequest or fetch API. 1. Using XMLHTTPRequest XMLHttpRequest (XHR) is an API in the form of an object whose methods transfer data between a web browser and a web server. The JavaScript environment of the browser provides the object. It is usually used to send and receive data ... Read More
HTML frames gives a convenient way to divide a browser window into multiple sections. Where each section can load a separate HTML document. We can use JavaScript to load the content into a particular frame using the frames property of the window object. The frames property is an array-like object containing all the frames (including iframes) on the current page. There are many ways in which we can use window.frames[] property to load the content of a document into the frame. Let’s look them one by one − 1. Using Index To target a specific frame, you can use the ... Read More
Globally, Development in Cloud Computing always goes towards almost all IT investments. On the other hand, many businesses have started storing and analyzing the ever-increasing amounts of data in Hadoop. What is Cloud Computing? Cloud Computing always simplify for referring to the internet. Rather than keeping them on the local hard disc, Cloud Computing is the best for moving your applications, computer data, and files to an external server in the cloud. Main Advantages of cloud Computing are Elasticity − Cloud computing provides elasticity by allowing organizations to consume only the necessary resources. To accommodate rising or falling computer ... Read More
Growing Bluetooth technology has given us many advantages and solves the connectivity problem in smaller regions. Bluetooth is known to be the most secure connection between two devices because of its strong Bluetooth signals, other than normal electromagnetic signals. Now Bluetooth is changing the face of many companies' IoT Asset Tracking technology. Previously, many methods were used for asset tracking like QR codes, Barcodes, RFID tags, NFC, etc., and now the companies are looking towards the growing Bluetooth low energy transforming IoT asset tracking. What is IoT Asset Tracking? Asset tracking helps any company track its logistics running all around ... Read More
Electric Vehicles (EVs) are the near future of our generation, and increasing gasoline and diesel prices will eventually bring people toward buying electric scooters or electric cars. And therefore, in the electrical grid of charging vehicles, IoT is essential to provide smart charging. Unlike normal gas stations, electric cars require a much longer time to charge their batteries fully, and an electric station can handle a limited number of cars at a time. Hence, IoT boosts smart charging, and Electric Vehicle Charging keeps the EVs running on the road. Let us discuss the different roles of IoT in Electric Vehicle ... Read More
