Syntax Users can follow the syntax below to get the relative mouse position while scrolling on the div. $('#main').scroll(function (event) { if (finalScroll != $('#main').scrollTop()) { location_y -= finalScroll; finalScroll = ...

We can use the push() method of the array to enqueue the function in the queue and the shift() method to deque the function from the queue. Below, we will see examples of storing JavaScript functions in the queue and executing them in the queue order. Syntax Users can follow the syntax below to store JavaScript functions in a queue and execute in that order. while (queue.length ... Read More
Storing data in the DOM means storing data in plain text format. For example, we store data in the state variable while using React or any other reactive framework. When the user updates the data in the input field, it stores updated data in the state variable. So, we store data in the state variable before we submit the form. At the time of submitting the form, we use the values of the state variables. In vanilla JavaScript, we can do the same, like storing data in plain text format, and whenever we require to submit the form, we can ... Read More
