After doing some research on various development platforms, I stumbled upon this JSFiddle that seems to have a solution for my requirements. The only thing missing is the ability to input a specific word (without user input) and automate the process at fixed intervals.
Appreciate any help with this. Thanks.
Is this what you're looking for?
window.setInterval(function() {
var screenWidth = window.innerWidth;
var screenHeight = window.innerHeight;
var displayText = "predefined message";
var element = document.createElement("span");
element.textContent = displayText;
element.style.position = "absolute";
element.style.left = Math.round(Math.random() * screenWidth) + "px";
element.style.top = Math.round(Math.random() * screenHeight) + "px";
document.body.appendChild(element);
}, 1000);
See an example on jsfiddle.
