Steps to show a message on screen for a duration of 3 seconds using JavaScript

setTimeout(function(){
     document.getElementById("alarmmsg").innerHTML=msg;
     },3000);

The code above is successfully displaying the message but it's not going off the screen as expected. What might be causing this issue?

Answer №1

Show the message initially and then remove it after a 3-second delay.

document.getElementById("alarmmsg").innerHTML = msg;

setTimeout(function(){
    document.getElementById("alarmmsg").innerHTML = '';
}, 3000);

Answer №2

Instead of physically removing it from the element, you are instructing the browser to wait for 3 seconds and then update the innerHTML of alarmmsg with your variable content.

setTimeout(function () {
    document.getElementById("alarmmsg").innerHTML = msg;
}, 3000);

// After 3 seconds, clear alarmmsg's content.
document.getElementById("alarmmsg").innerHTML = "";
