Autoclose alert

Question

Is there any way to close a javascript alert() automatically?

I have an alert

alert(\"Error found\");

I want to close

I updated the style settings, so it shows like a splash screen in the center of your page, and centers the text inside it.

Call it like this:

alertTimeout("System Message
This is a test message
This alert will auto-close",5000)

The function:

function alertTimeout(mymsg,mymsecs)
{
 var myelement = document.createElement("div");
myelement.setAttribute("style","background-color: grey;color:black; width: 450px;height: 200px;position: absolute;top:0;bottom:0;left:0;right:0;margin:auto;border: 4px solid black;font-family:arial;font-size:25px;font-weight:bold;display: flex; align-items: center; justify-content: center; text-align: center;");
 myelement.innerHTML = mymsg;
 setTimeout(function(){
  myelement.parentNode.removeChild(myelement);
 },mymsecs);
 document.body.appendChild(myelement);
}
