Nonsense not much to say, directly on the code!
<! DOCTYPE html>
<meta charset= "Utf-8" >
<title></title>
<body>
<p id= "Demo" > Click button. </p>
<button onclick= "getnowformatdate ()" > I dot Dot </button>
<div id= "Da" ></div>
<script>
function Getnowformatdate () {
var date = new Date ();
var seperator1 = "-";
var Seperator2 = ":";
var month = Date.getmonth () + 1;
var strdate = Date.getdate ();
if (month >= 1 && month <= 9) {
month = "0" + month;
}
if (strdate >= 0 && strdate <= 9) {
Strdate = "0" + strdate;
}
var currentdate = date.getfullyear () + seperator1 + month + seperator1 + strdate + "" + date.gethours () + Seperator2 + da Te.getminutes () + Seperator2 + date.getseconds ();
var t = document.getElementById ("Da");
t.innerhtml = currentdate
Console.log (currentdate);
}
</script>
</body>
JS gets the current datetime format as "Yyyy-mm-dd HH:MM:SS"
