Hiding a Button in Javascript

visibility="hidden"

is very useful, but it will still take up space on the page. You can also use

display="none"

because that will not only hide the object, but make it so that it doesn't take up space until it is displayed. (Also keep in mind that display's opposite is "block," not "visible")

Something like this should remove it

document.getElementById('x').style.visibility='hidden';

If you are going to do alot of this dom manipulation might be worth looking at jquery

document.getElementById('btnID').style.visibility='hidden';

//Your code to make the box goes here... call it box
box.id="foo";
//Your code to remove the box goes here
document.getElementById("foo").style.display="none";

of course if you are doing a lot of stuff like this, use jQuery

If the space on that page is not disabled then put your button inside a div.

<div id="a1">
<button>Click here</button>
</div>

Using Jquery:

<script language="javascript">
$("#a1").hide();
</script>

Using JS:

<script language="javascript">
document.getElementById("a1").style.visibility = "hidden";
document.getElementById("a1").style.display = "none";
</script>

when you press the button so it should call function that will alert message. so after alert put style visible property . you can achieve it using

function OpenAlert(){
        alert("Getting the message");
        document.getElementById("getMessage").style.visibility="hidden";
        
    }

 <input type="button" id="getMessage" name="GetMessage" value="GetMessage" onclick="OpenAlert()"/>

Hope this will help . Happy to help

If you are not using jQuery I would suggest using it. If you do, you would want to do something like:

$( 'button' ).on(
   'click'
   function (  )
   {
       $( this ).hide(  );
   }
);

<script>
    $('#btn_hide').click( function () {
      $('#btn_hide').hide();
    });
</script>
<input type="button" id="btn_hide"/>

this will be enough

You can use this code:

btnID.hidden = true;

var start = new Date().getTime();
while ((new Date().getTime() - start) < 1000){
  } //for 1 sec delay
