CSS Visibility

See attached.

I want the button "Next" to become visible when "Show" is pressed.

Doesn't work.

Why?

Basically a spelling error

getDocumentByID
Instead of
getDocumentById
<!DOCTYPE html>

<html>
<head>
<title>Test Visibility</title>
<script type="text/javascript">
	function make_visible() {
		document.getElementById("bsnnext").style="visibility:visible;";
	}	
</script>
</head>
<body>
<input type="button" value="Show" onMousedown="make_visible();"><br>
Hidden button follows<br><br>
<input type="button" id="bsnnext" style="visibility:hidden;" value="Next">
</body>
</html>

To Julian Hansen,

Changed as you indicated.

But isn't it getElementByID, NOT getDocumentByID?

Still fails.

Note also this which has it the way I originally had it:

My gut feel is it has to do with the .style="visibility:visible;" part

Oops - how ironic is that - pointing out a spelling error with another one.

You are correct it is getElementId  - late and too many posts.

The code still has the spelling error (letters are correct - case is not) - my intent with my last post was not the Document bit - that was a typo it was the ID bit - the second 'd' should be lower case - as per the full post I did.

So, should be

getElementById
Not
getElementByID
<!DOCTYPE html>

<html>
<head>
<title>Test Visibility</title>
<script type="text/javascript">
  function make_visible() {
    // CHANGE getElementByID TO getElementById
    document.getElementById("bsnnext").style="visibility:visible;";
  }  
</script>
</head>
<body>
<input type="button" value="Show" onMousedown="make_visible();"><br>
Hidden button follows<br><br>
<input type="button" id="bsnnext" style="visibility:hidden;" value="Next">
</body>
</html>
