onclick calling hide-div function not working

I've been fighting with this simple piece of code forever. I'm trying to use a <button> to call a simple JavaScript function to hide a <div>.

HTML:

<button type="button" onclick="close('wrong')">OK</button>

JavaScript:

function close(ID)
{
    document.getElementById(ID).style.display="none";
}

I'm sure it's something really simple, I just can't, for the life of me, find it.

Answer

Try changing the close function name to something else like closeit because it may be confusing it with the window.close() function.

Answer

Try document.getElementById('wrong').setAttribute('style', 'display:none');

Answer

Let's do something in jQuery:

<button type="button" id="btn">OK</button>
<div id="myDiv">Div's contents here</div>

Now, you need just use the code below to do what you want:

<script type="javascript">
$(document).ready(function(e) {    
   $("#btn").click(function () {
      $("#myDiv").hide();
   });
});
</script>

Notice: you can have some properties for hide() function: Fast and slow. This will affect on the speed of hiding action.

$("#myDiv").hide("slow");

I hope this can help you.
