Does anyone know how to adapt the following script so that it works with 2 checkboxes and 2 layers, all hidden until a checkbox is selected.   If the other checkbox is selected the layer should hide,with the other becoming visible.


<html>

<body>
 

<input id="inp1" onclick="ToggleVisibility();" type="checkbox" checked="true" >Show DIV</input>

<br/>
 

<div id="div1" style="background-color:#aaaaaa;font-size:20pt;">

Hello World!

</div>
 

<script>
 

function ToggleVisibility()

    {

    var objInp = document.getElementById("inp1");

    var objDiv = document.getElementById("div1");
 

    if (objInp.checked) objDiv.style.visibility = ""; else objDiv.style.visibility = "hidden";

    }
 

</script>
 
 

</body>

</html>

If you can only have 1 visible at a time, might be better to use a radio group
