I have a form with two fields: shape and color.

where people select a shape an image of the shape appears, and a default color image appears.

When they select a color, it changes the color image. But if they go back and change the shape, I don't want it to turn the color back into the default image. But I don't know how to do this script.

Here's the function I have, but I don't know how to write it:

function changecolor(picName,imgName)

 {
	 var idx = filepath.pic4
   if (idx = "/images/leaf_shapes/entire/transparent1.gif")
    {
      imgOn=eval(imgName + ".src");
      document[picName].src= imgOn;
    }
 }

The rest of the code:

<html>
<head>
<link rel="stylesheet" type="text/css" href="scriptstest25.css" />
<title>Search by leaf shape</title>


<script type="text/javascript">

//jkmegamenu.definemenu("anchorid", "menuid", "mouseover|click")
jkmegamenu.definemenu("megaanchor", "megamenu1", "mouseover")
jkmegamenu.definemenu("megaanchor2", "megamenu2", "mouseover")
jkmegamenu.definemenu("megaanchor3", "megamenu3", "mouseover")
jkmegamenu.definemenu("megaanchor4", "megamenu4", "mouseover")
</script>

Turpentyne,

By constructing the leaf images as "masks", it should be possible to do something like this:

  "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<style type="text/css">
#leafImage {
	width: 70px;
	height: 70px;
	border: 2px solid #666;
}
#controls {
	margin: 5px 0px;
	padding: 5px;
}
</style>

<script type="text/javascript">
onload = function() {
	if(document.images) {
		var leafs = [];//new Array
		leafs[0] = new Image(); leafs[0].src = "/images/leaf_shapes/entire/transparent1.gif";    leafs[0].alt = "Pure";
		leafs[2] = new Image(); leafs[2].src = "/images/leaf_shapes/entire/leaf_auriculate.png"; leafs[2].alt = "Auriculate";
		leafs[3] = new Image(); leafs[3].src = "/images/leaf_shapes/entire/leaf_cordate.png";    leafs[3].alt = "Cordate";
		leafs[4] = new Image(); leafs[4].src = "/images/leaf_shapes/entire/leaf_cuneate.png";    leafs[4].alt = "Cuneate";
		var leafImage = document.getElementById('leafImage');
		var leafCodeMenu = document.formsearch1.leafShape;
		var leafBackgroundMenu = document.formsearch1.leafColor;
		function setLeaf() {
			var leafCode = leafCodeMenu[leafCodeMenu.selectedIndex].value;
			var leafBackground = leafBackgroundMenu[leafBackgroundMenu.selectedIndex].value;
			leafImage.src = leafs[leafCode].src;
			leafImage.alt = leafs[leafCode].alt;
			leafImage.style.backgroundColor = leafBackground;
		};
		leafCodeMenu.onchange = leafBackgroundMenu.onchange = setLeaf;
		setLeaf();
	}
};
</script>
</head>

</select>
</div>
</form>

</body>
</html>

By using select menus, you would lose the hover effect but the advantage is great simplicity.
