[ka-Map-users] KaLegend tweak III

[Marc Pfister]

I rearranged a few things in the moveLayer functions so that everything
would move in the right direction when the legend is drawn in the right
direction (as detailed yesterday).

I've never worked on any open source programming before - is this the
kosher way to do it? Email code around?

function kaLegend_moveLayerDown(){
	var myLayer= this.oLayer;
	var myDiv = this.myDiv;
	var upperLayer= this.oLayer.domObj.previousSibling;
	var upperDiv = this.myDiv.previousSibling;
	var lowerLayer= this.oLayer.domObj.nextSibling;
	var lowerDiv = this.myDiv.nextSibling;
	
	if(lowerDiv.id!='group___base__'){

		//move layer div in the viewport
		var zUp = upperLayer.style.zIndex;
		var zDown = myLayer.domObj.style.zIndex;
	
myLayer.domObj.parentNode.insertBefore(myLayer.domObj,upperLayer);
		//invert zIndex values
		myLayer.domObj.style.zIndex = zUp;
		upperLayer.style.zIndex = zDown;
		
                // move legend group div
		myDiv.parentNode.insertBefore(lowerDiv,myDiv);
