Collapsible DIV

This page demonstrates how to create a collapsible div, compatible with most browsers. If the browser has scripting disabled, the page content will simply load with all div's expanded.

<script type="text/javascript">
 
var sections = new Array("generalDocuments","sketchPlan","designOptions","completeSet");		
 
function init(){
	// if we have javascript, set up the page accordingly
	var i;
	for(i=0; i<sections.length; i++){
		toggleRoll(sections[i]);
	}
}
 
function getElem(elemID){
	if(document.all){
		return document.all(elemID);
	}else if(document.getElementById){
		return document.getElementById(elemID);
	}else if(document.layers){
		return document.layers[elemID];
	}
}
 
function toggleRoll(elemID){
	var elem = getElem(elemID);
 
	if(elem.style.display != "none"){
		elem.style.display = "none";
		var img = getElem(elemID + "Img");
		img.src = "_img/rflippy.gif";
	}else{
		elem.style.display = "block";
		var img = getElem(elemID + "Img");
		img.src = "_img/dflippy.gif";
	}
 
	// clear the user selection, in case they have mistakenly double clicked
	if(typeof window.getSelection != "undefined"){  // Mozilla
		var sel = window.getSelection();
		if(sel && typeof sel.removeAllRanges != "undefined")
			sel.removeAllRanges();
	}else if(typeof document.selection.empty != "undefined"){  // IE
		document.selection.empty();
	}
} 
 
</script>
