Assigning a function result to a variable

[rollOrDie]

I have a result that is returned from housingDivAssign () that Im trying to assign to a variable inside the function setEvent ().

 

However I just get the error "is not a function". Is this because Im using it inside another function?

 

function housingDivAssign ()
{
	var housingDiv = document.getElementsByTagName ('div');

	j = 0
	for (i = 0; i < housingDiv.length; i ++)
		{
			if (housingDiv[i].className == 'housingHide')
				{
					var housingSection = new Array ();
					housingSection[j] = housingDiv[i];
					alert (j + ' = ' + housingDiv[i].id);
					j ++;
				}
		}

	return housingSection;
}


function housingTitleAssign ()
{
	var housingTitle = document.getElementsByTagName ('span');

	j = 0
	for (i = 0; i < housingTitle.length; i ++)
		{
			if ((housingTitle[i].className == 'title') || (housingTitle[i].className == 'titleTop'))
				{
					var housingSectionTitle = new Array ();
					housingSectionTitle[j] = housingTitle[i];
					// alert (j + ' = ' + housingTitle[i].id);
					j ++;
				}
		}

	return housingSectionTitle;
}

function setEvent ()
		{
			/* for (i = 0; i < housingSectionTitle.length; i ++)
				{
					alert (housingSectionTitle[i].id);
				} */
			var housing = housingDivAssign ();
			alert (housing[2].id);
		}

setEvent ();

No you can call function inside another function... the reason is because you are calling setEvent() before  your HTML page is rendered.

 

Solutions: Either call setEvent ();  inside onLoad  or call it on some event like onclick..  it will work

I dont understand your return result array. You run a loop, but define new Arrray() in every iteration...does it return more than one result?
