What does element.attr('foo', 'bar') do? and what does element.attr('foo', 'bar').toggle(functiona, functionb) do?

What does element.attr('foo', 'bar') do? and what does element.attr('foo', 'bar').toggle(functiona, functionb) do?

What I'm really trying to do is modify the attached code snippet so that, in the case that an object has no child objects, the "Subcategory" link does not appear.

taxDiv.each(function(index,element) {
		id = $(element).attr('id');
		t = id.split('-',2);
		itemCode = t[1];
		ele = $('<a><b>Subcategories&raquo;</b></a>').attr('id', 'more-'+itemCode).toggle(RRDB.sic.getChildren,RRDB.sic.removeChildren)
		$(element).append(ele);
	});

The attribute is all the extra values contained within the element tag. For example <a href="link.html" id="link1" class="myClass">Click Here</a>, href, id, and class are attributes of the anchor (i.e. a) tag.

You are probably looking for something like innerHTML:

ysfx, does the attr call in question set one attribute with its related value?

attr('foo', 'bar') sets one attribute with its related value.
toggle(functiona, functionb) assigns those functions to the object to be called on event.

The updated code is attached, although it's not 100% yet.
taxDiv.each(function(index,element) {
		id = $(element).attr('id');
		t = id.split('-',2);
		itemCode = t[1];
		thisID = 'more-'+itemCode;
		thisBaseCode  = thisID.substr(thisID.indexOf('-')+1);
		ele = $('<a><b>Subcategories&raquo;</b></a>').attr('id', 'more-'+itemCode).toggle(RRDB.sic.getChildren,RRDB.sic.removeChildren)
		if(RRDB.sic.hasChildren(thisBaseCode)){
			$(element).append(ele);
		}
