Expand/Colapse iconCls for Tree

[iceh]

Hi,

how do I add an iconCls dependent on the expand/collapse state to a Tree Item?

I just found the iconCls in the documentation.

Any idea on this one?

When collapse or expand a node,  you can call 'update' method to update the iconCls for this node.

Code:

<ul class="easyui-tree" data-options="
		data:data,animate:true,
		onBeforeExpand:function(node){
			$(this).tree('update',{
				target:node.target,
				iconCls:'icon-e'
			});
		},
		onBeforeCollapse:function(node){
			$(this).tree('update',{
				target:node.target,
				iconCls:'icon-c'
			});
		}"></ul>

OK cool looks simple.

I use the node's attributes for the storage of the icons.
