The value of the name attribute of the cftree tag for which you want the object. |
Returns
An object of type YAHOO.widget.TreeView.
Usage
Use this function to manually update the tree. If you populate the tree by using a bind expression, the refresh call causes the bind expression to be re-evaluated and repopulates the tree root nodes. Use this function any time you must get the latest data from the server independent of an event that triggers the cftree bind expression, for example, use this function to periodically refresh a file/folder tree to represent the status of the server.
