eachOpen

iterates through opened nodes of the tree (both parent and child)

code	function	a function that needs calling for each data item
master	object	an object that the function is applied to (this by default)
pid	string	the parent node id. Used to iterate through a specific branch

Example

//iterates through all items of the tree
tree.data.eachOpen(function(obj){
   console.log(obj.value)
});
 
//iterates through items with $parent="2"
tree.data.eachOpen(function(obj){
   console.log(obj.value)
}, this, "2");

Be aware of the following issues:

• eachOpen iterates through both parent and child nodes.
• The eachOpen's function takes the data item object as a parameter.
• If you specify the 3rd parameter (pid), eachOpen will iterate only through child nodes of the branch (without iterating through the specified parent node).
