extjs - how many children do you have a node I selected? -
i've been looking have not located anything, , can know how many children have node selected?
greetings , thank you....
i suppose working treestore right?
if so, according doc on nodeinterface can use attribute childnodes , use array.
so childnodes.length
.
just note, careful if use lazy loading, childnodes might empty if it's not loaded already.
