RECURSE DYNAMIC TREE

[malutanpetronel-2]

results is containig a list of node id's
node is tree.getRoot() on the first call

        function expandRecursive(node,results){
                var node;
                var results = results.toString();
                alert(node.children.length + " " + results);
                for (var ki=0, kj=node.children.length; ki<kj; ki++) {
                        var childnode = node.children[ki];
                        var idtoSearch = childnode.data.id;
                        if (parseInt(results.indexOf(idtoSearch)) >= 0){
                                //childnode.expand();
                                expandRecursive(childnode,results);
                        }
                }
        }

all works if i expand manually all the nodes in my dyanmic tree based
on the YUI example

if the nodes are not expanded before, than the procedure fail

how can I fix it or how to do it differently please ? what event and
where to insert it ?

With kind regards

Check property  dataLoader:

http://developer.yahoo.com/yui/docs/YAHOO.widget.Node.html#property_dataLoader

if it is null, go ahead, if it is set, then check dynamicLoadComplete:

http://developer.yahoo.com/yui/docs/YAHOO.widget.Node.html#property_dynamicLoadComplete

If false, don't try to read the element because it is not there yet.

in your for loop:

_tree.subscribe("expandComplete", function (node, arg) {
        if (node == childnode){
                _tree.unsubscribe("expandComplete");
                //code to set new childNode reference
                expandRecursive(childnode,results);
        }
});

fun to watch it work :)

I've tried something like:

if (nodeToExpand.isLeaf){
        onSelect(nodeToExpand);
         nodeToExpand.scrollIntoView();
} else {
         //while (nodeToExpand.expand()){};
        nodeToExpand.expand();
        while (nodeToExpand.dataLoader == 'null'){
         }
}

but Satyam... that freeze the browser, so I assume is not good !
any other hints ?

You're great man ! Is it really fun ! I still need to adjust a little
bit some other things but the trick(in fact is a code) works ) ! Is
reaaly hard with these async requests and responses and :) but Thank
you !

How should I modify the part bellow if recursivity must stop only if
the fathers are also identical:

tree.subscribe( "expandComplete" , function (node, arg) {
        if ((node == childnode)
        tree.unsubscribe( "expandComplete" );
        }
        expandRecursive(childnode, results, IdNod);
}};

With kind regards
