Title: Get all tree nodes
Post by: ClSoft on March 06, 2013, 08:22:46 AM

Hi all
after DragDrop, I need to read all Tree nodes because I need to write them into database (so I can display it again).
Here is my try:

function onDropVrsta(targetNode,source,point)
{
var roots = $('#boq_vrste').tree('getRoots'); // because it can be more roots
for(var i = 0; i < roots.length; i++){
alert(roots.id); // here I have root id for each root node
}

I need to somehow read all other nodes (for each root) and if possible, read ID and ParentID
How to do that?
Thanks.

I know all children ID's but that's all:

var children = $('#boq_vrste').tree('getChildren');
for(var c = 0; c < children.length; c++){
alert(children[c].id);
}

but how to find parent id from current node?
Thanks a lot!

Please call 'getParent' method to get a node's parent node.

Hi
I try that already, but don't know how to use it.
This is what I try:

var children = $('#boq_vrste').tree('getChildren');
for(var c = 0; c < children.length; c++){
var nodeID = children[c].id;
var pnode = $('#boq_vrste').tree('getParent',nodeID.target);
alert(pnode.text);

and
var pnode = $('#boq_vrste').tree('getParent',nodeID);
alert(pnode);

etc..
thanks.

Try the following code:

Code:

var t = $('#boq_vrste');
var children = t.tree('getChildren');
for(var i=0; i<children.length; i++){
	var node = children[i];
	var pnode = t.tree('getParent', node.target);
	if (pnode){
		console.log(node.text + '->' + pnode.text);
	}
}
