I'm using TreeVirtual and I created buttons to expand and collapse all nodes
within the tree. Under IE8, the expand runs slow enough that I get the "Stop
running this script?" message box. Any suggestions on how to speed it up?
Collapse is quick. The slow part appears to be the nodeSetOpened call.
Here's my code-
var treeData = tree.getDataModel().getData();
for (var i = treeData.length - 1; i > 0; i--) {
if (treeData[i]) {
tree.nodeSetOpened(treeData[i], true);
}
}
If I had to guess, it's the screen updates between each call that is slowing it
down. Is there a way to disable it while updating all the nodes?
Thanks,
Rich
