It is possible to return to the previous selected node?
what is the “preserve” parameter for the selectItem(itemId, mode, preserve) function?
What do you mean under “return”?
According to the documentation:
docs.dhtmlx.com/doku.php?id=dhtm … lectitem&s[]=selectItem
preserve - (boolean) if true, the earlier selected nodes will be preserved = saves previous nodes
How to select the previous selected node?
For example I created dynamically a new node, but if something happens, I will remove the new node and select the previous one.
There is an “onSelect” event:
docs.dhtmlx.com/doku.php?id=dhtm … onselect&s[]=onselect
Inthis case you can push your selected item to a special array to take it from there at any time you need.
OK, thanks. That is the easy solution. I thought that there was a way to use the preserve parameter of selectItem function to do so
In your case parameter ‘preserve’ is not suitable, because when you delete some items, tree unselects all.
