[code] dhtmlxEvent (document.getElementById(‘insertNewChild’), “click”, function(ev){
var auto_increment = dhtmlxAjax.postSync(“process.php”, ‘action=auto_increment&table=mytree’);
tree.insertNewChild(tree.getSelectedItemId(),auto_increment.valueOf(),"A NEW CHILDS NAME",0,0,0,0,"CHILD,SELECTED");
backup();
})
[/code]
This Event listener dosn’t work. Why?
If I replace auto_increment.valueOf() with the int Number ‘90’ it also stops.
What I want to do is just to use the AJAX result as the id of the new nodes and the increment the value of auto_increment to auto_increment+1.
It is the most important issue that I have to resolve.
