When a node is checked, the 'onBeforeCheck' event only be triggered on this node. You can call 'getChildren' method to get its child nodes including their state in this event.

Code:

$('#tt').tree({
	onBeforeCheck:function(node){
		var nodes = $(this).tree('getChildren', node.target);
		console.log(nodes)
	}
})

thanks stworthy for your answer, but
i've already try that, if the node doesn't have child it will trown an error like this on firebug:

Code:

TypeError: _d7 is undefined

so how to check some node hava a child node or not?
thanks

Please call 'isLeaf' method to determine the specified node is leaf.

Code:

var b = $('#tt').tree('isLeaf', node.target);
if (b){
  console.log('is leaf');
}
