Answer 1

//某一节点下的所有子节点
function getChildren(id/*节点ID*/){
var $tree = $('#tree');
var node = $tree.tree('find',id);
var childrenNodes = $tree.tree('getChildren',node.target);
return childrenNodes;
}
//某节点的一级节点
function getSubChildren(id){
var $tree = $('#tree');
var node = $tree.tree('find',id);
var subNodes = [];
$(node.target)
.next().children().children("div.tree-node").each(function(){
subNodes.push($tree.tree('getNode',this));
});
return subNodes;
}
