在ztree中获取选中节点的值

var setting = {
            check: {
                enable: true
            },
            data: {
                simpleData: {
                    enable: true
                }
            },
            callback:{    //第一步
                onClick:zTreeOnClick   
            }
        };

        function zTreeOnClick(event, treeId, treeNode) {       //第二步
            var treeObj = $.fn.zTree.getZTreeObj("treeDemo"),
                nodes = treeObj.getCheckedNodes(true),
                v = "";
            for (var i = 0; i < nodes.length; i++) {
                v += nodes[i].name + ",";
                console.log("节点id:" + nodes[i].id + "节点名称" + v); //获取选中节点的值
            }
        }

很简单，分两步即可实现，详见代码！
