下面是使用zTree异步加载的一个例子:
以下面这个Node的例子举个栗子:
var nodes =
[ { 'id': 1, 'pid': 0, 'name': '硬件规格','open':false },
{ 'id': 10, 'pid': 1, 'name': '单板', 'open':false },
//比如点击单板+,要异步加载的两个节点,模拟用
{ 'id': 100, 'pid': 10, 'name': '单板_00', 'open':false },
{'id': 101,'pid': 10,'name': '单板_01','open':false},
{'id': 11, 'pid': 1, 'name': '子卡', 'open':false },
{ 'id': 12, 'pid': 1, 'name': '设备', 'open':false},
{ 'id': 2,'pid': 0, 'name': '软件规格', 'open':false},
{'id': 20,'pid': 2, 'name': 'java', 'open':false },
{'id': 21, 'pid': 2, 'name': 'jscript', 'open':false },
{ 'id': 22, 'pid': 2, 'name': 'php','open':false }
]
实际上这个ztree的node是json数组
