3.{"id":11, "name":"test11", "nodes":[

4.{"id":111, "name":"test111"}

5."id":12, "name":"test12"}

Array

格式

(isSimpleData)的zTreeNodes

举例：

Js代码

1.var treeNodes = [

2. {"id":1, "pId":0, "name":"test1"},

3.{"id":11, "pId":1, "name":"test11"},

4. {"id":12, "pId":1, "name":"test12"},

5. {"id":111, "pId":11, "name":"test111"},

zTree的js和css：

Html代码

3.<!-- <link rel="stylesheet" href="<%=root%>/Web/common/css/zTreeStyle/zTreeIcons.css" type="text/css"> -->

<br><SPAN><IMG id="Image_Closed" style="DISPLAY: none" onclick="this.style.display='none'

Text_Closed.style.display='inline'

Image_Open.style.display='inline'

Text_Open.style.display='inline'"

src="pic/m_o.gif"><IMG id="Image_Open<%= i %>" onclick="this.style.display='none'

Image_Closed.style.display='inline'

Text_Open.style.display='none'
