97.             **</****div****>**  
98.         **</****div****>**  
99.     **</****div****>**

三、zTreeStyle.css修改添加节点按钮的图片样式

\[css\]  [view plain][]  [copy][view plain]

1.  .ztree li span.button.add \{  
2.                 **margin-left**: 2px;  
3.                 **margin-right**: \-1px;  
4.                 **background-position**: \-144px 0;  
5.                 **vertical-align**: top;  
6.             \}

四、后台代码：

\[csharp\]  [view plain][]  [copy][view plain]

1.  **protected** **void** Page\_Load(**object** sender, EventArgs e)  
2.         \{  
3.             **if** (Request.QueryString\["z"\] == "sdfww234edfsd")  
4.             \{  
5.  StringBuilder sb = **new** StringBuilder();  
6.                 sb.Append("\[");  
7.                 sb.Append("\{\\"id\\":\\"1\\",\\"name\\":\\"销售单管理\\",\\"pId\\":\\"0\\",\\"Action\\":\\"list\\"\},");  
8.                 sb.Append("\{\\"id\\":\\"2\\",\\"name\\":\\"销售单列表\\",\\"pId\\":\\"1\\",\\"Action\\":\\"list\\"\},");  
9.                 sb.Append("\]");  
10.                Response.Write(sb.ToString());  \}  
11.        \}
