Jquery EasyUI后台实例
首先是一个布局
左边是个Accordion
右边主要区域是Tabs
还有个例子很典型的左右结构:左边树(Tree),右边表格(datagrid)
ok,代码如下:
1.主页代码

using System;
using System.Web;
using System.Data;
public class GetClassJsonByPid : IHttpHandler {
public void ProcessRequest (HttpContext context) {
context.Response.ContentType = "text/plain";
string sJsonTree = string.Empty;
int parentId = -1;

if (!string.IsNullOrEmpty(pid))
Int32.TryParse(pid, out parentId);
if (parentId>=0)

}
public string getJsonTree(int pid)
{
string resultStr = "";
resultStr += "[";
string sqlexe = @"select * From proclass where pid=" + pid.ToString() + " order by [Order] ASC";
DataTable dt = mdb.db.GetDataTable(sqlexe);
foreach (DataRow dr in dt.Rows)
{

}
resultStr = resultStr.Substring(0, resultStr.Length - 1);

}
public Boolean bChild(string pid)
{
