一、客户端通过Ajax调用后台方法返回DataSet,Ilist,ilist,T,对象
后台代码
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Data;
using Xy.GamePt.VO;
using Xy.GamePt.BO;
using System.Collections;
public partial class Test : System.Web.UI.Page
{
//添加一个 AjaxPro.HttpSessionStateRequirement 枚举的值到你的 AjaxPro.AjaxMethodAttribute中.
//例如：
//[AjaxPro.AjaxMethod(AjaxPro.HttpSessionStateRequirement.Read)]
//现在你就可以像下面这样存取Session的值了: this.Session["0"].ToString().
//另外一个问题：如何在AjaxMethod中使用Cookie?
//答案是不能使用"this"的引用存取cookie ，你必须使用HttpContext.Current
//例如:
//HttpContext.Current.Request.Cookies[Name].Value.
protected void Page_Load(object sender, EventArgs e)
{
AjaxPro.Utility.RegisterTypeForAjax(typeof(Test));
}
[AjaxPro.AjaxMethod()]
public string GetServerTime()
{
System.Threading.Thread.Sleep(2000);
return DateTime.Now.ToString();
}
[AjaxPro.AjaxMethod()]
public DataSet GetDataSet()
{
DataSet ds = new DataSet();
DataTable dt = new DataTable();
dt.Columns.Add("id", typeof(int));
dt.Columns.Add("parentId", typeof(int));
dt.Columns.Add("name", typeof(string));
dt.Rows.Add(1, 0, "A-DGamename1");
dt.Rows.Add(2, 1, "A-DGamename2");
dt.Rows.Add(3, 1, "A-DGamename3");
dt.Rows.Add(4, 1, "A-DGamename4");
dt.Rows.Add(5, 0, "A-DGamename5");
dt.Rows.Add(6, 5, "A-DGamename6");
dt.Rows.Add(1, 0, "E-HGamename1");
dt.Rows.Add(2, 1, "E-HGamename2");
dt.Rows.Add(3, 1, "E-HGamename3");
dt.Rows.Add(4, 1, "E-HGamename4");
dt.Rows.Add(5, 0, "E-HGamename5");
dt.Rows.Add(6, 5, "E-HGamename6");
ds.Tables.Add(dt);
return ds;
}
[AjaxPro.AjaxMethod()]
public IList<Game> GetGameList()
{
return GameBO.GetGameList();
}
[AjaxPro.AjaxMethod()]
public Game GetGame()
{
return GameBO.GetGame();
}
/// <summary>
/// 返回Ilist
/// </summary>
/// <param name="parameter">脚本字符串参数</param>
/// <param name="arr">脚本数组参数</param>
/// <param name="xiaoxin">脚本对象参数</param>
/// <returns></returns>
[AjaxPro.AjaxMethod()]
public IList GetData(string parameter,string [] arr,object obj)
{
object xxxx = obj;
Hashtable ht = xxxx as Hashtable;
string sss = parameter;
Array aaaa = arr;
//Hashtable ht = arr as Hashtable;
return TestBO.GetIlist();
}
}

}
/* 客户端调用返回的字符串--------------------*/
function GetTime() {
// 调用服务端方法
//调用方法:类名.方法名 (参数为指定一个回调函数)
Test.GetServerTime(callback);
}
function callback(res) //回调函数,显示结果

alert(res.value);

/* 客户端调用返回的DataSet--------------------*/
function Change() {
Test.GetDataSet(change_callback)
}
function change_callback(response) {
var ds = response.value;
var content = document.getElementById("newDG");
var table = null;
for (var i = 0; i < ds.Tables[0].Rows.length; i++) {
if (i == 0) {
table = ds.Tables[0].Rows[i].name + "<br>";
}
else {
table += ds.Tables[0].Rows[i].name + "<br>";
}
}
content.innerHTML = table;
}

/* 客户端调用返回的IList--------------------*/
function GetIListData() {

function User(name, age) {
this.name = name;

this.canFly = false;
}
var obj = new User("234", "5345");

</script>
</form>
</body>

二、前台通过按钮事件调用后台方法
前台隐藏一按钮
<asp:Button ID="reuser_btn" runat="server" onclick="reuser_btn_Click" style="display:none;" />
<script>document.getElementById('<%=reuser_btn.ClientID%>').click();</script>
后台写按钮提交事件
protected void reuser_btn_Click(object sender, EventArgs e)
{
}
三、后台调用前台js方法
ScriptManager.RegisterStartupScript(this.Page, this.GetType(), "page_alert", "alert('ok')", true);
Response.Write("<script>alert('ok');</script>")
