一 . 在js 中使用ajax 调用后台代码方法，解析返回值
1 ajax 请求格式
$.ajax({
type: "Post",
url: "/coupons.aspx/AllVouchers",
contentType: "application/json",
data: "{'index': '" + index + "', 'status': '" + status + "'}",
dataType: 'json',
success: function (data) {
data = JSON.parse(data.d);
｝
｝);
$.ajax({
type: "Post",
url: "/coupons.aspx/AllVouchersCount",
contentType: "application/json",
data: "{ 'status': '" + status + "'}",
dataType: 'json',
success: function (data) {
data= eval("(" + data.d + ")").result;
｝
｝);
2 后台方法
//列表
public partial class coupons : System.Web.UI.Page
｛
[WebMethod]
public static string AllVouchers(string index,string status )
{
int pageindex = Convert.ToInt32(index);
int page = 9;
string uid = "";
if (HttpContext.Current.Session["uid"] == null)
{
HttpContext.Current.Response.Redirect("login.aspx");
}
else
{
uid = PubEncryptionFunc.PublicDecrypt(HttpContext.Current.Session["uid"].ToString());
}
return JsonConvert.SerializeObject(COUPON_DAIJIN.getInstanct().DsCoupon_DaiJin(uid, status, pageindex, page));
}
｝
//总计录数
[WebMethod]
public static string AllVouchersCount(string status)
{
string uid = "";
if (HttpContext.Current.Session["uid"] == null)
{
HttpContext.Current.Response.Redirect("login.aspx");
}
else
{
uid = PubEncryptionFunc.PublicDecrypt(HttpContext.Current.Session["uid"].ToString());
}
string json = "{\"result\":\""+ COUPON_DAIJIN.getInstanct().Coupon_DaiJinCount(uid, status).ToString() + "\"}";
return json ;
}
