AjaxPro执行返回null

Question

.cspublic static int flag = 0;
    protected void Page_Load(object sender, EventArgs e)
    {
AjaxPro.Utility.RegisterTypeForAjax(typeof(admin_admin_News));
        if (!IsPostBack)
        {
 BindNewsClassData();
            SetBind("");
        }
    }
    [AjaxPro.AjaxMethod(AjaxPro.HttpSessionStateRequirement.ReadWrite)]
    public int News_Orders()
    {
if(flag == 0)
{
flag = 1;
SetBind("P_Name desc,");
}
else
{
flag = 0;
SetBind("P_Name asc,");
}
return flag;
    }
.aspx
function sufun()
{
alert(admin_admin_News.News_Orders().value);
alert("222");
}
执行后弹出null然后又弹出222
怎么办？

Answer 1

ajax返回值是这么使用的？应该使用函数吧
alert(admin_admin_News.News_Orders().value);
