JS调用Webservice，并处理返回的XML数据

如果在系统中只需要用到一个很简单的无刷新功能，那么没有必要使用庞大的AJAX框架，直接用JS调用Webservice来实现即可：

 

 1       现货信息发送#region 现货信息发送
 2        [WebMethod(true)]
 3        public string CreatePrice(string productid, string PLprice, string PHprice,string marketid)
 4        {
 5            string revalue = "0";
 6            string[] _pidList = productid.Split(',');
 7            string[] _plprice = PLprice.Split(',');
 8            string[] _phprice = PHprice.Split(',');
 9            DataSet ds = SmsProductEntityAction.Get_SmsProductAll(marketid);
            DataTable tb;
            string marketname = MarketEntityAction.Get_MarketModel(marketid).MarketName;
            string msg = "";
            if (ds.Tables.Count >= 1)
            {
                for (int i = 0; i < _pidList.Length; i++)
                {
                    if (_plprice[i].Trim() != "")
                    {
                        DataRow[] row = ds.Tables[0].Select("ProductId='" + _pidList[i] + "'");
                        if (row.Length >= 1)
                        {
                            string _AttId = row[0]["AttributeID"].ToString();
                            msg += PriceGroup.AlertPriceEntity(int.Parse(_AttId), _plprice[i].ToString(), _phprice[i].ToString(), row[0]["ProductName"].ToString());
                        }
                    }
                }
                if (msg == "")
                {
                    tb = PriceGroup.CreateDataTable();
                    ArrayList al = new ArrayList(200);
                    for (int i = 0; i < _pidList.Length; i++)
                    {
                        string lp = _plprice[i].ToString();
                        string hp = _phprice[i].ToString();
                        string pid = _pidList[i].ToString();
                        if (lp.Trim() != "")
                        {
                            DataRow[] row = ds.Tables[0].Select("ProductId='" + pid + "'");
                            if (row.Length >= 1)
                            {
                                string AttId = row[0]["AttributeID"].ToString();
                                PriceEntity _Pe = PriceGroup.SetPriceEntity(int.Parse(AttId), lp, hp, pid, marketid);
                                PriceGroup.ConvertToDataTable(tb, _Pe);
                            }
                            al.Add(pid);
                        }
                    }
                    int _flag = PriceEntityAction.create_Price(tb);
                    if (_flag != 0)
                    {
                        revalue = "数据没有正确存储，请重新提交！";
                        //MessageBox.MsgShow(this, "数据没有正确存储请重新提交！");
                    }
                    else
                    {
                        Guid gi = Guid.NewGuid();
                        Session[gi.ToString()] = al;
                        revalue = "index.aspx?Subid=31&marketname=" + marketname + "&marketid=" + marketid + "&guid=" + gi.ToString();
                        //HttpContext.Current.Response.Redirect("index.aspx?Subid=31&marketname=" + marketname + "&marketid=" + marketid + "&guid=" + gi.ToString() + "");
                    }
                }
                else
                {
                    revalue = msg + "\n请查检您的输入是否正确！\n";
                    //msg += "\\r\\n请查检您的输入是否正确！\\n";
                    //MessageBox.MsgShow(this, msg);
                }
            }
            return revalue;
        }
        #endregion

 

下面是JS代码：

 

 1 var productid = new Array();//产品ID
 2 var PLprice = new Array();//最低价
 3 var PHprice = new Array();//最高价
 4 var pname = new Array();//产品名称
 5 
 6 function MaxMin_OnClick(oLnk, sContentID)
 7 {

         pname[i] = document.getElementById(productid[i]).innerText;
     }

另外，httprequest默认不支持GET方式，需要在配置文件里面修改才行
