楼下说方法。

第一步：在调用页面的模板增加如下代码：

                <div id="basketItemsWrap">

                </div>

<div style="height:30px;" id="shopbt">

<ul id='shopcart_bottom'><li><a href='/shop/payment.asp' ><img src='/shop/images/hesuan.gif'/></a></li><li><a href='/shop/shoppingcart.asp' ><img src='/shop/images/chakangouwuche.gif'/></a></li></ul>

</div>

注意：代码和JS是严格匹配的，修改代码标识后记得修改JS。

页面顶端增加JS如下：

<script>

$(document).ready(function(){

$.ajax({

  type:'POST',

  url:'/Plus/Ajaxs.asp',

  data:{pram:"show",Action:"addcart1"}, //初始化购物车内容

  success:function(theResponse){

   if($("#productID_").length<=0 && theResponse!=""){ //初始化购物车。

    $("#basketItemsWrap").html(theResponse);

   

   

    }

   }

  });





   $("#basketItemsWrap .pjian").live("click", function(event) {

  var PidSplitter=(this.id).split("_");

  var Pid=PidSplitter[1];

  $("#notificationsLoader").html('<img src="/images/loading.gif">');

  $.ajax({

   type:'POST',

   url:'/plus/Ajaxs.asp',

   data:{pid:Pid,Action:"addcart1",Pact:"jian"},

   success:function(theResponse){

     $("#basketItemsWrap table").remove();

     $("#basketItemsWrap").html(theResponse);

     $("#notificationsLoader").empty();  

    }

   })

  

  });

  

   $("#basketItemsWrap .pdel").live("click", function(event) {

  var PidSplitter=(this.id).split("_");

  var Pid=PidSplitter[1];

  $("#notificationsLoader").html('<img src="/images/loading.gif">');

  $.ajax({

   type:'POST',

   url:'/plus/Ajaxs.asp',

   data:{pid:Pid,Action:"addcart1",Pact:"del"},

   success:function(theResponse){

     $("#basketItemsWrap table").remove();

     $("#basketItemsWrap").html(theResponse);

     $("#notificationsLoader").empty();  

    }

   })

  

  });

  

   $("#basketItemsWrap .pjia").live("click", function(event) {

  var PidSplitter=(this.id).split("_");

  var Pid=PidSplitter[1];

  $("#notificationsLoader").html('<img src="/images/loading.gif">');

  $.ajax({

   type:'POST',

   url:'/plus/Ajaxs.asp',

   data:{pid:Pid,Action:"addcart1"},

   success:function(theResponse){

     $("#basketItemsWrap table").remove();

     $("#basketItemsWrap").html(theResponse);

     $("#notificationsLoader").empty();  

    }

   })

  

  });





$(".addcart").click(function(){

  var ProductIdValSplitter=(this.id).split("_");

  var ProductIdVal=ProductIdValSplitter[1];

  $("#notificationsLoader").html('<img src="/images/loading.gif">');

  $.ajax({

   type:'POST',

   url:'/Plus/Ajaxs.asp',

   data:{pid:ProductIdVal,Action:"addcart1"},

   success: function(theResponse){

     if (theResponse=='error'){

     $("#notificationsLoader").empty();            

          alert('对不起，您没有登录!');

     }else if (theResponse=='error1'){

     $("#notificationsLoader").empty();            

          alert('对不起，您所在的用户级别不能购买本商品!');

      

     }else if (theResponse=='error2'){

     $("#notificationsLoader").empty();            

          alert('对不起，网站不允许游客订餐，请注册会员!');

     }else{

      

     $("#basketItemsWrap table").remove();

     $("#basketItemsWrap").html(theResponse);

     $("#notificationsLoader").empty();  

         

     }

   

    }

   });

  });

});



</script>

第二步：修改AJAx后台文件/plus/ajaxs.asp,增加红色代码

Case "relativeDoc" relativeDoc

Case "getModelType" getModelType

Case "addCart" addShoppingCart

Case "GetPackagePro" GetPackagePro

Case "GetSupplyContact" GetSupplyContact

Case "HitsGuangGao" HitsGuangGao

Case "GetClubBoardOption" GetClubBoardOption

Case "getclubboard" GetClubboard

Case "GetClubPushModel" GetClubPushModel

Case "getclubboardcategory" getclubboardcategory

Case "getonlinelist" getonlinelist

Case "addcart1" addcart

修改函数

Function GetUserID()

    If KS.IsNul(KS.C("UserName")) Then

     If Not KS.IsNul(KS.C("CartID")) Then

      GetUserID=KS.C("CartID")

     Else

      Response.Cookies(KS.SiteSn)("CartID")=KS.MakeRandom(15)

      GetUserID=KS.C("CartID")

     End If

    Else

     GetUserID=KS.C("UserName")

    End If

End Function

添加两个函数

sub showcart()

   Set RS=Server.CreateObject("ADODB.RECORDSET")

   RS.Open "Select i.id,i.title,i.GroupPrice,i.Price_Member,i.Price,c.attr,c.amount from KS_Product i Inner Join KS_ShoppingCart c on i.id=c.proid where c.flag=0 and c.username='" & GetUserID & "'  and i.verific=1 order by i.id desc",conn,1,1

      if rs.recordcount=0 then ks.die "":response.End()

   str="<table  border='1' cellspacing='0' cellpadding='0' style='border-collapse:collapse;' align='center' ><tr><th><font color=brown>菜名</font></th><th width='65'>数量</th><th width='50'>价格</th></tr>"

   n=1

    Do While Not RS.Eof

  IF KS.C("UserName")<>"" Then

    If RS("GroupPrice")=0 Then

     RealPrice=RS("Price_Member")

    Else

     Dim RSP:Set RSP=Conn.Execute("Select Price From KS_ProPrice Where GroupID=(select groupid from ks_user where username='" & KS.C("UserName") & "') And ProID=" & RS("ID"))

     If RSP.Eof Then

    RealPrice=RS("Price_Member")

     Else

    RealPrice=RSP(0)

     End If

     RSP.Close:Set RSP=Nothing

    End If

  Else

    RealPrice=RS("Price")

  End If

  str=str&"<tr id='productID_"&rs("id")&"'><td><font color=brown>" & rs(1) & "</font></td><td width='65'><img src='/images/-.png' class='pjian' id=""productjian_"&rs("id")&""" style='cursor:hand;' /> "&rs("amount")&" <img src='/images/+.jpg' class='pjia' id='productjia_"&rs("id")&"' style='cursor:hand;'/>  <a href='#' onclick='return false;' class='pdel'  id='proddel_"&rs("id")&"'><font color=red>删</font></a></td><td width='50'>￥" & RealPrice*rs("amount") & "</td></tr>"

  n=n+1

    RS.MoveNext

    Loop

    rs.close:set rs=nothing

    str=str&"</table>"

    ks.die str

   

end sub

Sub addcart()

Dim Prodid:Prodid=KS.ChkClng(request("pid"))

Dim ProductList:ProductList=Session("ProductList")

Dim Num:Num=KS.ChkClng(request("num"))

Dim Attr:Attr=KS.DelSQL(UnEscape(Request("AttributeCart")))

if Num=0 then Num=1

Dim Pram:Pram=ks.s("pram")

Dim pact:pact=ks.s("pact")

if Pram="show" then

call showcart()

response.End()   

end if

if pact="jian" then

   Dim RSA:Set RSA=Server.CreateObject("ADODB.RECORDSET")

   rsA.open "select * from KS_ShoppingCart where flag=0 and attr='" & attr & "' and username='" & GetUserID & "' And proid=" & Prodid,conn,1,3



   if not (rsa.eof and rsa.bof)  then

       if rsa("amount")>1 then

      rsa("amount")=rsa("amount")-1

      else

      rsa.delete

      end if

      rsa.update

      

end if

rsa.close

set rsa=nothing

call showcart()

response.End()

end if

if pact="del" then

conn.execute(" delete from KS_ShoppingCart where flag=0 and attr='" & attr & "' and username='" & GetUserID & "' And proid=" & Prodid)

call showcart()

response.End()

end if

if Prodid=0 then KS.Die ""

SqlStr = "select * from KS_Config"

   Set RS = KS.InitialObject("ADODB.recordset")

   RS.Open SqlStr, Conn, 1, 3

   

    Dim Setting:Setting=Split(RS("Setting")&"^%^^%^^%^^%^^%^^%^^%^^%^^%^^%^^%^^%^^%^^%^^%^^%^^%^^%^^%^^%^^%^^%^^%^^%^^%^^%^^%^^%^^%^^%^^%^^%^^%^^%^^%^^%^^%^^%^^%^^%^^%^^%^^%^^%^^%^^%^^%^^%^","^%^")

  RS.Close:Set RS=Nothing

     Set KSUser=New UserCls

     LoginTF=KSUser.UserLoginChecked



if LoginTF=false and Setting(63)=0 then

ks.die "error2"

end if



   Set RS=Server.CreateObject("ADODB.RECORDSET")

   RS.Open "select top 1 arrGroupID From KS_Product Where id=" & Prodid,conn,1,1

   If RS.Eof And RS.Bof Then

      RS.Close : Set RS=Nothing

   ks.die "该商品不存在！"

   End If

   arrGroupID=RS(0)

   If Not KS.IsNul(arrGroupID) Then

     Set KSUser=New UserCls

     LoginTF=KSUser.UserLoginChecked

  if logintf=fasle then

   ks.die "error"

  RS.Close:Set RS=Nothing

  end if

     If KS.FoundInArr(arrGroupID,KSUser.GetUserInfo("GroupID"),",")=false Then

   RS.Close:Set RS=Nothing

   ks.die "error1"

  End If

   End If

   RS.Close  '购买验证完毕

   Set RSA=Server.CreateObject("ADODB.RECORDSET")

   rsA.open "select * from KS_ShoppingCart where flag=0 and attr='" & attr & "' and username='" & GetUserID & "' And proid=" & Prodid,conn,1,3



   if rsa.recordcount=0 then

      rsa.addnew

      rsa("flag")=0

      rsa("proid")=Prodid

      rsa("username")=GetUserID

      rsa("attr")=attr

      rsa("adddate")=now

      rsa("amount")=Num

      rsa.update

else

      rsa("amount")=rsa("amount")+1

      rsa.update

end if

rsa.close

set rsa=nothing



call showcart()

end sub

第三步：修改调用标签

增加订购按钮

<a href="{@linkurl}" id="featuredProduct_{@id}" class="addcart"><img src="/images/buy.jpg"  /></a>
