Shopping cart -fly to basket in asp.net and dhtml

[Shanthini Ganesh]

hi all. now i m creating shopping cart. i would like to make when the user click the add to basket button, item added visually shown to user. i found one script for this in net.. but i couldnt pass dynamic productid to that addtobasket javascript function.
this is my function..
function addToBasket(productId)
{
if(!shopping_cart_div)shopping_cart_div = document.getElementById('shopping_cart');
if(!flyingDiv){
flyingDiv = document.createElement('DIV');
flyingDiv.style.position = 'absolute';
document.body.appendChild(flyingDiv);
}

shopping_cart_x = shoppingCart_getLeftPos(shopping_cart_div);
shopping_cart_y = shoppingCart_getTopPos(shopping_cart_div);

currentProductDiv = document.getElementById('slidingProduct' + productId);

currentXPos = shoppingCart_getLeftPos(currentProductDiv);
currentYPos = shoppingCart_getTopPos(currentProductDiv);

diffX = shopping_cart_x - currentXPos;
diffY = shopping_cart_y - currentYPos;



var shoppingContentCopy = currentProductDiv.cloneNode(true);
shoppingContentCopy.id='';
flyingDiv.innerHTML = '';
flyingDiv.style.left = currentXPos + 'px';
flyingDiv.style.top = currentYPos + 'px';
flyingDiv.appendChild(shoppingContentCopy);
flyingDiv.style.display='block';
flyingDiv.style.width = currentProductDiv.offsetWidth + 'px';
flyToBasket(productId);

}
this is my asp.net code


<asp:DataList ID="dlstProductDetails" runat="server" RepeatDirection="Horizontal" RepeatColumns="3" HorizontalAlign="Center" style="text-align: center" Width="100%" SkinID="DataList" >
<ItemTemplate>
<div id="slidingProduct+dynamicvalue" class="sliding_product"><asp:ImageButton ID="imgbtnProductImage" runat="server" ImageUrl='<%#"images.aspx?id=" + Eval("ProductNo")%>' Height="100" Width="100" Commandname='<%#DataBinder.Eval(Container.DataItem , "ProductNo")%>' OnCommand="Filterdescription"/>
<br/>
<asp:Label ID="lblProductName" runat ="server" Text ='<%#DataBinder.Eval(Container.DataItem, "Productname")%>'></asp:Label>
<asp:Label ID="lblHyp" runat="server" text=" - " ForeColor="#ff8000"/>
<asp:Label ID="lblModelNo" runat ="server" Text ='<%#DataBinder.Eval(Container.DataItem, "ModelNo")%>'></asp:Label>

<br />
<a href="#" onclick="addToBasket(productno);return false;"><img src="images/basket.gif"></a>
