我正在创建一个网上商店，在该网上商店中单击产品时，我使用带有 iframe 的fancybox 来显示产品的详细信息页面。

在产品的详细信息页面中，您可以通过 AJAX 调用购买产品。该调用将购买发送到数据库并更新购物车金额。

但是，当我第一次单击购买按钮时，iframe 只是刷新。从第二次开始，按钮就可以正常工作了，但我不能再关闭fancybox了（既不能通过单击关闭按钮，也不能通过使用代码）。我也没有收到任何 javascript 错误，并且在自行打开产品详细信息页面（而不是在花哨的框中）时，一切正常。

由于我在任何地方都没有出现任何错误，并且没有fancybox，一切都可以正常工作，所以我真的不知道应该放哪段代码。

Fwiw 我正在运行 jquery 版本 1.8.3 和 fancybox 版本 1.3.4

编辑：这是相关代码

打开我的fancybox的javascript函数

function ShowAssetDetail(lngAssetID) {
    $.fancybox(
    {
        'modal': false,
        'width': 500,
        'height': 500,
        'autoscale': false,
        'type': 'iframe',
        'href': '/Code/Webshop/WS_Detail_Layout_2.asp?AssetID=' + lngAssetID
    });
}

在 fancybox 中显示的 iframe

<div name="SHOPPINGCART" id="SHOPPINGCART" border="1">
<table class="ShoppingCart" title="Naar het detail van uw winkelmandje / Naar de kassa">
    <tr>
        <td>
            <a href="/Code/Webshop/WS_Order_Detail.asp?"> 
                €&amp;nbsp;96,00
            </a>
        </td>
        <td>
            <a href="/Code/Webshop/WS_Order_Detail.asp?"> 
                <img src="/code/_Images/WS_basket_go.gif" width="16" height="16" border="0" title=""> 
            </a>
        </td>
    </tr>
</table>
</div>

<table class="AssetDetail_BuyAsset_Table" cellspacing="0" cellpadding="3px" width="100%">
<tr class="TableHeading1">       
    <td>P. iBTW</td>
    <td colspan="2">&nbsp;</td>
</tr>
<tr class="Normal_Text_1">           
    <td>€&amp;nbsp;25,00</td>        
    <td><input type="text" name="X_PurchaseQuantity" id="X_PurchaseQuantity" size="5" value="3" onclick="this.select()">
    <td><a href="#AddProductToShoppingCart" onclick="AddProductToShoppingCart(X,Y,document.getElementById('X_PurchaseQuantity').value,Z)"><img src="/code/_Images/WS_basket_add.gif" border="0"></a></td>      
</tr> 
</table>

javascript 函数和 AJAX 调用
