我的情况：
我有一个 ASP.NET 按钮的问题，当我单击该按钮时它不会引发回发。
我有一个按钮，其 ID 为“PurchaseBtn”。单击此按钮时，我使用 jQuery 打开一个名为“PurchaseDiv”的面板。
不起作用的按钮是“PutInBasket”按钮。当我点击按钮时什么都没有发生，当然也没有回发。
我试过添加一个 OnClientClick="return true;" ，然后发生回发 - 但没有运行代码隐藏。因此，这也不是一个解决方案。
代码
我有以下代码：
<asp:Button ID="PurchaseBtn" runat="server" Text="Køb" />
<asp:Panel ID="PurchaseDiv" runat="server" CssClass="Popup">
<asp:HyperLink id="PopupCloseLnk" runat="server" CssClass="popupClose">x</asp:HyperLink>
<h3>Køb <asp:Label ID="LinkTypeName" runat="server"></asp:Label></h3>
<p>Ønsket URL:<br />
<asp:TextBox ID="UrlBox" runat="server" Width="250"></asp:TextBox>
<asp:RequiredFieldValidator ID="UrlReq" runat="server" ControlToValidate="UrlBox" Text="*" ForeColor="Red"></asp:RequiredFieldValidator>
</p>
<p>Antal:<br />
<asp:Textbox ID="QuantityBox" runat="server"></asp:Textbox>
<asp:NumericUpDownExtender ID="QuantityExtender" runat="server"
Width="100"
TargetControlID="QuantityBox"
Minimum="1"
Maximum="200">
</asp:NumericUpDownExtender>
</p>
<br />
<p>Anchor tekster<br />
<asp:TextBox ID="AnchorTexts" runat="server" TextMode="MultiLine">
</asp:TextBox>
<asp:TextBoxWatermarkExtender ID="AnchorTextsExtender" runat="server" WatermarkCssClass="watermarked"
TargetControlID="AnchorTexts" WatermarkText="Ikke påkrævet at udfylde" />
</p>
<asp:Button ID="PutInBasket" runat="server" Text="Put i kurv"
onclick="PutInBasket_Click" />
</asp:Panel>
<asp:Panel id="bgPopup" runat="server" CssClass="bgPopup"></asp:Panel>
以及以下 jQuery：
<script type="text/javascript">
function loadPopup() {
//loads popup only if it is disabled
if ($('#<%=bgPopup.ClientID %>').data("state") == 0) {
$('#<%=bgPopup.ClientID %>').css({
"opacity": "0.7"
});
$('#<%=bgPopup.ClientID %>').fadeIn("medium");
$('#<%=PurchaseDiv.ClientID%>').fadeIn("medium");
$('#<%=bgPopup.ClientID %>').data("state", 1);
}
}
function disablePopup() {
if ($('#<%=bgPopup.ClientID %>').data("state") == 1) {
$('#<%=bgPopup.ClientID %>').fadeOut("medium");
$('#<%=PurchaseDiv.ClientID %>').fadeOut("medium");
$('#<%=bgPopup.ClientID %>').data("state", 0);
}
}
function centerPopup() {
var winw = $(window).width();
var winh = $(window).height();
var popw = $('#<%=PurchaseDiv.ClientID%>').width();
var poph = $('#<%=PurchaseDiv.ClientID%>').height();
$('#<%=PurchaseDiv.ClientID%>').css({
"position": "absolute",
"top": winh / 2 - poph / 2,
"left": winw / 2 - popw / 2
});
//IE6
$('#<%=bgPopup.ClientID %>').css({
"height": winh
});
}
$(document).ready(function () {
var mouse_is_inside = true;
$('#<%=PurchaseDiv.ClientID%>').hover(function () {
mouse_is_inside = true;
}, function () {
mouse_is_inside = false;
});
$("body").mouseup(function () {
if (!mouse_is_inside) {
disablePopup();
}
});
$('#<%=bgPopup.ClientID %>').data("state", 0);
$('#<%=PurchaseBtn.ClientID%>').click(function () {
centerPopup();
loadPopup();
});
$('#<%=PopupCloseLnk.ClientID %>').click(function () {
disablePopup();
});
$(document).keypress(function (e) {
if (e.keyCode == 27) {
disablePopup();
}
});
});
$(window).resize(function () {
centerPopup();
});
</script>
PutInBasket 的代码隐藏
protected void PutInBasket_Click(object sender, EventArgs e) {
var purchase = BuildPurchase();
if(SessionManager.Purchases = null)
{
SessionManager.Purchases = new Purchase();
}
SessionManager.Purchases.AddPurchase(purchase);
RedirectManager.RedirectToShoppingBasket();}
