为什么我的jQuery的UI模式对话框立即消失，它会打开后？

问题描述

我试图用一个简单的jQuery的UI模式对话框作为在ASP.NET C＃应用程序删除确认。我已经做过很多次，但由于某种原因在此应用中它是行为不端。我看到对话框弹出，然后立即消失之前，我可以点击任一是或否。下面是相关的code（JavaScript）的：

I'm trying to use a simple jquery-ui modal dialog as a delete confirmation in an ASP.NET C# application. I've done this many times before, but for some reason in this application it is misbehaving. I see the dialog pop up then it immediately disappears before I can click on either "Yes" or "No". Here's the relevant code (Javascript):

    <script type="text/javascript" src="/resources/jquery-1.8.2.min.js"></script>
    <script type="text/javascript" src="/resources/jquery-ui-1.9.1.custom.min.js"></script>

    <link rel="stylesheet" type="text/css" href="/resources/ui-lightness/jquery-ui-1.9.1.custom.css" />

    <script type="text/javascript">
        var remConfirmed = false;
        function ConfirmRemoveDialog(obj, title, dialogText) {
            if (!remConfirmed) {
                //add the dialog div to the page
                $('body').append(String.Format("<div id='confirmRemoveDialog' title='{0}'><p>{1}</p></div>", title, dialogText));
                //create the dialog
                $('#confirmRemoveDialog').dialog({
                    modal: true,
                    resizable: false,
                    draggable: false,
                    close: function(event, ui) {
                        $('body').find('#confirmRemoveDialog').remove();
                    },
                    buttons:
                    {
                        'Yes, remove it': function() {
                            $(this).dialog('close');
                            remConfirmed = true;
                            if (obj) obj.click();
                        },
                        'No, keep it': function() {
                            $(this).dialog('close');
                        }
                    }
                });
            }

            return remConfirmed;
        }

        //String.Format function (since Javascript doesn't have one built-in
        String.Format = function() {
            var s = arguments[0];
            for (var i = 0; i < arguments.length - 1; i++) {
                var reg = new RegExp("\\{" + i + "\\}", "gm");
                s = s.replace(reg, arguments[i + 1]);
            }
            return s;
        }
    </script>

在此处，我使用的确认功能（中的一个的OnClientClick ＆LT; ASP：按钮＆GT; 控制）：

    <asp:Button ID="btnRemoveProgram" runat="server" Text="Remove" CausesValidation="false" OnClientClick="ConfirmRemoveDialog(this, 'Please confirm removal', 'Are you sure you wish to remove the selected Program? This cannot be undone.');" />

正如我所说的，我已经成功地使用同样的构造（几乎相同code）很多次;我不知道为什么它不工作了。任何想法将大大AP preciated，我真的难倒在这一个。

As I said, I've successfully used this same construct (nearly identical code) many times before; I don't know why it isn't working now. Any ideas will be greatly appreciated, I'm truly stumped on this one.

推荐答案

您需要收益的remConfirmed到这是按钮本身的调用者。在您的按钮，这样做：

You need to return the remConfirmed to the caller which is the button itself. On your button, do this:

OnClientClick="return ConfirmRemoveDialog(/* the rest of the code */);"
