Jquery Dialog不会立即等待用户输入和服务器端事件触发

Question

我有GirdView，Girdview内有Checkbox列。 Checkbox AutoPostback属性设置为TRUE，因为我正在对Checkbox checked州进行一些数据库工作。现在我用javascript confirm Jquery替换普通的DialogBox框。问题是当用户check出现checkbox对话框时，用户必须确认是否确保他们想要检查复选框，如果他们按yse然后复选框被选中然后我想要服务器端事件t fire。相反，当用户检查复选框和服务器端事件触发然后出现对话框时，即使他们按NO，数据库已经更新为YES，也会发生这种情况。

这是我的代码。

HTML

<asp:GridView ID="gvOrders" runat="server" AutoGenerateColumns="false"
CssClass="gvClickCollectOrders" DataKeyNames="OrderId" OnRowDataBound="gvOrders_RowDataBound"
AllowPaging="true" OnPageIndexChanging="gvOrders_PageIndexChanging">
    <Columns>
        <asp:BoundField DataField="OrderId" Visible="false" />
        <asp:BoundField DataField="OrderNumber" HeaderText="Order No" DataFormatString="WWW {0}"
        />
        <asp:TemplateField HeaderText="Order Date">
            <ItemTemplate>

的Jquery

< script type = "text/javascript" >

var isReceivedCheckBox = $('.isReceivedCheckBox input[type=checkbox]');
var isCollectedCheckBox = $('.isCollectedCheckBox input[type=checkbox]');
var def = $.Deferred();

function confirmDialog(msg) {
    var dialog = $("<div id=\"dialog\">" + msg + "</div>");
    $(dialog).dialog({
        autoOpen: true,
        width: 300,
        height: 200,
        resizable: false,
        modal: false,
        buttons: {
            'Yes': function () {
                def.resolve();
                $(this).dialog("close");
            },
                'No': function () {
                def.reject();
                $(this).dialog("close");
            }
        },
        close: function () {
            $(this).remove();
        }
    });
    return def.promise();
}

$(function () {
    $(isReceivedCheckBox).on("change", function () {
        var checked = this.checked;
        var checkbox = this;
        if (checked) {
            confirmDialog("are your sure you want to check this checkbox?").done(function () {
                checkbox.checked = true;
            })
                .fail(function () {
                checkbox.checked = false;
            });
        } else {
            confirmDialog("are your sure you want to uncheck this checkbox?").done(function () {
                checkbox.checked = false;

不确定是否有其他方法，但您可以手动进行回发。 设置AutoPostBack = false并使用__doPostBack函数。
