Jquery UI和asp.net母版页面

Question

有人能告诉我为什么这个代码工作没有母版页拒绝工作，当我使用嵌套母版页。基本母版页

中已经引用了必要的jquery js文件。

<%@ Page Title="" Language="C#" MasterPageFile="~/Detail.master" AutoEventWireup="true"
    CodeBehind="FieldWorkerDetail.aspx.cs" Inherits="FoodVault.Web.WebForms.Admin.FieldWorkerDetail" %>

                modal: true,
                buttons: {
                    Ok: function () {
                        $(this).dialog("close");
                    }
                }
            });
            $("#dialog-message").dialog("open");
        }

检查如何引用库。它们是本地的还是从CDN加载的?我会使用Google的CDN

<script type="text/javascript"  src="//ajax.googleapis.com/ajax/libs/jquery/1.6.2/jquery.min.js"></script>
<script type="text/javascript"  src="//ajax.googleapis.com/ajax/libs/jqueryui/1.8.15/jquery-ui.min.js"></script>

为什么你应该使用CDN: http://encosia.com/2008/12/10/3-reasons-why-you-should-let-google-host-jquery-for-you/

还有另一篇关于Master Pages的好文章:http://odetocode.com/Articles/450.aspx

如果你正在使用本地引用，请查看这个问题以确保库被正确引用。
