Sharepoint2010使用AJAx 获取 OData Service (实现客户端获取sharepoint2010的数据)---第一篇

 

我们在做Sharepoint2007时,习惯于用对项目模型来获取数据,但都是后台代码,和客户端不能很好的互动,感觉很不爽,今天我来迎来了Sharepoint2010,它带来了客户端对象模型,听名字就知道干什么的呢,但今天我们不是讲客户端对象模型,还是另一种方式获取Sharepoint数据源,那就是 OData Service 。

 

(一) 使用OData Service  的前提得必须要安装一个补丁,叫做“ADO.NET Data Services Update for .NET Framework 3.5 SP1 for Windows 7 and Windows Server 2008 R2” ,安装好后重启,然后打开“http://mySite/_vti_bin/ListData.svc ”,(mySite)是自己的站点,你可以看到自己站点上所有的列表信息,如果你要看某一个列表的数据,则打开这个地址“http://mySite/_vti_bin/ListData.svc/myListName” 。

 

(二)你要使用AJAX获取OData Service ,则需要安装AJAX控件工具包源代码(我用的是AjaxControlToolkit.Source.zip),然后把其中的几个文件按下面的方法放置:

 

  •  复制  AjaxControlToolkit.Source\SampleWebSites\AjaxClientWebSite\Scripts;  到    C:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\ \14\TEMPLATE\LAYOUTS\Scripts
  • 复制 AjaxControlToolkit.Source\Client\MicrosoftAjax\Templates; 到    C:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\ \14\TEMPLATE\LAYOUTS\Scripts

     

    (三)写代码(用VS2010 创建一个Sharepoint空项目,然后创建一个页面)

     

    代码
        
          
    <% @ Assembly Name = " $SharePoint.Project.AssemblyFullName$ " %>
    <% @ Import Namespace = " Microsoft.SharePoint.ApplicationPages " %>
    <% @ Register Tagprefix = " SharePoint " Namespace = " Microsoft.SharePoint.WebControls " Assembly = " Microsoft.SharePoint, Version=14.0.0.0, Culture=neutral, PublicKeyToken=71e9bce111e9429c " %>
    <% @ Register Tagprefix = " Utilities " Namespace = " Microsoft.SharePoint.Utilities " Assembly = " Microsoft.SharePoint, Version=14.0.0.0, Culture=neutral, PublicKeyToken=71e9bce111e9429c " %>
    <% @ Register Tagprefix = " asp " Namespace = " System.Web.UI " Assembly = " System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35 " %>
    <% @ Import Namespace = " Microsoft.SharePoint " %>
    <% @ Assembly Name = " Microsoft.Web.CommandUI, Version=14.0.0.0, Culture=neutral, PublicKeyToken=71e9bce111e9429c " %>
    <% @ Page Language = " C# " AutoEventWireup = " true " CodeBehind = " UserStories.aspx.cs " Inherits = " PreDemo.Layouts.PreDemo.UserStories " DynamicMasterPageFile = " ~masterurl/default.master " %>

    < asp:Content ID = " PageHead " ContentPlaceHolderID = " PlaceHolderAdditionalPageHead " runat = " server " >
    < style type = " text/css " >
    .sys
    - template
    {
    display:none;
    }
    < / style>
    < script src = " /_layouts/Scripts/MicrosoftAjax/Start.js " type = " text/javascript " >< / script>
    < script src = " /_layouts/Scripts/MicrosoftAjax/MicrosoftAjax.js " type = " text/javascript " >< / script>
    < script type = " text/javascript " >
    Sys.require([
    Sys.components.dataView,
    Sys.components.openDataServiceProxy,
    Sys.scripts.jQuery
    ]);
    Sys.onReady(
    function () {
    var dataSource = Sys.create.openDataServiceProxy( ' /_vti_bin/ListData.svc ' );


    Sys.query(
    " #userStoriesList " ).dataView({
    dataProvider: dataSource,
    fetchOperation:
    " Tasks " ,
    feachParameters: { orderby:
    ' 标题 ' },
    autoFetch:
    " true "
    });

    });
    < / script>
    < / asp:Content>
    < asp:Content ID = " Main " ContentPlaceHolderID = " PlaceHolderMain " runat = " server " >
    Hello World
    !
    < ul id = " userStoriesList " class = " sys-template " >
    < li > {{ 标题 }} < / li>
    < / ul>
    < / asp:Content>
    < asp:Content ID = " PageTitle " ContentPlaceHolderID = " PlaceHolderPageTitle " runat = " server " >
    应用程序页
    < / asp:Content>
    < asp:Content ID = " PageTitleInTitleArea " ContentPlaceHolderID = " PlaceHolderPageTitleInTitleArea " runat = " server " >
    我的应用程序页
    < / asp:Content>

    Tasks是我的任务列表,<li>{{ 标题 }}</li> 是绑定数据

     最后一个要注意的是sys-template类。这是一个在ASP.Net AJAX中预定义的CSS类,当完成渲染工作后,由ASP.Net AJAX将其设置为display:block。因此,我们需要为sys-template创建一个CSS类并设为display:none,这样在页面加载过程中最终用户就看不到你的模板代码了。

    (四)最后,你按F5部署到站点上,就可以看见自己的数据了。

     

    下次还要写AJAX如何运用这些数据实现很炫的效果。
