Question

我想为我的网站创建图片幻灯片，例如特色网站下的此网站http://www.martynrussell.co.uk/default3.aspx?MenuID=1。

此图片的内容是动态的。有时整个内容会发生变化，或者某些时候位置属性会发生变化。

我能够让内容充满活力。

图片来自body onLoad，就像这样。

<body id="pageid1" onload="SetupFeaturedProperty(1,['http://www.brightlogic-estateagents.co.uk/MRUS/upload/1076-1.jpg', 'http://www.brightlogic-estateagents.co.uk/MRUS/upload/1076-2.jpg', 'http://www.brightlogic-estateagents.co.uk/MRUS/upload/1076-3.jpg', 'http://www.brightlogic-estateagents.co.uk/MRUS/upload/1076-4.jpg']);SetupFeaturedProperty(2,['http://www.brightlogic-estateagents.co.uk/MRUS/upload/122-1.jpg', 'http://www.brightlogic-estateagents.co.uk/MRUS/upload/122-2.jpg', 'http://www.brightlogic-estateagents.co.uk/MRUS/upload/122-3.jpg', 'http://www.brightlogic-estateagents.co.uk/MRUS/upload/122-4.jpg']);SetupFeaturedProperty(3,['http://www.brightlogic-estateagents.co.uk/MRUS/upload/38-1.jpg', 'http://www.brightlogic-estateagents.co.uk/MRUS/upload/38-2.jpg', 'http://www.brightlogic-estateagents.co.uk/MRUS/upload/38-3.jpg', 'http://www.brightlogic-estateagents.co.uk/MRUS/upload/38-4.jpg']);SetupFeaturedProperty(4,['http://www.brightlogic-estateagents.co.uk/MRUS/upload/918-1.jpg', 'http://www.brightlogic-estateagents.co.uk/MRUS/upload/918-2.jpg', 'http://www.brightlogic-estateagents.co.uk/MRUS/upload/918-3.jpg', 'http://www.brightlogic-estateagents.co.uk/MRUS/upload/918-4.jpg']);SetupFeaturedProperty(5,['http://www.brightlogic-estateagents.co.uk/MRUS/upload/1039-1.jpg', 'http://www.brightlogic-estateagents.co.uk/MRUS/upload/1039-2.jpg', 'http://www.brightlogic-estateagents.co.uk/MRUS/upload/1039-3.jpg', 'http://www.brightlogic-estateagents.co.uk/MRUS/upload/1039-4.jpg']);">

现在我的问题是如何将此分配给主页上载。因为图像顺序正在动态变化。

昨天图像顺序是这样的。

<body id="pageid1" onload="SetupFeaturedProperty(1,['http://www.brightlogic-estateagents.co.uk/MRUS/upload/918-1.jpg', 'http://www.brightlogic-estateagents.co.uk/MRUS/upload/918-2.jpg', 'http://www.brightlogic-estateagents.co.uk/MRUS/upload/918-3.jpg', 'http://www.brightlogic-estateagents.co.uk/MRUS/upload/918-4.jpg']);SetupFeaturedProperty(2,['http://www.brightlogic-estateagents.co.uk/MRUS/upload/665-1.jpg', 'http://www.brightlogic-estateagents.co.uk/MRUS/upload/665-2.jpg', 'http://www.brightlogic-estateagents.co.uk/MRUS/upload/665-3.jpg', 'http://www.brightlogic-estateagents.co.uk/MRUS/upload/665-4.jpg']);SetupFeaturedProperty(3,['http://www.brightlogic-estateagents.co.uk/MRUS/upload/38-1.jpg', 'http://www.brightlogic-estateagents.co.uk/MRUS/upload/38-2.jpg', 'http://www.brightlogic-estateagents.co.uk/MRUS/upload/38-3.jpg', 'http://www.brightlogic-estateagents.co.uk/MRUS/upload/38-4.jpg']);SetupFeaturedProperty(4,['http://www.brightlogic-estateagents.co.uk/MRUS/upload/122-1.jpg', 'http://www.brightlogic-estateagents.co.uk/MRUS/upload/122-2.jpg', 'http://www.brightlogic-estateagents.co.uk/MRUS/upload/122-3.jpg', 'http://www.brightlogic-estateagents.co.uk/MRUS/upload/122-4.jpg']);SetupFeaturedProperty(5,['http://www.brightlogic-estateagents.co.uk/MRUS/upload/1076-1.jpg', 'http://www.brightlogic-estateagents.co.uk/MRUS/upload/1076-2.jpg', 'http://www.brightlogic-estateagents.co.uk/MRUS/upload/1076-3.jpg', 'http://www.brightlogic-estateagents.co.uk/MRUS/upload/1076-4.jpg']);">

今天的图像顺序是这样的

<body id="pageid1" onload="SetupFeaturedProperty(1,['http://www.brightlogic-estateagents.co.uk/MRUS/upload/1076-1.jpg', 'http://www.brightlogic-estateagents.co.uk/MRUS/upload/1076-2.jpg', 'http://www.brightlogic-estateagents.co.uk/MRUS/upload/1076-3.jpg', 'http://www.brightlogic-estateagents.co.uk/MRUS/upload/1076-4.jpg']);SetupFeaturedProperty(2,['http://www.brightlogic-estateagents.co.uk/MRUS/upload/122-1.jpg', 'http://www.brightlogic-estateagents.co.uk/MRUS/upload/122-2.jpg', 'http://www.brightlogic-estateagents.co.uk/MRUS/upload/122-3.jpg', 'http://www.brightlogic-estateagents.co.uk/MRUS/upload/122-4.jpg']);SetupFeaturedProperty(3,['http://www.brightlogic-estateagents.co.uk/MRUS/upload/38-1.jpg', 'http://www.brightlogic-estateagents.co.uk/MRUS/upload/38-2.jpg', 'http://www.brightlogic-estateagents.co.uk/MRUS/upload/38-3.jpg', 'http://www.brightlogic-estateagents.co.uk/MRUS/upload/38-4.jpg']);SetupFeaturedProperty(4,['http://www.brightlogic-estateagents.co.uk/MRUS/upload/918-1.jpg', 'http://www.brightlogic-estateagents.co.uk/MRUS/upload/918-2.jpg', 'http://www.brightlogic-estateagents.co.uk/MRUS/upload/918-3.jpg', 'http://www.brightlogic-estateagents.co.uk/MRUS/upload/918-4.jpg']);SetupFeaturedProperty(5,['http://www.brightlogic-estateagents.co.uk/MRUS/upload/1039-1.jpg', 'http://www.brightlogic-estateagents.co.uk/MRUS/upload/1039-2.jpg', 'http://www.brightlogic-estateagents.co.uk/MRUS/upload/1039-3.jpg', 'http://www.brightlogic-estateagents.co.uk/MRUS/upload/1039-4.jpg']);">

请建议我如何管理这个。如何在运行时分配值？

感谢。

您的ContetPages将有不同的图像，您想要从MasterPage触发SetupFeaturedProperty功能？如果是这样，请尝试以下操作：

MasterPage.master

 ...

    <head>

      <asp:ContentPlaceHolder runat="server" id="Headers">

      </asp:ContentPlaceHolder>
      <script language=javascript>
        function mp_onload()
        {
          if(window.body_onload != null)
          window.body_onload();
        }
      </script>
    </head>
    <body onload="mp_onload();">

    ...

如果您的内容页面可能需要onload事件，那么您只需要在需要它的每个页面的Headers内容区域中创建一个名为body_onload的函数。它会自动从MasterPage调用。

Default.aspx的

<asp:Content ID="Content2" ContentPlaceHolderID="Headers" Runat="Server">
  <script language="javascript">
    function body_onload()
    {
      SetupFeaturedProperty(1,['http://www.brightlogic-estateagents.co.uk/MRUS/upload/1076-1.jpg', 'http://www.brightlogic-estateagents.co.uk/MRUS/upload/1076-2.jpg', 'http://www.brightlogic-estateagents.co.uk/MRUS/upload/1076-3.jpg', 'http://www.brightlogic-estateagents.co.uk/MRUS/upload/1076-4.jpg']);SetupFeaturedProperty(2,['http://www.brightlogic-estateagents.co.uk/MRUS/upload/122-1.jpg', 'http://www.brightlogic-estateagents.co.uk/MRUS/upload/122-2.jpg', 'http://www.brightlogic-estateagents.co.uk/MRUS/upload/122-3.jpg', 'http://www.brightlogic-estateagents.co.uk/MRUS/upload/122-4.jpg']);SetupFeaturedProperty(3,['http://www.brightlogic-estateagents.co.uk/MRUS/upload/38-1.jpg', 'http://www.brightlogic-estateagents.co.uk/MRUS/upload/38-2.jpg', 'http://www.brightlogic-estateagents.co.uk/MRUS/upload/38-3.jpg', 'http://www.brightlogic-estateagents.co.uk/MRUS/upload/38-4.jpg']);SetupFeaturedProperty(4,['http://www.brightlogic-estateagents.co.uk/MRUS/upload/918-1.jpg', 'http://www.brightlogic-estateagents.co.uk/MRUS/upload/918-2.jpg', 'http://www.brightlogic-estateagents.co.uk/MRUS/upload/918-3.jpg', 'http://www.brightlogic-estateagents.co.uk/MRUS/upload/918-4.jpg']);SetupFeaturedProperty(5,['http://www.brightlogic-estateagents.co.uk/MRUS/upload/1039-1.jpg', 'http://www.brightlogic-estateagents.co.uk/MRUS/upload/1039-2.jpg', 'http://www.brightlogic-estateagents.co.uk/MRUS/upload/1039-3.jpg', 'http://www.brightlogic-estateagents.co.uk/MRUS/upload/1039-4.jpg']);
    }

编辑：根据您对如何在代码隐藏中启动函数的评论（未经测试）：

Dim allImageUrls As New List(Of String)(New String() {"http://www.brightlogic-estateagents.co.uk/MRUS/upload/1076-1.jpg", "http://www.brightlogic-estateagents.co.uk/MRUS/upload/1076-2.jpg", "http://www.brightlogic-estateagents.co.uk/MRUS/upload/1076-3.jpg", "http://www.brightlogic-estateagents.co.uk/MRUS/upload/1076-4.jpg", "http://www.brightlogic-estateagents.co.uk/MRUS/upload/122-1.jpg", "http://www.brightlogic-estateagents.co.uk/MRUS/upload/122-2.jpg"})
If allImageUrls.Count <> 0 Then
   Dim arrayBuilder As New System.Text.StringBuilder("[")
   For Each imageUrl As String In allImageUrls
       arrayBuilder.Append("'").Append(imageUrl).Append("',")
   Next
   arrayBuilder.Length -= 1 ' remove last comma '
   arrayBuilder.Append("]")

   Dim jsVarImgUrls As String = arrayBuilder.ToString
   Page.ClientScript.RegisterArrayDeclaration("allImageURLs", jsVarImgUrls)
End If

然后，您可以从onload-function中轻松访问该数组，例如：

OnLoad = "SetupFeaturedProperty(1, allImageURLs);"

如何在Master Page load上分配值？
