一。后台拼字符串动态加载写法

前台调用代码

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

< html xmlns="http://www.w3.org/1999/xhtml" >

< head id="Head1" runat="server">

    <title>视频播放</title>

< /head>

< body>

    <form id="form1" runat="server">

    <div>

    <table>

      <tr>

        <td><div id="video_content" runat="server" style=""></div>     </td>

      </tr>

    </table>

    </div>

    </form>

< /body>

< /html>

后台调用代码

    {
