image.js 提交到aspx页后，aspx页面处理如下，如何通知html页运行结果，以关掉上传窗
public partial class UpLoad : System.Web.UI.Page
{
    protected void Page_Load(object sender, EventArgs e)
    {
        int loop1;
        HttpFileCollection Files;
        Files = Request.Files;
        if(Files != null)
        {
            string[] arr1 = Files.AllKeys;
            for (loop1 = 0; loop1 < arr1.Length; loop1++)
            {
                HttpPostedFile hpostfile = Files[loop1];
                string str = hpostfile.FileName;

                int EndStr = str.LastIndexOf("\\");
                str = str.Substring(EndStr);
                string filepath = Server.MapPath("upload");
                filepath += str;
                hpostfile.SaveAs(filepath);
            }
            string strWidth = Request["imgWidth"];
            string strHeight = Request["imgHeight"];
            string strAlign = Request["Align"];
            Response.Write("Fire in the hole~");
        }
    }
}

暈，自己顶自己，从其他帖子中找到了方法，由于要配合其他XML接口，删除掉了部分功能，仅提供简单图片插入。
感谢einsta，是你的帖子提供了处理方法。
当然更感谢Roddy，你提供了这样一个优秀的功能。

public partial class UpLoad : System.Web.UI.Page
{
    private readonly string _UpLoadFolder = "upload";
    private string _relateFolder;

    protected void Page_Load(object sender, EventArgs e)
    {
            HttpPostedFile UploadFileHandle = Request.Files["imgFile"];
            string strWidth = Request["imgWidth"];
            string strHeight = Request["imgHeight"];
            string id = Request["id"];

            string myUrl = SaveFile(UploadFileHandle);
            ReturnImg(id, myUrl, strWidth, strHeight);
    }

    private string RelateFolder
    {
        get { return _relateFolder; }
        set { _relateFolder = value; }
    }
