共享兩個做項目最常用功能操作的封裝類

一． 顯示消息對話框類

??? 做項目時總免不了要彈出對話框，或提示用戶，或做用戶確認。像WinForm下的MessageBox一樣很方便，但web下是不是也可以實現呢，答案是肯定的，我簡單總結了一下并封裝到類，在項目里像WinForm的MessageBox那樣直接調用就可以，也可以把它編譯成dll作為組件直接調用，并且它也沒有彈出對話框時的大白屏現象：）。

???? /// <summary>

???? /// 顯示消息提示對話框。

???? /// 李天平

???? /// 2005.10.1

???? /// </summary>

???? public class MessageBox

???? {???????

???????? private? MessageBox()

???????? {????????????

???????? }

???????? /// <summary>

???????? /// 顯示消息提示對話框

???????? /// </summary>

???????? /// <param name="page">當前頁面指針，一般為this</param>

???????? /// <param name="msg">提示信息</param>

???????? public static void? Show(System.Web.UI.Page page,string msg)

???????? {

???? ???????? page.RegisterStartupScript("message","<script language='javascript' defer>alert('"+msg.ToString()+"');</script>");

???????? }

???????? /// <summary>

???????? /// 控件點擊消息確認提示框

???????? /// </summary>

???????? /// <param name="page">當前頁面指針，一般為this</param>

???????? /// <param name="msg">提示信息</param>

???????? public static void? ShowConfirm(System.Web.UI.WebControls.WebControl Control,string msg)

???????? {

????????????? //Control.Attributes.Add("onClick","if (!window.confirm('"+msg+"')){return false;}");

????????????? Control.Attributes.Add("onclick", "return confirm('" + msg + "');") ;

???????? }

???????? /// <summary>

???????? /// 顯示消息提示對話框，并進行頁面跳轉

???????? /// </summary>

???????? /// <param name="page">當前頁面指針，一般為this</param>

???????? /// <param name="msg">提示信息</param>

???????? /// <param name="url">跳轉的目標URL</param>

???????? public static void ShowAndRedirect(System.Web.UI.Page page,string msg,string url)

???????? {

????????????? StringBuilder Builder=new StringBuilder();

????????????? Builder.Append("<script language='javascript' defer>");

????????????? Builder.AppendFormat("alert('{0}');",msg);

????????????? Builder.AppendFormat("top.location.href='{0}'",url);

????????????? Builder.Append("</script>");

????????????? page.RegisterStartupScript("message",Builder.ToString());

?

???????? }

???????? /// <summary>

???????? /// 輸出自定義腳本信息

???????? /// </summary>

???????? /// <param name="page">當前頁面指針，一般為this</param>

???????? /// <param name="script">輸出腳本</param>

???????? public static void ResponseScript(System.Web.UI.Page page,string script)

???????? {

????????????? page.RegisterStartupScript("message","<script language='javascript' defer>"+script+"</script>");

???????? }

???? }

二．頁面數據驗證類

做項目，特別做MIS，更避免不了有用戶輸入數據需要做有效性驗證，這里我總結封裝了一個頁面數據校驗的工具類，用起來也是很方便。

???? /// <summary>

???? /// 頁面數據校驗類

???? /// 李天平

???? /// 2004.8

???? /// </summary>

???? public class PageValidate

???? {

???????? private static Regex RegNumber = new Regex("^[0-9]+$");

???????? private static Regex RegNumberSign = new Regex("^[+-]?[0-9]+$");

???????? private static Regex RegDecimal = new Regex("^[0-9]+[.]?[0-9]+$");

???????? private static Regex RegDecimalSign = new Regex("^[+-]?[0-9]+[.]?[0-9]+$"); //等價于^[+-]?\d+[.]?\d+$

???????? private static Regex RegEmail = new Regex("^[\\w-]+@[\\w-]+\\.(com|net|org|edu|mil|tv|biz|info)$");//w 英文字母或數字的字符串，和 [a-zA-Z0-9] 語法一樣

???????? private static Regex RegCHZN = new Regex("[\u4e00-\u9fa5]");

?

???????? public PageValidate()

???????? {

???????? }

???????? #region 數字字符串檢查??????????????

???????? /// <returns>返回Request查詢字符串</returns>

???????? public static string FetchInputDigit(HttpRequest req, string inputKey, int maxLen)

???????? {

????????????? string retVal = string.Empty;
