项目最常用功能操作的封装类

public class MessageBox

{

private MessageBox()

}

/// <summary>

/// <param name="page">当前页面指针，一般为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>");

}

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>

/// <param name="page">当前页面指针，一般为this</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>

/// 输出自定义脚本信息

/// </summary>

/// <param name="page">当前页面指针，一般为this</param>

/// <param name="script">输出脚本</param>

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

{

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

}

}

二．页面数据验证类

做项目，特别做MIS，更避免不了有用户输入数据需要做有效性验证，这里我总结封装了一个页面数据校验的工具类，用起来也是很方便。

/// <summary>

/// 页面数据校验类

/// 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]+$"); //等价于^[+-]?\d+[.]?\d+$

private static Regex RegEmail = new Regex("^[\\w-]+@[\\w-]+\\.(com|net|org|edu|mil|tv|biz|info)$");//w 英文字母或数字的字符串，和 [a-zA-Z0-9] 语法一样

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

public PageValidate()

{

}
