如何使.net服务器端生成alert/confim消息？

一、服务器端生成alert代码

message ：消息内容

delay ：延迟多长时间之后弹出消息框

FocusControl ：关闭对话框之后焦点所在

AddScript：关闭对话框之后页面处罚的事件

IsUrl：关闭对话框之后转向的页面

PrivateSubalert_client()Subalert_client(ByValmessageAsString,ByValdelayAsInteger,OptionalByValFocusControlAsControl=Nothing,OptionalByValAddScriptAsString=Nothing,OptionalByValIsUrlAsBoolean=False)
DimsAsString,msgAsString,MsgIDAsString
DimsbAsNewSystem.Text.StringBuilder(message)
sb.Replace(vbCrLf," ")
sb.Replace("'","'")
sb.Replace("""","""")

msg=sb.ToString()
MsgID=UniqueMessageID()

s="<scriptlanguage='javascript'>"&vbCrLf
s+="function"&MsgID&"()"&vbCrLf
s+="{"&vbCrLf
s+="alert("""&msg&""");"&vbCrLf
IfNotFocusControlIsNothingThen
s+="window.document.all['"&FocusControl.ClientID.ToString()&"'].focus();"&vbCrLf
IfString.Compare(FocusControl.GetType.ToString,"System.Web.UI.WebControls.LinkButton")<>0Then
s+="window.document.all['"&FocusControl.ClientID.ToString()&"'].select();"&vbCrLf
EndIf
EndIf
IfNotAddScriptIsNothingThen
IfIsUrlThen
s+="window.location='"&AddScript&"';"&vbCrLf
Else
s+=AddScript&vbCrLf
EndIf
EndIf
s+="}"&vbCrLf
s+="//-->"&vbCrLf
Ifdelay=0Then
s+=(MsgID&"();")
Else
s+="window.setTimeout("&MsgID&","&delay&");"&vbCrLf
EndIf

s+="</script>"&vbCrLf

Me.Page.ClientScript.RegisterClientScriptBlock(Me.GetType(),MsgID,s)
EndSub

二、服务器生成confim

message ：消息内容

PostButton ：关闭对话框之后触发的页面postback事件

AddScript：关闭对话框之后页面处罚的事件

ProtectedFunctionconfirm()Functionconfirm(ByValmessageAsString,ByValPostButtonAsButton,OptionalByValAddScriptAsString=Nothing)AsBoolean
DimsAsString,msgAsString,MsgIDAsString
DimsbAsNewSystem.Text.StringBuilder(message)
sb.Replace(vbCrLf," ")
sb.Replace("'","'")
sb.Replace("""","""")

msg=sb.ToString()
MsgID=UniqueMessageID()

s="<scriptlanguage='javascript'>"&vbCrLf
s+="<!--"&vbCrLf
s+="/*ClientAlertFunction"&vbCrLf
s+="CopyRightAPJCorp.com"&vbCrLf
s+="Author:bss(Bianshusen@apjcorp.com)"&vbCrLf
s+="Date:2004-8-24"&vbCrLf
s+="*/"&vbCrLf
s+="function"&MsgID&"()"&vbCrLf
s+="{"&vbCrLf
s+="varb;"&vbCrLf
s+="b=false;"&vbCrLf
s+="b=confirm("""&msg&""");"&vbCrLf
s+="if(b==false)"&vbCrLf
s+="{"&vbCrLf
s+="returnfalse;"&vbCrLf
s+="}"&vbCrLf
s+="else"&vbCrLf
s+="{"&vbCrLf
s+="__doPostBack('"&PostButton.UniqueID&"','');"&vbCrLf
s+="}"&vbCrLf

IfNotAddScriptIsNothingThen
s+=AddScript&vbCrLf
EndIf
s+="}"&vbCrLf
s+="//-->"&vbCrLf


s+="window.setTimeout("&MsgID&",10);"&vbCrLf

s+="</script>"&vbCrLf

'Me.Page.RegisterClientScriptBlock(MsgID,s)

Me.Page.ClientScript.RegisterClientScriptBlock(Me.GetType(),MsgID,s)

ReturnTrue
EndFunction

相关代码：

ProtectedSubalert()Subalert(ByValmessageAsString,ByValFocusControlAsControl,OptionalByValdelayAsInteger=10,OptionalByValAddScriptAsString=Nothing,OptionalByValIsUrlAsBoolean=False)
alert_client(message,delay,FocusControl,AddScript,IsUrl)
EndSub
ProtectedSubalert()Subalert(ByValmessageAsString,OptionalByValdelayAsInteger=10,OptionalByValAddScriptAsString=Nothing,OptionalByValIsUrlAsBoolean=False)
alert_client(message,delay,,AddScript,IsUrl)
EndSub

ProtectedFunctionUniqueMessageID()FunctionUniqueMessageID(OptionalByValidAsInteger=1)AsString
ConstMessageNameAsString="__MessageBox"

IfNotMe.Page.ClientScript.IsClientScriptBlockRegistered(MessageName&id.ToString)Then

ReturnMessageName&id.ToString
Else
ReturnUniqueMessageID(id+1)
EndIf
EndFunction
