mga kuya pano po ba or pwede bang tumawag ng javascript function sa loob ng code behind Sub procedure? VB po

 ex.

 Public Sub blahblah ()

...........some vb codes

-----> CALL JAVASCRIPT FUNCTION<---------

...........some vb codes THAT RETRIEVES A VALUE from the JAVASCRIPT FUNCTION is RECENTLY CALLED

...........some vb codes

end sub

------------------------

ex. calling a 'confirmation dialogbox'

two days na ko nag hahanap sa web pero hindi ganung structure yung tinuturo nila...

 salamat po

hi kuya,

    Hinde un pwede tsong. though may ibang paraan para makagpasa ng data sa dalawang code. Isa na dito ung paggamit ng mga hidden fields at pagreregister ng javascript via server scripts. 

There are several ways to add javascript in the codebehind. The most common technique in ASP.NET 1.x is using the RegisterStartupScript and RegisterClientScript property of the page.

This has been deprecated in ASP.NET 2.0 and has since been replaced by the ClientScriptManager

HTH

How come this code works fine........ 

Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load

Dim hiScript As String = "alert(111);"

If Not Page.ClientScript.IsClientScriptBlockRegistered("hi") Then

Page.ClientScript.RegisterClientScriptBlock(Me.GetType, "hi", hiScript, True)

End If

End Sub

And this dont......

Dim hiScript As String = "alert(111);"

If Not Page.ClientScript.IsClientScriptBlockRegistered("hi") Then

Page.ClientScript.RegisterClientScriptBlock(Me.GetType, "hi", hiScript, True)

End If

End Sub

End If

End Sub

Kasi po nireregister mo ung script mo. Pero dapat ung script nasa code behind din. You will just declare it as a string.

hi kuya,

ung pangalawang  code mu nakalagay sa event handler ng linkbutton1.click, mareregister lng cya pag naclick na ung link button. Unlike ung una na nasa page_load event handler.

Nga pla tsong, pdeng malamang kung anu ung gusto mung mangyari sa program? tnx.

wag niu i run sa isang file yan ha....

 bkt kht i click ayaw pa rin lumabas yung alert?

gagawa sana ko ng time-in/time-out na module... ngayon dun sa submit btn... syempre madaming logical validation, kasama na dun yung kung login ba gagawin nya o mag lolog out na kc wala nmn pag pipilian e. 2 textbox lang at isang button ang nandun.

ngayon naisip ko na kung  gusto nya mag time-in, pero actually nag time-in n sya nkalimutan lang nya, iisipin ng system na logout n yun. now to avoid that... gusto ko sana mag prompt ng isang confirmation dialog ng javascript para sa timeout procedure. tapos ang result nun ay gagamitin ng mga susunod na sub procedures kc nde nmn dun matatapos yung mga validations e kahit alam na ng system na mag lologout na tlga yung user.

bsta ang idea....

public sub button () handles CLICK

vb codes for validations na nka class................

then madadaanan yung validation na kung logout procedure n b, now before that meron sanang CONFIRMATION DIALOG ng JAVASCRIPT

vbcodes for some more validations n nka class p din na nag va-vary depending on the value of the CONFIRMATION DIALOG.....

tapos proceed kung timeIN, timeOUT, o CANCEL

end sub

yan sana na gets niu..

hyyyy bt kc naimbento p tong .net na to e , masaya n nga sa classic e

salamat po...

sori wrong post
