    Running Javascript and ASP

    I want to run some javascript code and then some ASP.NET code.
    I can do both function seperately by pressing two different objects. But I cannot to then off one object.


    Below I have:

    > An image which when I click runs a javascript function.
    > A button which does the ASP.NET processing.

    I want to run both the javascript and ASP.NET off a single click of the ASP button (btnsub_Click).

    [PHP]
    <%@ Page Language="VB" %>
    <script runat="server">

    Sub btnsub_Click(By Val Sender As Object, ByVal E As EventArgs)

    If Page.IsValid Then
    ' Do Something

    End If
    End Sub
    </script>

    <html>
    <head><script type="text/javascript">
    javafunction() etc.. etc..
    </script>
    </head>

    <a onclick="javafu nction()"><img src="graphic.gi f" /></a>

    <asp:button id="btnsub" text="Submit" onClick="btnsub _Click" runat="server" />
    [/PHP]


    __

    Does anyone know I can add "javafunction() " to the button click code?


    Would appreciate any help.

    Thanks

      Yes you can !!!

      <asp:button id="btnsub" text="Submit" onClick="btnsub _Click; javafunction()" runat="server" />

      decide which function you want to run first and put it first.

          Hi Scripto,

          Thanks for your help!

          I tried putting both actions (javascript and vb button click ) on the click event of the ASP.NET button - like you said.

          Unfortunately I get this error ::::

          [PHP]Compilation Error
          Description: An error occurred during the compilation of a resource
          required to service this request.

          Please review the following specific error details and modify
          your source code appropriately.

          Compiler Error Message: BC30456: 'myjavafunction ' is not a member of 'myfile.aspx'.


          [/PHP]


          Do you have any further suggestions as to what I am doing wrong

          Thanks

              My error - i was obviously thinking classic ASP

              here goes:

              in the Page_Load() function, add this line
              Button1.Attribu tes.Add("onclic k", "myjavafunction ()");

              That will execute before the server side button_Click() function
              you can add as many of these lines as you wish, each with a different myjavafunction( )

              sorry about the mixup.

                  Hello!

                  I have a question to this topic:

                  Is it possible to define the sequense of the functions which i add with:

                  Button.Attribut es.Add("onclick ", "MM_goToURL ()")

                  Because I like to go run through the ASP Code first.

                  Thank you for your help!!

                      The way it is coded now the javascript will run first. If you want the ASP or server side code to run first, then take a look at a function called RegisterClientS criptBlock() This is coded in your Button1_Click() event , but it registers the javascript code for you, so that function would be put at the very end of you server side code.

                      That will work - i use it all the time.

                              here you are:

                              Dim scriptString As String = "<script language=JavaSc ript> function MM_goToURL() {"
                              scriptString += "alert("TESTlll lllllllllllllll llllllllllllll" );}"
                              scriptString += "/"
                              scriptString += "script>"

                              RegisterClientS criptBlock("sta rt", scriptString)

                              End Sub

                              remove the javascript function that you have MM_goToURL it is not needed.
