Running a JS from an Asp:button?

Is that possible? I have tried this:

Code:

---

<asp:button id=btnOpen OnClick="Javascript: openNewWindow();" tabIndex=20 Runat="server" CssClass="knap2" Text="Åbn fil"></asp:button>

---

where

Code:

---

<script language=javascript>
                function openNewWindow()
        {
                        var winName = "";
            var winFeatures = "width=520,height=640,top=0,left=0,status";
            var winURL = "http://localhost/Prisberegning2004/udskrift.aspx"
            var w;
            w = window.open(winURL,winName,winFeatures);
        }
</script>

But it doesnt't work

There's a number of ways you could do it, 1 way would be to leave your javascript where it is on your .aspx page and add this line to page_load

VB Code:

btnOpen.Attributes.Add("onclick", "openNewWindow();")

GREAT GREAT, just what I needed!
:D

Maybe you could have an idea of how I can execute a click-event when I hit enter in a textbox.

I have a login consisting of txtUser, txtPassword and btnLogin. When I have entered username and password and hit enter I wish to execute the btnLogin_click.

VB Code:

Page.RegisterHiddenField("__EVENTTARGET", "btnDefault")

where btnDefault is the name of your button.

Hmmm, I've tried that under Page_load, but nothing happens.

Code:

---

Private Sub Page_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
        Page.RegisterHiddenField("__EVENTTARGET", "Login")
    End Sub

---

hmm works for me everytime just tried a page with multiple buttons and it works for each one. when you run the page and view source do you get this line

Code:

---

<input type="hidden" name="__EVENTTARGET" value="Login" />

---

EDIT: There's a problem if you add a JS attribute to the button aswell as the above code, could that be the problem?

Nothing happens when I try to view the source

I have no JS connected to the button "Login"

Please send me the code you're using, then I will try to find out what goes wrong

so it's exactly the same as what i have:

ok so i won't post the vb file, why is .cs a valid extension for uploading but not .vb?

VB Code:

Public Class WebForm1
    Inherits System.Web.UI.Page
 
#Region " Web Form Designer Generated Code "
 
    'This call is required by the Web Form Designer.
    <System.Diagnostics.DebuggerStepThrough()> Private Sub InitializeComponent()
 
    End Sub
    Protected WithEvents RadioButtonList1 As System.Web.UI.WebControls.RadioButtonList
    Protected WithEvents btnClose As System.Web.UI.WebControls.Button
    Protected WithEvents Button2 As System.Web.UI.WebControls.Button
    Protected WithEvents Label1 As System.Web.UI.WebControls.Label
    Protected WithEvents Button3 As System.Web.UI.WebControls.Button
    Protected WithEvents btnDefault As System.Web.UI.WebControls.Button
    Protected WithEvents TextBox1 As System.Web.UI.WebControls.TextBox
    Protected WithEvents btnDefault2 As System.Web.UI.WebControls.Button
 
    'NOTE: The following placeholder declaration is required by the Web Form Designer.
    'Do not delete or move it.
    Private designerPlaceholderDeclaration As System.Object
 
    Private Sub Page_Init(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Init
        'CODEGEN: This method call is required by the Web Form Designer
        'Do not modify it using the code editor.
        InitializeComponent()
    End Sub
 
#End Region
 
    Private Sub Page_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
        'Page.RegisterStartupScript("MyScript", "<script language=javascript>" & _
        '       "function AlertHello() { alert('Hello ASP.NET'); }</script>")
        Page.RegisterClientScriptBlock("MyScript", "<script language=javascript>" & _
               "function AlertHello() { alert('Hello ASP.NET'); }</script>")
        Button2.Attributes.Add("onclick", "AlertHello()")
        Page.RegisterHiddenField("__EVENTTARGET", "btnDefault2")
 
        'btnClose.Attributes.Add("onclick", "window.close();")
        btnClose.Attributes.Add("onclick", "closewin();")
    End Sub
    Private Sub btnClose_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnClose.Click
        Dim a As Int16
        a = 16
    End Sub
 
    Private Sub Button3_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button3.Click
        Dim x, y As Int16
        x = 2
        y = 0
        Dim z As Int16 = x / y
    End Sub
 
    Sub btnDefault_Click(ByVal sender As System.Object, ByVal e As System.EventArgs)
        Dim i As Int16 = 2
    End Sub
 
    Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click
        Dim a As Char = "w"
    End Sub
 
    Private Sub btnDefault2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnDefault2.Click
        Dim i As Int16 = 2
    End Sub
End Class

Hi again, thanks for your code. The code works fine. But when I apply a new textbox (I have two textboxes in my Login app) something strange happens. When I hit enter the event for closing the window is running instead of the btnDefault2-event
:confused:

Yep i've just done the same and got the same results.

I want to sort this out so i'll going to try some things.......
