how to start sub from javascript?

B

Bob

Hi,

The user must enter a name into a text input control. Then i want to give
him the choice between clicking on the button with the mouse or pushing the
ENTER key of the keyboard.

This works when clicking on the button. My problem is that i don't know how
to start the sub 'pseudoserver' when pressing the ENTER key.

Here the code:

the aspx file:
------------
<input id="pseudo" type="text" onkeypress="pseudoclient(event)" />
<br />
<asp:Button ID="pseudoSubmit" runat="server" OnClick="pseudoserver" />

<script type="text/javascript">
function pseudoclient(touche)
{
var codetouche
touche=event
codetouche=touche.keyCode
if(codetouche == 13)
{
????
}
}
</script>

code-behind:
------------
Sub pseudoserver(ByVal sender As Object, ByVal e As System.EventArgs)
....
End sub

Thanks
Bob

The Enter key will activate the default button on the form.
Normally, this is the first button on the form.

You can set another button as the default by setting the form's
DefaultButton property:

<form runat="server" DefaultButton="pseudoSubmit" >

Thanks, but unfortunately, this page is a content page linked to a
masterpage. And there is no <form> in it.

Hi, Bob

I think you can do it through client script.

---- BEGIN CODE ----
<script type='text/javascript'>
function TextBox_onKeyPress(e, obj)
{
e = e ? e : window.event;
if (e.keyCode != 13)
return;

var oForm = obj;
while (oForm && oForm.tagName != "FORM")
oForm = oForm.parentNode;

if (oForm)
oForm.submit();
}
</script>
....
<input type='text' onkeypress='TextBox_onKeyPress(event, this)' />
---- END CODE ----

sorry, my code is in c#

in the code behind file:
txtControl.Attributes.Add("onkeydown", "pseudoclient");

in js:

function pseudoclient(touche)
{
var codetouche
touche=event
codetouche=touche.keyCode
if(codetouche == 13)
{
document.getElementById("<%=this.pseudoSubmit.ClientID
%>").click();
}
}


may it help :)

Thanks for the vb version..
I did it, but there must still be a problem: i have no error of any kind,
but when pushing on ENTER, nothing happens. Clicking on the button still
works.
Here my actual code:

aspx:
----
<asp:TextBox id="pseudo" runat="server"></asp:TextBox>
<asp:Button ID="pseudoSubmit" runat="server" />

<script type="text/javascript">
function pseudoclient(touche)
{
var codetouche
touche=event
codetouche=touche.keyCode
if(codetouche == 13)
{
document.getElementById("<%=pseudoSubmit.ClientID%>").click();
}
}
</script>

and in code-behind:
-------------------
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs)
Handles Me.Load
pseudo.Attributes.Add("onkeydown", "pseudoclient")
End Sub

Although JScript docs say that you can use CRLF as command separators,
it's never a good practice because it might let to some errors.

Try to change the code and tell me what happened:

---- BEGIN CODE ----
function pseudoclient(touche)
{
touche = touche ? touche : window.event;
if (touche.keyCode == 13)
document.getElementById("ctl00_main_pseudoSubmit").click();
}
---- END CODE ----

The point with the compairson in the first line is just to help it
work better with FF.
