Please refer similar discussion:
Key press event is not working in mozilla fire fox[^]
onkeypress() not working[^]
jQuery keypress() event not firing[^]

Have a look on: JavaScript Madness: Keyboard Events[^] for more information.

Solution 2

try this , it works in both:

C#

function isNumericKeyStroke(evt) {
           var returnValue = false;
           var charCode = (window.Event) ? evt.which : evt.keyCode
           if (((charCode >= 48) && (charCode <= 57)) || // All numerics
          (charCode == 8) ||     // Backspace
          (charCode == 13))     // Carriage Return
           {
               returnValue = true;
           }
          return returnValue;
       }

Hi thanx for solution, but my problem is with using master page.
My code as follows

<asp:Content ID="Content1" ContentPlaceHolderID="HeadContent" runat="server">
<script language="javascript" type="text/jscript" >
function isNumericKeyStroke(evt) {
alert("key pressed !");
var returnValue = false;
var returnValue = false;
var charCode = (window.Event) ? evt.which : evt.keyCode
if (((charCode >= 48) && (charCode <= 57)) || // All numerics
(charCode == 8) || // Backspace
(charCode == 13)) // Carriage Return
{
returnValue = true;
}
return returnValue;
</script>

<asp:Content ID="Content2" ContentPlaceHolderID="MainContent" runat="server">
<asp:TextBox runat="server" ID="txtCredit"
Width="80" onkeypress= "return isNumericKeyStroke(event)" onkeydown="return isNumericKeyStroke(event)"/>

It is a known issue and multiple discussions[^] can be found on internet.

FF doesn't use window.event for keypress, but expects the event to be passed as a parameter to the function handling it
Look 'Fang' answer here for similar discussion on how to handle it: window.event.keycode 13 won't work in Firefox[^]

Another link that will help: http://www.ryancooper.com/resources/keycode.asp[^]

Solution 4

sometimes KeyCode does not work with firefox ,use window.event with if condition to get rid of error in Firefox.
such as :

HTML

var charCode = (window.Event) ? evt.which : evt.keyCode
