Question

Using this code, user won’t enter numeric value. In Google Chrome, input box is not taking numeric value but in Firefox it takes. I’m not getting, why it is happening. Any help appreciated.

<input type="text" name="station_name" id="station_name" onKeyPress="return noNumbers(this)" maxlength="45" />

this is my javascript function

<script type="text/javascript" language="javascript">
 function noNumbers(evt)
            {
                var charCode = (evt.which) ? evt.which : event.keyCode;
                if((charCode>=65 && charCode<=90)||(charCode>=97 && charCode<=122)||(charCode==32))
                    return true;
                return false;
            }
</script>

This is because, in Firefox, the event is passed as a parameter to the event handler. event property of the window object is IE only.

function enterHere(e)
{
    e = e || window.event;
    var code = e.keyCode || e.which;
    if(code == 13)
        find();
}
