I'm working on a web page and trying this script but it is not working (although it is working fine in IE). The code is given below:

My function is:

function validateNumber()
        {
            var x=window.event.keyCode;
            //alert(x);
            if(!(x>=48 && x<=57))
                {
                    alert("Please type a number between 0 and 9 !!");
                }
        }


I'm using it like:

<input type="text" name="cust_age" value=0 size="15" onkeypress="return validateNumber()" style="font-size: 16pt" />

Please let me know how to resolve this problem.

Firefox doesn't use a global window event. On Firefox you need to pass the event to the function.

I think that this should work (I'm not an expert):

<input type="text" name="cust_age" value=0 size="15" onkeypress="return validateNumber(event)" style="font-size: 16pt" />

function validateNumber(event)
        {
            var x=window.event? window.event.keyCode : event;
            //alert(x);
            if(!(x>=48 && x<=57))
                {
                    alert("Please type a number between 0 and 9 !!");
                }
        }
