Why Javascript is not working properly?
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 !!");
}
}
