String Validation 1

[UncleHuckleberry]

I'm new to javascript and i'm trying to create a validation function that will check if the string input is correct. The string should only be numeric values seperated by commas e.g. 12345,23456,34567

can someone please suggest the best way to approach this.

Thanks.

hi
you can use regexp,
or you can scan the string character by character (a `for' loop) and check if it is digit or comma.

here is the regexp, solution:

<SCRIPT>
function is_valid_input(str)
{
    return !(/[^\d,]/.test(str.toString()));
}

alert("12,34" + ' '+ is_valid_input("12,34"));
alert(123 + ' '+is_valid_input(123));
alert("12 34" + ' '+is_valid_input("12 34"));
</SCRIPT>

Do you want to allow whole numbers only? What about negative numbers?
