Making a number only input field and strip out other characters? 1

[bazil2]

(Elementary user)

The following is an abridged input filter that removes any character that is not a-z which I believe is defined by the value 'lowercaseLetters'

To adapt this filter to make it numbers only, can anyone tell me what the value should be?

Best regards

------------------------------------
function only_a_to_z(theField, val, v, args)
{
// normal textfield. Do the filter.
s = stripCharsNotInBag(val, lowercaseLetters);

// if we have supplied a pointer to another field, we put the data there...
if (args && args.length==1) {
theField.form[args[0]].value = s;
} else {
theField.value = s;
}

return true;

How would we know? stripCharsNotInBag is not a JS function. It appears to be a custom function. So only you know what it does.

Judging by its name though, I would change lowercaseLetters, to a string containing only numbers.

"1234567890"

Beyond that there's now way to know what its expecting.
