javascript - Why my Regex let me write "," (Comma)? -

i have javascript regex function code above:

function acceptdigits(objtextbox) {     var exp = /[^\d{1,3}]/g;     objtextbox.value = objtextbox.value.replace(exp, ''); };

always write special character function remove character example:

i write 45656654@ , function clean "@" 45656654.

my problem

the problem when write "," (comma) function not work, try ".-()/&%$#" , function work.

any catch , remove comma?

/[^\d{1,3}]/g

means "a single character neither digit, curly brace nor comma".

you meant

/\d{1,3}/g

but actually, if want use regex replace non-digits, use

/\d+/g
