How to Filter Numbers Of A String
Not really jQuery at all:
number = number.replace(/\D/g, '');
That regular expression, /\D/g
, matches any non-digit. Thus the call to .replace()
replaces all non-digits (all of them, thanks to "g") with the empty string.
edit — if you want an actual *number value, you can use parseInt()
after removing the non-digits from the string:
var number = "number32"; // a string
number = number.replace(/\D/g, ''); // a string of only digits, or the empty string
number = parseInt(number, 10); // now it's a numeric value
If the original string may have no digits at all, you'll get the numeric non-value NaN
from parseInt
in that case, which may be as good as anything.
