How to remove suffix from string?

How can I remove the following suffix:

  1. px
  2. %
  3. em

from some string if it contains that suffix ?
Like enter I get string which can be measure of width of div and that can ends with 'px', '%', 'em' and can also be without, so I need to remove suffix if it exists.

var s = "34em";
parseInt(s, 10); // returns 34

this works for em, px, %, pt... and any other suffix even if it has a space before.

Use parseFloat() instead if you have non-integer values

var s = "81.56%";
parseFloat(s); // returns 81.56

You can use a regular expression to get a string with only the digits:

var s = input.replace(/\D+/g, '');

You can parse the string as a number, that will ignore the non-numeric characters at the end:

var n = parseInt(input, 10);
