I found some code online (stackoverflow https://stackoverflow.com/a/5774234/150062) that does exactly what I need. But I can't seem to get it running. I get an error "'/(\\d+)\\s*(second|min|minute|hour)/g' is not a function (evaluating 'regex(s)')";

var timespanMillis = (function() {
  var tMillis = {
    second: 1000,
    min: 60 * 1000,
    minute: 60 * 1000,
    hour: 60 * 60 * 1000 // etc.
  };
  return function(s) {
    var regex = /(\d+)\s*(second|min|minute|hour)/g, ms=0, m, x;
    while (m = regex(s)) {
      x = Number(m[1]) * (tMillis[m[2]]||0);
      ms += x;
    }
    return x ? ms : NaN;
  };
})();

I've never heard of this regex() function either? Is it suppose to be something else?

    `regex` is a [RegExp object](https://developer.mozilla.org/en-US/docs/JavaScript/Reference/Global_Objects/RegExp), not a function. The author of that code made a mistake. – Snowball Aug 21 '12 at 18:48

This used to be possible, you can replace the call with exec for exact same mechanism:

m = regex.exec(s)

See http://whereswalden.com/2011/03/06/javascript-change-in-firefox-5-not-4-and-in-other-browsers-regular-expressions-cant-be-called-like-functions/

i think 

regex.match(value)//or regx.exec(value)

is function you are looking for

regex is a RegExp object, not a function. here listing of method and function of Regular Expressions methods and usage

if match is not working than tryout .test() method like this 

var match = /sample/.test("Sample text")

or 

var match = /s(amp)le/i.exec("Sample text")

  • Replacing it with that doesn't seem to work... Apparently that code doesn't work at all, nor is it intended to. Apparently it's demo code. – Steven Aug 21 '12 at 18:51
  • @Steven - than try out .test() method of the object..check the method on given link of answer – Pranay Rana Aug 21 '12 at 18:52
