Question

It’s possible I’m just misusing .filter() here, but I’ve been trying to extract a particular piece of text from javascript option boxes without much success.

In short, each of my option boxes has a bunch of info, then, in brackets, ([x] items left in stock).

I’d like to extract that [x], but I can’t seem to get any sort of regular expression filtering working in jQuery – or, perhaps, I’m doing it wrong.

In short, if anyone could complete the below, I’d be very appreciative:

$('.productSelect').change(function() {
  selectedItem = $(this + 'option:selected').text();

  # Now grab the integer "x" inside the ([x] items left in stock) part of the text
  [ your code here]
});

Any help very appreciated.

Answer 1

Something along these lines:

$('.productSelect').change(function() {
  selectedItem = $(this + 'option:selected').text();

  # Now grab the integer "x" inside the ([x] items left in stock) part of the text
  var n = selectedItem.match(/(\()(\d+)(\))/)[2];
});

Of course, this expression depends on the fact that your data is formatted as (number) string
