  • 0

I’m trying to write a regex word count, but most of the examples I’ve found only cover a portion of the following situations:

  1. hello,there = should be 2 words (note there is no space after the
    comma)
  2. hello , there = should be 2 words (note the space before and
    after the comma)
  3. $10,000 = should be 1 word
  4. hello there ? = should be 2 words (note the space before the
    question mark)
  5. hello-there = should be 2 words
  6. http://www.google.com = should be 1 word
  7. http://www.google.com/analytics = should be 1 word

I’m currently using the following code in jquery

var total_words = $.trim($("#mytextbox").value).split(/[\s\-\.\\\/\?\!]+/).length

but it only covers situations #3 and #5.

Covering URLs is less of a priority to me.

Any help would be appreciated!

    The following RegEx will work for all your examples:

    var total_words = /(\b(https?|ftp):\/\/([\-A-Z0-9.]+)(\/[\-A-Z0-9+&@#\/%=~_|!:,.;]*)?(\?[A-Z0-9+&@‌​#\/%=~_|!:,.;]*)?)|[+-]?[0-9]{1,3}(?:,?[0-9]{3})*(?:\.[0-9]{2})?|(&)|('\w+)|(\w+'‌​\w+)|(\w+')|(\w+)/gi

    This RegEx was converted from JSoft to JavaScript:

    (\b((?#protocol)https?|ftp)://((?#domain)[-A-Z0-9.]+)((?#file)/[-A-Z0-9+&@#/%=~_|!:,.;]*)?((?#parameters)\?[A-Z0-9+&@#/%=~_|!:,.;]*)?)|[+-]?[0-9]{1,3}(?:,?[0-9]{3})*(?:\.[0-9]{2})?|\w+

    This first section defines any url type item:

    (\b((?#protocol)https?|ftp)://((?#domain)[-A-Z0-9.]+)((?#file)/[-A-Z0-9+&@#/%=~_|!:,.;]*)?((?#parameters)\?[A-Z0-9+&@#/%=~_|!:,.;]*)?)

    The section section is for currency with or without decimals:

    [+-]?[0-9]{1,3}(?:,?[0-9]{3})*(?:\.[0-9]{2})?

    Finally the third section matches words:

    \w+
