How can I count the unique number of phone numbers in a textarea separated with comma, newline or space?

Question

How can I count the unique number of phone numbers in a textarea separated with comma, newline, or space in javascript or jQuery? I have tried this code:

$('#gsmnumbers').on('keyup', function() {
    $('#num-counter').html($('#gsmnumbers').val().split(',').length);
});

would be nice to see a snippet of code, what have you tried so far? — swidmann, Oct 14 '15 at 07:28

You can use a regular expression to split the string by multiple characters:

var count = $('textarea').val().split(/[\n,\s]/).length;

Example fiddle

Note that you may need to sanitise the input if it's user-entered as spaces are commonly used delimiters within a phone number itself, which may lead to an incorrect count.

Once you've got your array you can de-duplicate it, see here: http://stackoverflow.com/questions/9229645/remove-duplicates-from-javascript-array – Rory McCrossan Oct 14 '15 at 08:08

I was exactly searching for similar answer but using someone's fiddle, I just counted for comma, space, colon, semi colon, line breaks, etc., here is the code if someone in future needs it.

jsfiddle

var yay = $('textarea').val().split(/[\ \n\r\;\:\,]+/).length;
alert(yay);

Hope it helps someone.
