I have a textarea with the following list in it 736 4937 587 795 955

1. enter this list in a textarea 736 4937 587 795 955

2.. run my jquery: the output will be this   736, 4937, 587, 795, 955

   var str = $('#ItemList').val();
            str = $('#ItemList').val().replace(/(?:\r\n|\r|\n|\s)/g, ', ');

3.  now the user decide to run my jquery again: the user will get this output for running my query again   736,, 4937,, 587,, 795,, 955

4. How can I fix the jquery to say:

if the data in my textarea already has a comma and space between them then don't do anything.

only separate my list if there is no comma followed by a space between them.

I just don't wont the double comma if the user kept on clicking the button.

Thank you for your help,
