This will remove all unnecessary commas in the text and update the text value:

$('.dyn-').text($('.dyn-').text().replace(/^,*|,(?=,)|,$/g, ''));

The regex is in three parts, seperated by |:

first part catches all the commas in the beginning of the string, since they come before a word, they are all unnecessary,
second part catches all commas followed by a comma, so only the last of the repeating commas will stay,
and third part catches a comma that is at the very end of the string, which is unnecessary.

i think it would be easier to get to the source that is causing you this trouble instead of trying it backwards.. their is a solution but why not trying to remove it from the beginning?

any chance to let us see the code? maybe we could come up with the problem from the source.
