javascript - How to replace text when the string exactly matches the search -


i using following code remove words chat text:

for(var =0; <db.banned_words.length ;i++){     cleaned_msg = cleaned_msg.replace(new regexp(db.banned_words[i], 'g'), ''); }

the problem if cleaned_msg has 1 of banned words, not remove cleaned_msg.

ex; cleaned_msg = 'duck' ; if duck 1 of banned words, then, after replace, cleaned_msg should '', 'duck'.

if cleaned_message has other spaces or characters, works fine. ex; duckie returns 'ie'; ' duck' returns ' '.

your approach should working issue lies somewhere else. may suggest different approach?

var banned_words = ['duck', 'cool', 'test'],     banned_words_rx = new regexp('\\b(' + banned_words.join('|') + ')\\b', 'gi');  'this duck cool, cool used test thing'.replace(banned_words_rx, '');
