jQuery / Javascript replace multiple occurences not working -

-

i'm trying replace multiple occurrences of string , nothing seems working me. in browser or when testing online. going wrong?

str = '[{name}] happy today data-name="[{name}]" won match today. [{name}] made 100 runs.';  str = str.replace('/[{name}]/gi','john');  console.log(str);

http://jsfiddle.net/sxtd4/

i got example here, , wont work.

you must not quote regexes, correct notation be:

str = str.replace(/\[{name}\]/gi,'john');

also, have escape [], because otherwise content inside treated character class.

updating fiddle accordingly makes work.

there 2 ways declaring regexes:

// literal notation - preferred option var re = /regex here/; // via constructor var re = new regexp('regex here');
