Javascript replace with reference to matched group

Question

I have a string  such as hello  there   I d like to replace the two underscores with  lt div gt  and  lt  div gt  respectively  using JavaScript  The output would  therefore  look like hello  lt div gt there lt  div gt   The string might contain multiple pairs of underscores   What I am looking for is a way to either run a function on each match  the way Ruby does it    hello  there   gsub             m    lt div gt     m 1  -2      lt  div gt       Or be able to reference a matched group  again the way it can be done in ruby    hello  there   gsub              lt div gt   1 lt  div gt      Any ideas or suggestions

quot hello  there  quot  replace            function a  b       return   lt div gt     b     lt  div gt        Oh  or you could also   quot hello  there  quot  replace             quot  lt div gt  1 lt  div gt  quot    EDIT by Liran H  For six other people including myself   1 did not work  whereas  1 did
