javascript regex brackets match won't work, it changes the regex pattern

Question

I'm trying to use this regex pattern to match this value [1] When I use this regex:

new RegExp("\\["+row+"\\]/g")

it returns me this:

/\[1\]\/g/

instead of this:

/\[1\]/g

I have tried many things but nothing works apparently.

Some help would be appreciated.

pass the g flag as the 2nd argument to the ctor. – Alex K. May 24 '17 at 10:30 — Alex K., May 24 '17 at 10:30

Don't put the regex delimiter when you're using the constructor:

new RegExp("\\["+row+"\\]", 'g')
