Can you help me with expression for array: ["232","2323","233"]
I try this: /^\[("\d{1,7}")|(,"\d{1,7}")\]$/
But this expression is not working properly.
I use ruby(rails).

This would validate the array structure well, blocking an entry like [,"123"]

^\[(("\d{1,7}")(,"\d{1,7}")*)?\]$

You may try this ( though it may allow leading ,):

^\[(,?"\d{1,7}")*]$

Why a , before the opening " and after the closing "?
@NaveedS - Unintentionally added. My description was right, but forgot to remove one of the ,
Note this may capture an empty array as well.
@YamMarcovic empty array is allowed I think. @manojlds I suggest a correction ^\[(("\d{1,7}")(,"\d{1,7}")*)?\]$ as it validates the array well. My suggestion for the edit was rejected.
@NaveedS And perhaps even more functional. :) Was just stating a fact to be aware of.

Try this: /^\[("\d{1,7}")(, ?"\d{1,7}")*\]$/
