/[{}[\]^]+/g,

The above Regex expression is copied from a javascript function and need to eliminate the global search for open and close square braces. [] and leave the other parameters. I can only recognize the close brace but not the open.

/[{}[\]^]+/g,

In reverse, I need a Regex expression in which ONLY the open and close square braces. [] are searched for regardless of their position.

Thanks in advance for any help.

I don't entirely understand what you want.

To search for (curly) braces use
[{}]
that is, either a { or a } .

To search for (square) brackets use
[[\]]
that is, either a [ or a (quoted) ] ,
or
[][]
that is, either a ] (which doesn't need to be quoted here as it's the first character in the character set) or a [ .

Edit: Corrected typo.

Much thanks for the clarification. I didn't know which square brace did what, as well as what the caret ^ and the plus + sign meant in the context, as well as the first forward slash, (I did know that /g meant global). I meant to separate the expressions where one is to be for the square braces and the other is for the curly braces. Now it's all clear to me. Thanks again.
