Javascript remove square brackets from a string.

I am working with a string that may contain 1+ combinations of open "[" and close "]" brackets.
I need to remove those brackets and any remaining spaces from the string.

For example, I may receive this:

[br549   ] [001] [fkrig  009] [      ] [ 01 ]

I need to transform it to the following in order to work with it:


How can I do this using Javascript, jQuery and/or regex?

Hello JeffDrummond,

Try (regex) :

var mynewstring = "[br549   ] [001] [fkrig  009] [      ] [ 01 ] ".replace(/\s|\[|\]/g,"");

Open in new window

Work fine :

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "">
<html xmlns="">
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>Untitled Document</title>
var mynewstring = "[br549   ] [001] [fkrig  009] [      ] [ 01 ] ".replace(/\s|\[|\]/g,"");

Open in new window

assuming your string is in variable str, try:

str = str.replace(/((\[\s*)|(\s*\]))/g,"")

Thanks leakm971 and hielo:

Your solutions are very helpful for the first part of this task.

The string I am working with is a mask.
First I needed to remove the "[ ]" characters and check what remained to validate
that a value was entered.  Your code does that.

Second, I need to remove the "[ ]" characters and preserve the spacing between
any entered characters.  I didn't mention it before, but spaces in the mask have a "."

So using my first example, I may receive this:
[br549...] [001] [.fkrig..009] [.....] [.01.]

And I need to save this:

br549   001 fkrig  009      01

as a string.

Can this be done?

on my example, just get rid of the \s*:

str = str.replace(/((\[)|(\]))/g,"")
