How to remove square brackets in string using regex?

Question

['abc','xyz'] – this string I want turn into abc,xyz using regex in javascript. I want to replace both open close square bracket & single quote with empty string ie "".

Answer 1

Use this regular expression to match square brackets or single quotes:

/[\[\]']+/g

Replace with the empty string.

"['abc','xyz']".replace(/[\[\]']+/g,'')

Answer 2

str.replace(/[[\]]/g,'')

Answer 3

You probably don't even need string substitution for that. If your original string is JSON, try:

js> a="['abc','xyz']"
['abc','xyz']
js> eval(a).join(",")
abc,xyz

Be careful with eval, of course.
