Question

I am looking to create a reg ex in JS that obtains 2 values from a string:

The string is always in the following format value1[value2].

what is the best way to do this?

Answer 1

var str = "value1[value2]";
var match = str.match(/([^\[]*)\[([^\]]*)\]/);
// match = ["value1[value2]", "value1", "value2"]

Explanation

• ([^\[]*): capture everything until the [ character.
• \[: the [ character.
• ([^\]]*): capture everything until the ] character.
• \]: the ] character.
