Answer 1

Seemd what you want is [\\d+], use exec like this,

var myRe = /\[(\d+)\]/gi;

var myArray, numbers = [];

while ((myArray = myRe.exec(string)) !== null) {
    numbers.push(myArray[1]);
}

Answer 2

You can do:

string = "[Account0].&[1]+[Account1].&[2]+[Account2].&[3]+[Account3].&[4]";
repl = string.replace(/.*?\[(\d+)\][^\[]*/g, function($0, $1) { return $1 });
//=> "1234"

Answer 3

I guess the simplest solution in this case would be:

\[(\d+)\]

simply saying that you only want the digits enclosed by brackets.
