Splitting a string between two reoccurring characters

Question

I have dynamic values in a variables, each separated with [ and ] eg

var data="[Continuing] [Returning] "; or
var data="[ACCT_BBA] "; or
var data="[12001] [12009] [21077] [13880] ";
var data="[13880] ";

Is there a way to use the split function to extract the values between the [ and the ] from above?

var arr= data.split("<what goes here?>");

eg on the last example to retrieve: 12001, 12009, 21077, 13880

Answer 1

data.slice(1, -2).split("] [")

should do the job, or if your start and end are uncertain maybe

data.replace(/^\s*\[|\]\s*$/g, "").split("] [")

Alternatively, if you need something more complex, the choice is usually .match with a global regex, or building your own parser if you need to handle arbitrarily nested structures.

Answer 2

Use

data.split('] [').map(function (item) { return item.replace("]", "").replace("[", "")})

like this:

  //var data="[Continuing] [Returning]"; // var data="[ACCT_BBA]"; var data="[12001] [12009] [21077] [13880]"; var res = data.split('] [').map(function (item) { return item.replace("]", "").replace("[", "")}) console.log(res) 

Answer 3

What about data.match(/\\[(\\w+)\\]/g).map(e => e.slice(1, -1))

And you can replace \\w with the scope of character, like [a-zA-Z0-9_]

Answer 4

Yes if you do:

var data="[12001] [12009] [21077] [13880]";

var arr = data.split(" ");

for(let i = 0; i < arr.length; i++){
    arr[i] = arr[i].replace('[','');
    arr[i] = arr[i].replace(']','');
}
console.log(arr);

just an example, very basic one.
