How to slice/extract 8 characters after second comma in a string ? Note: Dynamic string length, and comma position is not static

Question

I would like to split/extract the 8 characters which are always between the second and third comma in a string. Earlier, I split the 8 characters from 24 to 31 position in a string, but the position can vary based on the position of the commas.

Example of string:

var mystr = “1xxxxxxxx,2xxxxxxxxxxxxxx,9xxxxxxx,0xxxxxxx,XX,Rxxxxxxx,”;.

var neededcode = Code.slice(23,31);

Output should be “9xxxxxxx”.

@CertainPerformance is regex necessary here? You can just use the built-in split function to find it. — Jack Moody, Jan 11 '19 at 07:57
@JackMoody I agree. An alternative is to also look up occurrences of commas and calculate the index range to extract. — VLAZ, Jan 11 '19 at 08:00
@JackMoody Oh, you're right, I missed the fact that the desired match will always be between two commas. https://jsfiddle.net/o5hfy4b6/ — CertainPerformance, Jan 11 '19 at 08:10

The Javascript split() function seems to be what you are after. This function allows you to create an array. In your example, this would return ["1xxxxxxxx","2xxxxxxxxxxxxxx","9xxxxxxx","0xxxxxxx","XX","Rxxxxxxx"]. Then, to find the value after the second comma and before the third comma, you would just take the third element of the array using mystr.split(",")[2].

Code

var mystr = "1xxxxxxxx,2xxxxxxxxxxxxxx,9xxxxxxx,0xxxxxxx,XX,Rxxxxxxx,";
    
var mysplit = mystr.split(",")[2];
console.log(mysplit);

Output

9xxxxxxx
