So I have this:
var str = A123B234C456;
I need to split it into comma separated chunks to return something like this:
I thought regex would be best for this but i keep getting stuck, essentially I tried to do a string replace but you cannot use regex in the second argument
I would love to keep it simple and clean and do something like this but it does not work:
str = str.replace(/[\d]+/, ","+/[\d]+/);
but in the real world that would be too simple.
Any thoughts? Thanks in advance!
It may be more sensible to match the characters and then join them:
str = str.match(/(\d+|[^\d]+)/g).join(',');
But don't omit the quotes when you define the string:
var str = 'A123B234C456';
Hi You can do it by replace using regex for example
var str = "A123B234C456"; str = str.replace(/([a-bA-B])/g, '$1,');
now str value will be 'A,123,B234,C456';
String split method can be called with a regexp. If the regexp has a capture group, the separator will be kept in the resulting array. So here you go :
let c = "A123B234C456"; let stringsAndNumbers = c.split(/(\d+)/); // ["A","123","B","234","C","456",""]
Since your example ends with numbers, the last element will be empty. Remove empty array elements :
let stringsAndNumbers = c.split(/(\d+)/).filter(el => el != ""); // ["A","123","B","234","C","456"]
Then join :
let stringsAndNumbers = c.split(/(\d+)/).filter(el => el != "").join(","); // "A,123,B,234,C,456"
