I have this string.

Code: mrkk-918278 ,Title: Blouse-02 ,Price: R$ 60,50 ,Qty: 1 ,Code: mrkk-918277 ,Title: Blouse long sleeve ,Price: R$ 50,50 ,Qty: 1 ,Code: mrkk-918279 ,Title: Blouse-03 ,Price: R$ 70,25 ,Qty: 1 ,Code: mrkk-918280 ,Title: Blouse-04 ,Price: R$ 100,25 ,Qty: 2 Total: R$ 381.75

RESULT

Code: mrkk-918278 Title: Blouse-02 Price: R$ 6050 Qty: 1 Code: mrkk-918277 Title: Long Sleeve Blouse Price: R$ 5050 Qty: 1 Code: mrkk-918279 Title: Blouse-03 Price: R$ 7025 Qty: 1 Code: mrkk-918280 Title: Blouse-04 Price: R$ 10025 Qty: 2 Total: R$ 38175

novoArray = novoArray.toString()**.replace(/,/g, "")

I managed to do so, but it also removes the commas from the values. I would like you to take only from the texts.

Answer 1

novoArray = novoArray.toString().replace(/,(?!\d)/g, "").

Answer 2

If the commas you want to delete always have a space before, just include the space in the regex:

let texto = 'Cód: mrkk-918278 ,Título: Blusa-02 ,Preço: R$ 60,50 ,Qtd: 1 ,Cód: mrkk-918277 ,Título: Blusa manga longa ,Preço: R$ 50,50 ,Qtd: 1 ,Cód: mrkk-918279 ,Título: Blusa-03 ,Preço: R$ 70,25 ,Qtd: 1 ,Cód: mrkk-918280 ,Título: Blusa-04 ,Preço: R$ 100,25 ,Qtd: 2 Total: R$ 381,75';

texto = texto.replace(/ ,/g, ' ');
console.log(texto);

I mean, I change , (a space followed by a comma) for ' ' (only one space). If you have more than one space, you could even use /\s+,/g, so one or more spaces followed by comma are exchanged for a single space. Adapt to your case.

But if you have an array (guess, because the variable is called novoArray), it makes no sense to turn it into string with toString() and then remove the commas. It’s an unnecessary turn because toString returns the elements of the semicolon-separated array, so instead of adding this comma and then removing it, it would be better to join the elements in another way.

An alternative is to use join to join all array elements into a single string, and you choose the text that goes between the elements. In the example below, I chose a space:

let novoArray = ['Cód: mrkk-918278', 'Título: Blusa-02', 'Preço: R$ 60,50',
                 'Qtd: 1', 'Cód: mrkk-918277', 'Título: Blusa manga longa', 'Preço: R$ 50,50',
                 'Qtd: 1', 'Cód: mrkk-918279', 'Título: Blusa-03', 'Preço: R$ 70,25',
                 'Qtd: 1', 'Cód: mrkk-918280', 'Título: Blusa-04', 'Preço: R$ 100,25',
                 'Qtd: 2 Total: R$ 381,75'];

// junta os elementos do array, separando-os por um espaço
console.log(novoArray.join(' '));

Thus you avoid all this unnecessary turn of adding the commas and then using a regex to remove them. With join you choose the text that goes between the elements and you won’t even need the regex.
