Do you have any "parse" commands for jquery?

Question

I get a string like : R$10,00, I wanted to change it to 10.00 to be able to calculate, I tried the code below, but it didn’t work.

   for (let i=0; i<numColunas; i++){
     valor = (colunas[i].textContent).parse("R$", "");
     alert(valor);    
  }

Answer 1

Use regular expression to remove anything other than numbers and virgula

var teste = 'R$10,00';
teste = teste.replace(/[^0-9\,]/g, '');

Change vírgula for ponto and turn the value to float, so you can do calculations with it

teste = teste.replace(',', '.');
teste = parseFloat(teste);

Answer 2

The function below is compact and solves this problem:

function floatvalue($val){
            $val = str_replace(",",".",$val);
            $val = preg_replace('/\.(?=.*\.)/', '', $val);
            return floatval($val);
}

$string = "12,34";
$number = floatvalue($string);

$r = 40 + 7.5 + $number;

echo $r;

Answer 3

You can use the replace with a regex that takes only the numbers and comma.

It is also necessary to exclude all points from the number before replace the comma, because if the number has a thousand separator, will give problem (ex. R$10.000,00 will stay 10.000.00).

valor = parseFloat(("R$10.000,55").replace(/[^\d,]/g, "").replace(',','.'));

In your case, I would:

valor = parseFloat((colunas[i].textContent).replace(/[^\d,]/g, "").replace(',','.'));

Example:

valor = parseFloat(("R$10.000,55").replace(/[^\d,]/g, "").replace(',','.'));
console.log((valor+10.99).toFixed(2));
