Remove 'R$' before converting to Double

Question

I have a list of products in a table, and in order to make the interface more friendly, in the column 'price' I awarded the 'R$' next to the value. Now I need to capture this value to do a mathematical operation and need to convert to float:

 //captura o valor da linha na table
var linha = $(this).parent('td').parent('tr');
// deve converter o valor para Float
var valor = parseFloat(linha.find('td:eq(1)').text());

Using Jquery, how do I remove the 'R$' characters and convert the value to Float?

Answer 1

Tries that answer:

var linha = $(this).parent('td').parent('tr');
var valor = Number(linha.find('td:eq(1)').text().replace(/[^0-9\.-]+/g,""));
