I already know how to separate the numbers of three in three, backwards, with regular expression in JavaScript .
But I would like to know if there is a simpler solution in JavaScript, and without the use of regular expression.
For example:
1000; // 1.000
10000; // 10.000
10000000; // 10.000.000
How could I do this?
toLocaleString() does this.
function separarDeTresEmTres(numero) {
return numero.toLocaleString();
}
console.log(separarDeTresEmTres(1000));
console.log(separarDeTresEmTres(1000000));
console.log(separarDeTresEmTres(10000000));In the "nail", I created this function that converts the number to String to be able to traverse the elements, and then use #
var n1 = 1000; // 1.000
var n2 = 10000; // 10.000
var n3 = 100000; // 100.000
var n4 = 1000000; // 1.000.000
var n5 = 10000000; // 10.000.000
function formatarTresEmTres(n) {
n = n.toString();
var nFormatado = '';
for (var i = n.length; i > 0; i = i - 3) {
nFormatado += '.' + n.substring(i - 3, i);
};
return nFormatado.split(".").slice(1).reverse().join(".");
}
console.log(formatarTresEmTres(n1), formatarTresEmTres(n2), formatarTresEmTres(n3), formatarTresEmTres(n4), formatarTresEmTres(n5));
