Question

My code :

var listaIDOrdine = new Array();
for (i = 0; i < 10; i++) {
    listaIDOrdine[i] == new CoppiaIDOrdine(1, 1);
    console.log(listaIDOrdine[i]);
}

function CoppiaIDOrdine(id, ordine) {
    this.id = id;
    this.id = ordine;
}

but I get 10 undefined! What is wrong? I expect to have the “couple” of item at every console.log().

Also tried with console.log(listaIDOrdine[i].id); but seems that id is undefined?

Answer 1

You are using == (comparison operator) when you should be using = (assignment operator):

listaIDOrdine[i] = new CoppiaIDOrdine(1, 1);

Also, you could use Array#push instead to add elements to the array:

listaIDOrdine.push(new CoppiaIDOrdine(1, 1));
