If its necessary to get from the JavaScript array unique values only:

function onlyUniqueArray(value, index, self) {
    return self.indexOf(value) === index;
}
var arr_unique_values = arr_values.filter(onlyUniqueArray);

function onlyUniqueArray(value, index, self) {

return self.indexOf(value) === index;

}

var arr_unique_values = arr_values.filter(onlyUniqueArray);
