I made a code js so that every week the specific advertising banner is changed, in case every Sunday one banner is exchanged for the other.
I started doing Javascript , but within the r == 0 compare function document.byelementbyid with style.display was not working.
They are working fine, I have done some tests but if it can be simplified it would be great, I'm not sure how to create the weeks.
$(document).ready(function() {
var d = new Date();
var weekday = new Array(7);
weekday[0] = 'Domingo';
weekday[1] = 'Segunda';
weekday[2] = 'Terça';
weekday[3] = 'Quarta';
weekday[4] = 'Quinta';
weekday[5] = 'Sexta';
weekday[6] = 'Sabado';
var n = weekday[d.getDay()];
function virada() {
var i = 0;
var r = i % 2;
if (n == weekday[0]) {
i++;
}
if (r == 0) {
$('#bn1').show();
} else {
$('#bn2').show();
}
}
virada();
});#bn1,
#bn2 {
display: none;
