When the application starts, I need to open a modal for the user to choose an environment, so I created a cookie in JS to store if it is the first time the user opened the application, follow the code:
window.onload = function() {
var cookies = document.cookie;
// Verifica se o cookie existe
if (cookies.indexOf("usuarioVisualizouModal") == -1) {
// Entra aqui caso o cookie não exista no navegador do usuário
// Crio um objeto Date do Javascript pegando a data de hoje e incrementando + 14 dias nessa data
var diasparaexpirar = 14;
var expiracao = new Date();
expiracao.setTime(expiracao.getTime() + (diasparaexpirar * 24 * 60 * 60 * 1000));
// Converte a data para string
expiracao = expiracao.toUTCString();
// Crio o cookie com a data de expiração
document.cookie = 'usuarioVisualizouModal=SIM; path=/';
// Exibo o modal
var url = '/Facility/ActiveFacility';
$('#ModalBody').html('<iframe width="100%" height="100%" frameborder="0" allowtransparency="true" src="' + url + '"></iframe>');
$("#OpenModal").modal("show");
}
};
I do not have experience with cookies, I studied it and got this sample code. In the code it expires the cookie in 14 days, I need the cookie to expire when the application is closed. I tried to use "Onunload" in the body of the layout, however it does not display the selection screen when opening the application again, I do not know if it is actually deleting the cookie. Here is the code I used in onunload:
No Body Code:
<body onunload="deleteCookie(usuarioVisualizouModal);">
Function:
function deleteCookie(nome){
var exdate = new Date();
exdate.setTime(exdate.getTime() + (-1 * 24 * 3600
* 1000));
document.cookie = nome + "=" + escape("")+ ((-1
== null) ? "" : "; expires=" + exdate);
}
Any solution?
ps: When I used OnUnload I removed the Expirate from the code that generates the cookie
