I want to do the following step:
se (cookie[titulo] existe){
altera o valor dele para $valor
}se nao {
cria um com $valor
}
NOTE: I have a function that creates the cookie, called GerarCookie(nome,valor,tempo) .
Now, how to do this in javascript?
The code has the function of defining, reading and checking the cookie, very simple.
I hope you get a path:
<!DOCTYPE html>
<html>
<head>
<script>
function setCookie(cname,cvalue,exdays) {
var d = new Date();
d.setTime(d.getTime() + (exdays*24*60*60*1000));
var expires = "expires=" + d.toGMTString();
document.cookie = cname+"="+cvalue+"; "+expires;
}
function getCookie(cname) {
var name = cname + "=";
var ca = document.cookie.split(';');
for(var i=0; i<ca.length; i++) {
var c = ca[i];
while (c.charAt(0)==' ') c = c.substring(1);
if (c.indexOf(name) == 0) {
return c.substring(name.length, c.length);
}
}
return "";
}
function checkCookie() {
var user=getCookie("username");
if (user != "") {
alert("Welcome again " + user);
} else {
user = prompt("Please enter your name:","");
if (user != "" && user != null) {
setCookie("username", user, 30);
}
}
}
</script>
</head>
<body onload="checkCookie()">
</body>
</html>
window.onload = function () { checkCookie (); }
function checkCookie () { var user = getCookie ("user"); if (user!="") { alert ("Welcome" + username + "!"); } else { user = prompt ("Please enter your name:"); if ((user!="") & & (user! = null)) { setCookie ("user", user, 365); } } }
function setCookie (key, value, ValidityDays) { var validity = new Date (); validity.setTime (validity.getTime () + validityDays * 24 * 60 * 60 * 1000); var validityUTC="expires=" + validity.toUTCString (); document.cookie = key + "=" + value + ";" + validityUTC + "; path = /"; }
function getCookie (key) { var keyIgual = key + "="; var pairs = document.cookie.split (";"); for (let i = 0; i
