在JavaScript中,可以使用document.cookie属性将值附加到cookie。下面是一个完善且全面的答案:
将值附加到cookie的步骤如下:
function setCookie(name, value, days) {
var expires = "";
if (days) {
var date = new Date();
date.setTime(date.getTime() + (days * 24 * 60 * 60 * 1000));
expires = "; expires=" + date.toUTCString();
}
document.cookie = name + "=" + value + expires + "; path=/";
}
setCookie("username", "value", 7);
function getCookie(name) {
var nameEQ = name + "=";
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, c.length);
}
if (c.indexOf(nameEQ) == 0) {
return c.substring(nameEQ.length, c.length);
}
}
return null;
}
var username = getCookie("username");
这样,我们就可以在JavaScript中将值附加到cookie,并在需要时获取cookie的值。
