我写了一个小的javascript函数
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) != -1) return c.substring(name.length, c.length);
}
return "";
}
function deleteCookie(key)
{
// Delete a cookie by setting the date of expiry to yesterday
date = new Date();
date.setDate(date.getDate() -1);
document.cookie = escape(key) + '=;expires=' + date;
}
在我的控制台中.i通过document.cookie =&#34;设置一个cookie;下一个= true&#34 ;; 我打电话给getCookie(&#39; Next&#39;)。返回true 我打电话给deleteCookie(&#39; Next&#39;)然后调用getCookie(&#39; Next&#39;)仍然返回true.can任何人请告诉为什么它不删除cookie ??

试试这个:
function deleteCookie(key) {
document.cookie =
encodeURIComponent(key) +
"=deleted; expires=" +
new Date(0).toUTCString();
}

使用JQuery删除cookie
//To set a cookie
02
$.cookie('the_cookie', 'the_value');
03
04
//Create expiring cookie, 7 days from then:
05
$.cookie('the_cookie', 'the_value', { expires: 7 });
06
07
//Create expiring cookie, valid across entire page:
08
$.cookie('the_cookie', 'the_value', { expires: 7, path: '/' });
09
10
//Read cookie
11
$.cookie('the_cookie'); // => 'the_value'
12
$.cookie('not_existing'); // => null
13
14
//Delete cookie by passing null as value:
15
$.cookie('the_cookie', null);
16
17
// Creating cookie with all availabl options
18
$.cookie('myCookie2', 'myValue2', { expires: 7, path: '/', domain: 'example.com',
19
secure: true, raw: true });

也设置cookie的域对我有用:
document.cookie = 'cookiename=; Max-Age=0; path=/; domain=.example.com';
