有没有用javascript清除cookie?
首先,我需要澄清问题。 StackOverflow中的许多帖子都提供this kind of answer。但它正在清除cookie,就像将所有键的值设置为空字符串一样。但我也需要擦除键。我怎么能这样做?
PS:我尝试了document.cookie = null
,但它不起作用here

我找到的最好方法是使您要删除的Cookie失效,请使用此javascript:
function createCookie(name,value,days) {
if (days) {
var date = new Date();
date.setTime(date.getTime()+(days*24*60*60*1000));
var expires = "; expires="+date.toGMTString();
}
else var expires = "";
document.cookie = name+"="+value+expires+"; path=/";
}
function readCookie(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;
}
function eraseCookie(name) {
createCookie(name,"",-1);
}
