Set cookie (with JS) for whole domain not specific page
提问by Sheixt
I have a simple little script which I am using to set a cookie:
我有一个简单的小脚本，用于设置 cookie：
function setCookie(cname, cvalue, exdays) {
var d = new Date();
d.setTime(d.getTime() + (exdays*24*60*60*1000));
var expires = "expires="+d.toUTCString();
document.cookie = cname + "=" + cvalue + "; " + expires;
}
The problem I have this cookie is only set on one page, not across the whole domain.
我有这个 cookie 的问题只设置在一个页面上，而不是整个域。
How can I adjust this function so that the cookie remains across the whole domain?
如何调整此功能以使 cookie 保留在整个域中？

You can specifiy domain ;domain=.example.comas well as path ;path=/("/" set cookie in whole domain)
您可以指定域;domain=.example.com和路径;path=/（“/”在整个域中设置 cookie）
document.cookie = cname + "=" + cvalue + "; " + expires +";path=/";
