重定向前删除cookie后无法检索javascript cookie

Question

My page HTML contains a span (with text) whose onClick = "goDropShip();"

The page contains a script that contains:

function goDropShip() {

    var date = new Date();
    date.setTime(date.getTime()+(24*60*60*1000));
    document.cookie = "dropShip=true; expires="+date.toGMTString();
    window.location.href="http://www.domain.com";

}

I have verified, with " alert() ", that the function is in fact executing. And testing the cookie immediately after dropping it is successful. However, after the redirect, the cookie seems to be empty.

www.domain.com's index.html (which receives this redirect) has a script with the following:

if (document.cookie.indexOf("dropShip=true") >= 0  ) {
    window.location = "http://www.domain.com/processDropShip";
}

However, the cookie appears to be completely blank after the redirect.

I am trying .indexOf() only because attempts to retrieve the cookie specifically by name have also failed, so I am trying to find the cookie in the entire document.cookie text.

I am probably just not using the cookies properly, or I do not know how to.

Forgive the fact that "dropShip" doesn't seem to make sense in this context, but I am having to obfuscate the details for security reasons. But the only thing I have changed is the cookie name.

As always, thanks for any help.

如果您要设置Cookie的域和重定向到的域相同，则在添加Cookie时只需将路径设置为/即可在整个域中访问它。

document.cookie = "dropShip=true; path=/; expires="+date.toGMTString();
