Does document.cookie only work on a server? Alert doesn't seem to be outputting my cookie.

document.cookie = "d=e";
alert(document.cookie);

解决方案

Some browsers won't honor cookies when set by a document with the file protocol.

Chrome intentionally disables cookies on file://, for a variety of reasons. When we wrote our cookie support, the correct behavior was unclear when dealing with things like file shares. We found cookies on file:// to be fairly uncommon, and it has a few negative security implications.

You can, however, enable them with the command line flag --enable-file-cookies.

Cookies are strictly a HTTP mechanism as per RFC 2109. There should be no reasonable expectation for them to work for protocols other than HTTP, much less file:///, and it is not clear what their behavior should be, and what rules of security compartmentalization should apply.
