求解cookie怎么清

Question

document.cookie = key=''; expires=${new Date(new Date().getTime() + new Date().setTime(-1 * 1000 * 3600 * 24)).toUTCString()}我查了下, 说设置过期时间, 但是试了下没成功

Answer 1

这是一个已有成熟解决方案的问题。

function deleteAllCookies() {

    var cookies = document.cookie.split(";");

    for (var i = 0; i < cookies.length; i++) {

        var cookie = cookies[i];

        var eqPos = cookie.indexOf("=");

        var name = eqPos > -1 ? cookie.substr(0, eqPos) : cookie;

        document.cookie = name + "=;expires=Thu, 01 Jan 1970 00:00:00 GMT";

    }

}
