如何使用JavaScript删除当前域的所有cookie ?
当前回答
如果你有jquery的访问。Cookie插件,你可以用这种方式删除所有的Cookie:
for (var it in $.cookie()) $.removeCookie(it);

在测试了多种浏览器中列出的几乎所有方法后,我发现几乎没有一种方法能达到50%的效果。
如果需要,请帮忙纠正,但我要在这里发表我的意见。下面的方法分解了所有内容,基本上基于设置部分构建cookie值字符串,并包括路径字符串的一步一步构建,当然从/开始。
希望这对其他人有所帮助,我希望任何批评都能以完善这种方法的形式出现。起初,我想要一个简单的1-liner,因为有些人寻求,但JS cookie是那些不那么容易处理的事情之一。
;(function() {
if (!window['deleteAllCookies'] && document['cookie']) {
window.deleteAllCookies = function(showLog) {
var arrCookies = document.cookie.split(';'),
arrPaths = location.pathname.replace(/^\//, '').split('/'), // remove leading '/' and split any existing paths
arrTemplate = [ 'expires=Thu, 01-Jan-1970 00:00:01 GMT', 'path={path}', 'domain=' + window.location.host, 'secure=' ]; // array of cookie settings in order tested and found most useful in establishing a "delete"
for (var i in arrCookies) {
var strCookie = arrCookies[i];
if (typeof strCookie == 'string' && strCookie.indexOf('=') >= 0) {
var strName = strCookie.split('=')[0]; // the cookie name
for (var j=1;j<=arrTemplate.length;j++) {
if (document.cookie.indexOf(strName) < 0) break; // if this is true, then the cookie no longer exist
else {
var strValue = strName + '=; ' + arrTemplate.slice(0, j).join('; ') + ';'; // made using the temp array of settings, putting it together piece by piece as loop rolls on
if (j == 1) document.cookie = strValue;
else {
for (var k=0;k<=arrPaths.length;k++) {
if (document.cookie.indexOf(strName) < 0) break; // if this is true, then the cookie no longer exist
else {
var strPath = arrPaths.slice(0, k).join('/') + '/'; // builds path line
strValue = strValue.replace('{path}', strPath);
document.cookie = strValue;
}
}
}
}
}
}
}
showLog && window['console'] && console.info && console.info("\n\tCookies Have Been Deleted!\n\tdocument.cookie = \"" + document.cookie + "\"\n");
return document.cookie;
}
}
})();
这对我来说很管用:
function deleteCookie(name) {
document.cookie =
`${name}=; Expires=Thu, 01 Jan 1970 00:00:01 GMT; Path=/`;
// Remove it from local storage too
window.localStorage.removeItem(name);
}
function deleteAllCookies() {
const cookies = document.cookie.split("; ");
cookies.forEach((cookie) => {
const name = cookie.split("=").shift();
this.deleteCookie(name);
});
// Some sites backup cookies in `localStorage`
window.localStorage.clear();
}
function deleteAllCookies() {
const cookies = document.cookie.split(";");
for (let i = 0; i < cookies.length; i++) {
const cookie = cookies[i];
const eqPos = cookie.indexOf("=");
const name = eqPos > -1 ? cookie.substr(0, eqPos) : cookie;
document.cookie = name + "=;expires=Thu, 01 Jan 1970 00:00:00 GMT";
}
}
注意,这段代码有两个限制:
它不会删除设置了HttpOnly标志的cookie,因为HttpOnly标志禁止Javascript访问cookie。 它不会删除已设置为Path值的cookie。(尽管这些cookie会出现在文档中。cookie,但你不能删除它没有指定相同的路径值,它是设置。)
你可以通过查看文档得到一个列表。饼干变量。清除它们只是一个循环遍历所有它们并一个一个地清除它们的问题。
document.cookie.split(";").forEach(function(c) {
document.cookie = c.replace(/^ +/, "").replace(/=.*/, "=;expires=" + new Date().toUTCString() + ";path=/");
});
//clearing local storage
localStorage.clear();
