求解cookie怎么清

Question

document.cookie = key=''; expires=${new Date(new Date().getTime() + new Date().setTime(-1 * 1000 * 3600 * 24)).toUTCString()}

这是一个已有成熟解决方案的问题。function deleteAllCookies() {&nbsp; &nbsp; var cookies = document.cookie.split(";");&nbsp; &nbsp; for (var i = 0; i < cookies.length; i++) {&nbsp; &nbsp; &nbsp; &nbsp; var cookie = cookies[i];&nbsp; &nbsp; &nbsp; &nbsp; var eqPos = cookie.indexOf("=");&nbsp; &nbsp; &nbsp; &nbsp; var name = eqPos > -1 ? cookie.substr(0, eqPos) : cookie;&nbsp; &nbsp; &nbsp; &nbsp; document.cookie = name + "=;expires=Thu, 01 Jan 1970 00:00:00 GMT";&nbsp; &nbsp; }}
