Copy Code code as follows:
function ClearCookie () {
var expires = new Date ();
Expires.settime (Expires.gettime ()-1000); The current time minus one second, equivalent to immediate expiration (can increase or decrease)
Document.cookie = "appcode= ' 222 '" ";p ath=/;expires=" + expires.togmtstring () + ""; Expires is a setting that corresponds to the expiration time, and does not set this value, the cookie defaults when the browser is closed
Document.cookie = "roleid= ' 333 '" ";p ath=/;expires=" + expires.togmtstring () + "";
Document.cookie = "parentmenuid= '" ';p ath=/;expires= "+ expires.togmtstring () +" ";
Document.cookie = "currentmenuname= ' haha '" ';p ath=/;expires= "+ expires.togmtstring () +" ";
}
path=/: The location where the cookie resides is the browser root directory
This method causes appcode,roleid,parentmenuid,currentmenuname4 cookies to fail
