应用js设置cookie于获取cookie

js设置cookie:

var ckval="1asd2323sdfe23";

var ckname= "xxxxxx";

var ocDate = new Date();

ocDate.setDate(ocDate.getDate() + 15);

document.cookie = ckname+ '=' + ckval
+ ";expires=" + ocDate + ";path=/";

js获取cookie:

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

function ckvalue() {
var userIds;
acookie.forEach(function(e) {
if (e.indexOf("xxxxxx") != -1) {
var val = e.split("=");
for ( var i = 0; i < val.length; i++) {
if ("xxxxxx" != val[i].trim()) {
userIds = val[i];
break;
}
}
}
});
return userIds;

}
