简单的Javascript Cookie操作

<mce:script type="text/javascript"><!--

function SetCookie(name,value,expire) {
var exp = new Date();
exp.setTime(exp.getTime() + expire);
document.cookie = name + "="+ escape (value) + ";expires=" + exp.toGMTString();
}

function getCookie(name) {
var arr = document.cookie.match(new RegExp("(^| )"+name+"=([^;]*)(;|$)"));
if(arr != null) return unescape(arr[2]); return null;
}

function delCookie(name){
var exp = new Date();
exp.setTime(exp.getTime() - 1);
var cval=getCookie(name);
if(cval!=null) document.cookie= name + "="+cval+";expires="+exp.toGMTString();
}
// --></mce:script>
JavaScript Cookie封装类源码
String.prototype.format = function() {
var s = this;
for (var i = 0, j = arguments.length; i < j; i++)
s = s.replace("{" + (i) + "}", arguments[i]);
return(s);
}
var Cookie = {
Set : function () {
var name = arguments[0], value = escape(arguments[1]),
days = (arguments.length > 2) ? arguments[2] : 365,
path = (arguments.length > 3) ? arguments[3] : "/";
with(new Date()) {
setDate(getDate() + days);
days = toUTCString();
}
document.cookie = "{0}={1};expires={2};path={3}".format(name, value, days, path);
},
Get : function () {
var returnValue = document.cookie.match(new RegExp("[\b\^;]?" + arguments[0] + "=([^;]*)(?=;|\b|$)","i"));
return returnValue ? unescape(returnValue[1]) : returnValue;
},
Delete : function () {
var name = arguments[0];
document.cookie = name + "=1 ; expires=Fri, 31 Dec 1900 23:59:59 GMT;";
}
}
使用方法：
<mce:script type="text/javascript"><!--
Cookie.Set("MyCookie", "Cookie值");
Cookie.Get("MyCookie");
Cookie.Delete("
