偶尔发现ExtJS中有操作cookie的js方法，拿来给大家分享下。
var Cookies = {};
Cookies.set = function(name, value){
var argv = arguments;
var argc = arguments.length;
var expires = (argc > 2) ? argv[2] : null;
var path = (argc > 3) ? argv[3] : '/';
var domain = (argc > 4) ? argv[4] : null;
var secure = (argc > 5) ? argv[5] : false;
document.cookie = name + "=" + escape (value) +
((expires == null) ? "" : ("; expires=" + expires.toGMTString())) +
((path == null) ? "" : ("; path=" + path)) +
((domain == null) ? "" : ("; domain=" + domain)) +
((secure == true) ? "; secure" : "");
};
Cookies.get = function(name){
var arg = name + "=";
var alen = arg.length;
var clen = document.cookie.length;
var i = 0;
var j = 0;
while(i < clen){
j = i + alen;
if (document.cookie.substring(i, j) == arg)
return Cookies.getCookieVal(j);
i = document.cookie.indexOf(" ", i) + 1;
if(i == 0)
break;
}
return null;
};
Cookies.clear = function(name) {
if(Cookies.get(name)){
document.cookie = name + "=" +
"; expires=Thu, 01-Jan-70 00:00:01 GMT";
}
};
Cookies.getCookieVal = function(offset){
var endstr = document.cookie.indexOf(";", offset);
if(endstr == -1){
endstr = document.cookie.length;
}
return unescape(document.cookie.substring(offset, endstr));
};
