以前工作，不忙的时候，用js面向对象的思想，写了一个操作cookie的类！
案例如下：
cache.class.js
/**提供客户端cookie操作类
*
* @param string uniqueN 唯一标识
*
*/
var cacheLY = function(uniqueN){
var uniqueN = (typeof(uniqueN) != \"string\") ? \"\" : \"uniqueN_\" + uniqueN + \"_\";
setCookie = function(name, value){
var Days = 1;
var exp = new Date();
exp.setTime(exp.getTime() + Days * 24 * 60 * 60 * 1000);
document.cookie = name + \"=\" + escape(this.encode(value)) + \";expires=\" + exp.toGMTString();
}
getCookie = function(name){
var arr = document.cookie.match(new RegExp(\"(^| )\" + name + \"=([^;]*)(;|$)\"));
if (arr != null)
return this.unencode(unescape(arr[2]));
return null;
}
delCookie = function(name){
var exp = new Date();
exp.setTime(exp.getTime() - 1);
var tem = this.getCookie(name);
if (tem != null)
document.cookie = \"name=\" + tem + \";expires=\" + exp.toGMTString();
}
encode = function(str){
var temstr = \"\";
var i = str.length - 1;
for (i; i >= 0; i--) {
temstr += str.charCodeAt(i);
if (i)
temstr += \"a\";
}
return temstr;
}
unencode = function(str){
var strarr = \"\";
var temstr = \"\";
strarr = str.split(\"a\");
var i = strarr.length - 1;
for (i; i >= 0; i--) {
temstr += String.fromCharCode(eval(strarr[i]));
}
return temstr;
}
return {
setValue: function(text){
setCookie(uniqueN, text);
},
clearCache: function(name){
delCookie(name);
},
loadCache: function(){
var temvalue = getCookie(uniqueN);
return temvalue;
}
}
}
