关于UTF8页面中文COOKIE个人解决办法：
1.使用cgi语言将中文转换成unicode编码，如"\u****"；
2.将unicode编码写入cookie；
3.使用js转换此unicode，如：
unescape(CE.cookie.get("***").replace(/\\/g,"%"))
搞定！不知道还有没有更好的解决方案，或者该方法是否存在一些漏洞问题？？

关于链接<a>上面直接写javascript事件的问题，今天组内讨论了一下，小写一下：
常见的写法有：
1.<a href="javascript:fun()"></a> //直接在href属性中执行fun事件
2.<a href="javascript:void(0)" onclick = "fun();"></a> //在onclick属性中执行fun事件
3.<a href="#" onclick = "fun();return false;"></a> //href属性指向"#"，而onclick事件中return false阻止默认行为
最终投票决定使用第三种方法，前两种方法在IE6都会是gif或其他可以动画效果的东东静止掉。。。具体原因应该是浏览器渲染问题吧，呵呵
第三种方法也有用到针对SEO方面的应用，比如我有一个连接是到一个静态页面a.html，但是由于需求方面的问题需要通过一个cgi再跳转到a.html，如：b.cgi?uri=a.html，这样的写成：<a href="a.html" onclick="window.open('b.cgi?uri=a.html');return false;">XXX</a>表面上可以解决了问题，但是这种算不算是SEO的URL欺骗行为呢？

1.拖动
2.可配置相对位置
3.平滑移动

特点：
1.支持fn参数中使用this关键字
2.相同fn绑定无效
缺点：
非ie下不能直接使用匿名函数直接当参数传递，这个谁有比较好的解决办法么？
CE.Event = 
{
handler : function(e){
e = e || window.event;
var _fn = "_" + e.type;
if(this[_fn]){
for(var _f in this[_fn]){
this[_fn][_f].call(this,e);
}
}
},
bind : function(obj, act, fn, capture){
if(window.addEventListener){
obj.addEventListener(act,fn,capture || false);
}else{
var _fn = "_" + act;
act = "on" + act;
if(!obj[_fn]){
obj[_fn] = [];
obj[act] = CE.Event.handler;
}else{
for(var _f in obj[_fn]){
if(obj[_fn][_f].toString() === fn.toString()){return};
}
}
obj[_fn][obj[_fn].length] = fn;
}
},
unbind : function(obj, act, fn, capture){
if(window.removeEventListener){
obj.removeEventListener(act,fn,capture || false);
}else{
var _fn = "_" + act;
if(obj[_fn]){
for(var _f in obj[_fn]){
if(obj[_fn][_f].toString() === fn.toString()){
try{
delete obj[_fn][_f];
}catch(e){
obj[_fn][_f] = null;
}
return;
}
}
}
}
}
};
提升了一下执行效率：
CE.Event = {
ecount : 1,
handler : function(e){
e = e || window.event;
if(this.evns[e.type]){
for(var evn in this.evns[e.type]){
this.evns[e.type][evn].call(this,e);
}
}
},
bind : function(obj, act, fn, capture){
if(window.addEventListener){
obj.addEventListener(act,fn,capture || false);
}else{
if(!fn.id){fn.id = CE.Event.ecount++};
if(!obj.evns){obj.evns = {}};
if(!obj.evns[act]){
obj.evns[act] = {};
if(obj["on" + act]){
obj.evns[act][0] = obj["on" + act];
}
}else{
for(var evn in obj.evns[act]){
if(evn.id === fn.id){return;}
}
}
obj.evns[act][fn.id] = fn;
obj["on" + act] = CE.Event.handler;
}
},
unbind : function(obj, act, fn, capture){
if(window.removeEventListener){
obj.removeEventListener(act,fn,capture || false);
}else{
if(obj.evns && obj.evns[act]){
try{
delete obj.evns[act][fn.id];
}catch(e){
obj.evns.act[fn.id] = null;
}
return;
}
}
}
};

1.匹配电话号码(国内)
(?:\(?(?:[\+0]?)[0-9]+?[\)?-])?[0-9]{3,4}(?:-?)[0-9]{7,8}(?:(?:-?)[0-9]+)?
匹配：01012345678，010-12345678，+86-010-12345678，(86)010-1234567，(086)010-12345678 等等

新写了一个兼容ie，ff的Storage类，主要实现：
1.存储，
2.获取，
3.删除，
数据支持字符串/json
以下是源码：
Storage = (function(){
var isInit = false;
var obj = null;
var defDay = 365;
var isIE = ("\v" == "v");
var ikey = "Tenpay_Default_Data";
var domain = document.domain; //或者提取自己框架的
var initObj = function(){
if(isIE){
obj = document.createElement("div");
obj.id = "Default_JData_id";
obj.style.behavior = "url('#default#userData')"
document.body.appendChild(obj);
isInit = true;
}
};
var setExpire = function(day){
defDay = day;
};
var jsonToStr = function(json){
var list = [];
if("string" === typeof(json)) return "\""+ json.replace(/([\'\"\\])/g,"\\$1").replace(/(\n)/g,"\\n").replace(/(\r)/g,"\\r").replace(/(\t)/g,"\\t")+"\"";
if("number" === typeof(json)) return json;
if("undefined" === typeof(json)) return "undefined";
if("object" === typeof(json)){
if(null === json){return null}
else if("function" === typeof(json.sort)){
for(var i = 0,len = json.length; i < len; i++){
list.push(jsonToStr(json[i]));
}
return "["+ list.join() +"]";
}else{
for(var i in json){
list.push(i + ":" + jsonToStr(json[i]));
}
return "{"+ list.join() +"}";
}
}
};
var strToJson = function(str){
return eval('('+ str +')');
};
var setData = function(name, value, domain_name, key, day){
ikey = key || ikey;
domain = domain_name || domain;
if(!isInit){initObj()};
if(value instanceof Object){
value = jsonToStr(value);
}
var d = new Date(),exps = (null != day ? day : defDay);
d.setSeconds(d.getSeconds() + exps * 24 * 3600);
try{if(isIE){
obj.load(ikey);
obj.setAttribute(name, value);
obj.expires = d.toUTCString();
obj.save(ikey);
}else if(window.globalStorage){
globalStorage[domain][ikey + "__" + name] = value;
globalStorage[domain][ikey + "__expire"] = d.getTime();
}}catch(e){}
};
var getData = function(name, domain_name, key){
ikey = key || ikey;
domain = domain_name || domain;
if(!isInit){initObj()};
try{
if(isIE){
obj.load(ikey);
return /^\{.*\}$|^\[.*\]$/.test(obj.getAttribute(name)) ? strToJson(obj.getAttribute(name)) : obj.getAttribute(name);
}else if(window.globalStorage){
var now = parseFloat((new Date()).getTime()), exp = parseFloat(globalStorage[domain][ikey + "__expire"]);
if (exp > now) {
return /^\{.*\}$|^\[.*\]$/.test(globalStorage[domain][ikey + "__" + name]) ? strToJson(globalStorage[domain][ikey + "__" + name]) : globalStorage[domain][ikey + "__" + name];
}else {
delData(name, key);
}
}
}catch(e) {
//exception
}
return "";
};
var delData = function(name, domain_name, key){
ikey = key || ikey;
domain = domain_name || domain;
if(!isInit){initObj()};
try {
if(isIE){
obj.load(ikey);
obj.removeAttribute(name);
obj.save(ikey);
}else if(window.globalStorage){
globalStorage[domain][ikey + "__" + name] = undefined;
globalStorage[domain].removeItem(ikey + "__" + name);
}
}catch (e) {}
};
return {
setExp : setExpire,
set : setData,
get : getData,
del : delData
};
})();

https协议空请求ie下报安全警告，很纠结的问题啊，
比如我使用一个<iframe>，src属性为：about:blank,javascript:void(0),javascript://在ie下都会报安全警告，
后来发现了一个hack，javascript:''，以为终于可以自喜，上线后居然xp sp2又报错了，本来最近老是出错，又出现了这个BUG，真的是要吐血了，没办法还是改回了指向一个空白页面
难道就没有更好的办法了么？
