關于UTF8頁面中文COOKIE個人解決辦法：
1.使用cgi語言將中文轉換成unicode編碼，如"\u****"；
2.將unicode編碼寫入cookie；
3.使用js轉換此unicode，如：
unescape(CE.cookie.get("***").replace(/\\/g,"%"))
搞定！不知道還有沒有更好的解決方案，或者該方法是否存在一些漏洞問題？？

關于鏈接<a>上面直接寫javascript事件的問題，今天組內討論了一下，小寫一下：
常見的寫法有：
1.<a href="javascript:fun()"></a> //直接在href屬性中執行fun事件
2.<a href="javascript:void(0)" onclick = "fun();"></a> //在onclick屬性中執行fun事件
3.<a href="#" onclick = "fun();return false;"></a> //href屬性指向"#"，而onclick事件中return false阻止默認行為
最終投票決定使用第三種方法，前兩種方法在IE6都會是gif或其他可以動畫效果的東東靜止掉。。。具體原因應該是瀏覽器渲染問題吧，呵呵
第三種方法也有用到針對SEO方面的應用，比如我有一個連接是到一個靜態頁面a.html，但是由于需求方面的問題需要通過一個cgi再跳轉到a.html，如：b.cgi?uri=a.html，這樣的寫成：<a href="a.html" onclick="window.open('b.cgi?uri=a.html');return false;">XXX</a>表面上可以解決了問題，但是這種算不算是SEO的URL欺騙行為呢？

編輯 收藏主要功能：
1.拖動
2.可配置相對位置
3.平滑移動

if(p >= 1){
o.style[a] = e + "px";
callback && callback.call(o);
o = null;
return clearInterval(iTimer);
}

特點：
1.支持fn參數中使用this關鍵字
2.相同fn綁定無效
缺點：
非ie下不能直接使用匿名函數直接當參數傳遞，這個誰有比較好的解決辦法么？
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;
}
}
}
}
}
};
提升了一下執行效率：
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.匹配電話號碼(國內)
(?:\(?(?:[\+0]?)[0-9]+?[\)?-])?[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
