QQ浏览器设置cookie不成功是怎么回事？

Question

//关闭提示条
var CookieUtil={
    get:function(name){
        var cookieName=encodeURIComponent(name)+"=",
            cookieStart=document.cookie.indexOf(cookieName),
            cookieValue=null;
        if(cookieStart>-1){
            var cookieEnd=document.cookie.indexOf(";",cookieStart);
            if(cookieEnd==-1){
                cookieEnd=document.cookie.length;
            }
            cookieValue=decodeURIComponent(document.cookie.substring(cookieStart+cookieName.length,cookieEnd));
        }
        return cookieValue;
    }
};

var clo=document.getElementById("close");
var tst=document.getElementById("tishitiao");
EventUtil.addHandler(clo,"click",function(){
    tst.style.display="none";
    document.cookie=encodeURIComponent("closetst")+"="+encodeURIComponent("closetst");
});
setTimeout(function(){
    var cookie=CookieUtil.get("closetst"); //通过这些代码设置的cookie，ie8及火狐能正常读取，但是qq浏览器不知为什么读取不了，总是为null，这是为啥？
    if(cookie){
    tst.style.display="none";
    }
},0);

Answer 1

我建议使用jq的插件
jquery.cookie.js

Answer 2

用jquery.cookie.js好像也不行。
