javascript 24钟头弹出一回的代码_广告代码_脚本之家

复制代码 代码如下:function jb51tuitan(){ if (getCookie{ //要执行的代码或一些操作setCookie;//写入cookies表示已经执行过了。alert; } } jb51tuitan() function setCookie { var argv = setCookie.arguments; var argc = setCookie.arguments.length; var expires = ? argv[2] : null; if { var LargeExpDate = new Date (); LargeExpDate.setTime(LargeExpDate.getTime() + ); } document.cookie = name + "=" + escape + ? "" : ("; expires=" +LargeExpDate.toGMTString; } function getCookie { var search = Name + "=" if(document.cookie.length > 0) { offset = document.cookie.indexOf if { offset += search.length end = document.cookie.indexOf if end = document.cookie.length return unescape(document.cookie.substring } else return "" } } 把想要输出的内容,放到jb51tuitan()函数里面的判断语句里面即可。

第一种方法:cookie操作类,代码封装了,下面也有使用方法,大家可以参考下。

复制代码 代码如下:

String.prototype.Trim = function()
{
return this.replace(/^s+/g,"").replace(/s+$/g,"");
}
function JSCookie()
{
this.GetCookie = function(key)
{
var cookie = document.cookie;
var cookieArray = cookie.split(';');
var getvalue = "";
for(var i = 0;i<cookieArray.length;i++)
{
if(cookieArray[i].Trim().substr(0,key.length) == key)
{
getvalue = cookieArray[i].Trim().substr(key.length + 1);
break;
}
}
return getvalue;
};
this.GetChild = function(cookiekey,childkey)
{
var child = this.GetCookie(cookiekey);
var childs = child.split('&');
var getvalue = "";
for(var i = 0;i < childs.length;i++)
{
if(childs[i].Trim().substr(0,childkey.length) == childkey)
{
getvalue = childs[i].Trim().substr(childkey.length + 1);
break;
}
}
return getvalue;
};
this.SetCookie = function(key,value,expire,domain,path)
{
var cookie = "";
if(key != null && value != null)
cookie += key + "=" + value + ";";
if(expire != null)
cookie += "expires=" + expire.toGMTString() + ";";
if(domain != null)
cookie += "domain=" + domain + ";";
if(path != null)
cookie += "path=" + path + ";";
document.cookie = cookie;
};
this.Expire = function(key)
{
expire_time = new Date();
expire_time.setFullYear(expire_time.getFullYear() - 1);
var cookie = " " + key + "=e;expires=" + expire_time + ";"
document.cookie = cookie;
}
}

用法:
一、设置cookie
var cookie = new JSCookie();
//普通设置
cookie .SetCookie("key1","val1");
//过期时间为一年
var expire_time = new Date();
expire_time.setFullYear(expire_time.getFullYear() + 1);
cookie .SetCookie("key2","val2",expire_time);
//设置域及路径,带过期时间
cookie .SetCookie("key3","val3",expire_time,".cnblogs.com","/");
//设置带子键的cookie,子键分别是k1,k2,k3
cookie .SetCookie("key4","k1=1&k2=2&k3=3");
二、读取cookie
//简单获取
cookie .GetCookie("key1");
cookie .GetCookie("key2");
cookie .GetCookie("key3");
cookie .GetCookie("key4");
//获取key4的子键k1值
cookie .GetChild("key4","k1");
三、删除 cookie .Expire("key1");
cookie .Expire("key2");
cookie .Expire("key3");
cookie .Expire("key4");
第二种方法:cookie操作函数,脚本之家也是用的这个。大家可以根据需要选择。

复制代码 代码如下:

function setCookie(name, value) //cookies设置JS
{
var argv = setCookie.arguments;
var argc = setCookie.arguments.length;
var expires = (argc > 2) ? argv[2] : null;
if(expires!=null)
{
var LargeExpDate = new Date ();
LargeExpDate.setTime(LargeExpDate.getTime() + (expires*1000*3600*24));
}
document.cookie = name + "=" + escape (value)+((expires == null) ? "" : ("; expires=" +LargeExpDate.toGMTString()));
}
