Are some commonly used functions, there is no more nonsense, small partners to see their own understanding

The code:

Copy Code code as follows:

Cookies
function Setcookie (name, value, Iday)
{
if (Iday!==false)
{
var odate=new Date ();

}
Else
{
document.cookie=name+ ' = ' +value;
}
}
function GetCookie (name)
{
var arr=document.cookie.split ('; ');
var i=0;
for (i=0;i<arr.length;i++)

}
}

}
function Removecookie (name)
