//===========以下是针对项目写的对COOKIE的操作======================
//按复选框时改变COOKIE的状态
function changeCookie(obj,cookieName)
{
if(obj.checked==true){
setCookie(cookieName,1);
}else if(obj.checked==false){
delCookie(cookieName);
}
alert(document.cookie);
}
//设置对应复选框的COOKIE的值,当cookieName为1时设为选中状态
function allCookie()
{alert(document.cookie);
var checkboxList=document.getElementsByName("keyid[]");
for(var i=0;i<checkboxList.length;i++){
getCookie(checkboxList[i].value);
if(getCookie(checkboxList[i].value)==1){
checkboxList[i].checked=true;
}
}
}
