return true;
else{
alert("浏览器配置错误,Cookie不可用!");

SetCookie('cookie_test','1');
var cookie_test = getCookie('cookie_test');
if( '1' != cookie_test)
{
alert('不支持');
}else

alert('支持');
}
function SetCookie(name,value)//两个参数,一个是cookie的名子,一个是值
{
var Days = 30; //此 cookie 将被保存 30 天
var exp = new Date(); //new Date("December 31, 9998");
exp.setTime(exp.getTime() + Days*24*60*60*1000);
document.cookie = name + "="+ escape (value) + ";expires=" + exp.toGMTString();
}
function getCookie(name)//取cookies函数
{
var arr = document.cookie.match(new RegExp("(^| )"+name+"=([^;]*)(;|$)"));
if(arr != null) return unescape(arr[2]); return null;
}
function delCookie(name)//删除cookie
{
var exp = new Date();
exp.setTime(exp.getTime() - 1);
var cval=getCookie(name);
if(cval!=null) document.cookie= name + "="+cval+";expires="+exp.toGMTString();
}
3.
var cookieEnabled=(navigator.cookieEnabled)? true : false
//判断cookie是否开启
//如果浏览器不是ie4+或ns6+
if (typeof navigator.cookieEnabled=="undefined" && !cookieEnabled){
document.cookie="testcookie"
cookieEnabled=(document.cookie=="testcookie")? true : false
document.cookie="" //erase dummy value
}
