大家好，我正在尝试创建 cookie，但没有成功。这是我的站点代码，我不知道为什么我无法获取我创建的 cookie？

        <div id="button"><input type="submit" value="Press me please!" /></div>
        <div id="button"><input type="submit" value="Cookie!" onclick=getCookie('myCookie'); /></div>
    </center>
    <div id="popupContact"></div>
    <div id="backgroundPopup"></div>
</body>
</html>

以及似乎不起作用的cookie创建：

<body onload="setCookie('myCookie', 'myValue', 1);">

那么这里的问题是什么？

试试这个代码：

<!DOCTYPE html>
<html>
<head>
<script>
       function setCookie(name,value,days) {
            if (days) {
            var date = new Date();
            date.setTime(date.getTime()+(days*24*60*60*1000));
            var expires = "; expires="+date.toGMTString();
            }
            else var expires = "";
            document.cookie = name+"="+value+expires+"; path=/";
        }

        function getCookie(name) {
            var nameEQ = name + "=";
            var ca = document.cookie.split(';');
            for(var i=0;i < ca.length;i++) {
            var c = ca[i];
            while (c.charAt(0)==' ') c = c.substring(1,c.length);
            if (c.indexOf(nameEQ) == 0) return c.substring(nameEQ.length,c.length);
            }
            return null;
        }

        function deleteCookie(name) {
            setCookie(name,"",-1);
        }

        function clickMe() {
           alert(getCookie('myCookie'));
        }
</script>
</head>

<body onload="setCookie('myCookie', 'myValue', 1);">
<input type="button" onClick="clickMe()" value="test" />
</html>

这里的问题是cookie 不能在 Chrome 本地工作！用 Firefox 试过，效果很好。如果您想查看它的实际效果，您必须将文件上传到服务器或本地主机并查看它在 Chrome 中的工作方式。

试试这个代码 

function setCookie(name,value,days)
{
var date=new Date();
var exdays = days*24*60*60*1000;
date.setDate(date.getDate() + exdays);
var c_value=escape(value) + ((days==null) ? "" : "; expires="+date.toUTCString());
document.cookie=name + "=" + c_value;
}    

function getCookie(c_name)
{
var i,x,y,ARRcookies=document.cookie.split(';');
 for (i=0; i < ARRcookies.length;i++)
{
x=ARRcookies[i].substr(0,ARRcookies[i].indexOf('='));
y=ARRcookies[i].substr(ARRcookies[i].indexOf("=")+1);
x=x.replace(/^\s+|\s+$/g,"");
if (x==c_name)
{
return unescape(y);
}
}
}

function deleteCookie(name) {
        setCookie(name,"",-1);
    }

    function clickMe() {
       alert(getCookie('myCookie'));
    }
