创建cookie时，请使用“ path”参数。目录或网页的路径设置cookie。如果要从当前页面检索cookie，则该字段可以为空白。默认情况下，cookie属于当前页面。
要列出当前页面的所有cookie，请尝试以下代码-
<html>
<head>
<script>
function ReadCookie() {
var allcookies = document.cookie;
document.write ("All Cookies : " + allcookies );
// Get all the cookies pairs in an array
cookiearray = allcookies.split(';');
// Now take key value pair out of this array
for(var i=0; i<cookiearray.length; i++) {
name = cookiearray[i].split('=')[0];
value = cookiearray[i].split('=')[1];
document.write ("Key is : " + name + " and Value is : " + value);
}
}
</script>
</head>
<body>
<form name="myform" action="">
<p> click the following button and see the result:</p>
<input type="button" value="Get Cookie" onclick="ReadCookie()"/>
</form>
</body>
</html>
