jQuery中获取当前cookie中的信息，cookie只是存在于客户端。想要取得图中 的数值，在jQuery获取。
1、获取当前的cookie信息
function getCookie(cookieName){
var cookieValue="";
if (document.cookie && document.cookie != '') {
var cookies = document.cookie.split(';');
for (var i = 0; i < cookies.length; i++) {
var cookie = cookies[i];
if (cookie.substring(0, cookieName.length + 2).trim() == cookieName.trim() + "=") {
cookieValue = cookie.substring(cookieName.length + 2, cookie.length);
break;
}
}
}
return cookieValue;
}
2、测试是否成功
$(document).ready(function(){
var skey = getCookie("ecology_JSessionId");
alert(test);
});
