在 Javascript 中设置多个 cookie

我正在尝试设置多个 cookiedocument.cookie，但不幸的是只有一个被添加。

我知道网上有多个设置此类 cookie 的示例，我遵循了其中之一。但我仍然无法解决这个问题。 我跟着这个link http://www.elated.com/articles/javascript-and-cookies/设置我的cookie。

My Code:

   function setCookie(start_time,end_session_time,total_time,flag,count){
     var cookie_string = "start_time="+start_time;;

    if(end_session_time) {
        cookie_string +="; end_session_time="+end_session_time;
    }

    if(total_time){
        cookie_string +="; total_time="+total_time;
    }
    if(flag){
        cookie_string +="; flag="+flag;
    }
    if(count){
        cookie_string +="; count="+count;
    }

    document.cookie =cookie_string ;
    console.log(cookie_string);

    console.log("document.cookie ="+ document.cookie);
}

输出：

cookie_string :: start_time=1369926508266; flag=1; count=1
document.cookie =start_time=1369926508266; 

添加 cookie 是通过以下方式执行的document.cookie = "name=value"要添加多个键，您应该执行多次分配

function setCookie(start_time, end_session_time, total_time, flag, count) {
    document.cookie = "start_time=" + start_time;

    if (end_session_time) {
        document.cookie = "end_session_time=" + end_session_time;
    }
    if (total_time) {
        document.cookie = "total_time=" + total_time;
    }
    if (flag) {
        document.cookie = "flag=" + flag;
    }
    if (count) {
        document.cookie = "count=" + count;
    }

    console.log("document.cookie = " + document.cookie);
}
