问题描述

如何在 JavaScript 中创建会话?

How to create session in JavaScript?

我是这样尝试的:

<script type="text/javascript" >
{
Session["controlID"] ="This is my session";
}
</script> 

我为什么要找会话?

我使用 AJAX 请求 XML.我想在会话中存储 XML 响应，而这个会话我想传递给服务器页面 (.asp).我的意思是写一些类似的东西:

I make a request for XML using AJAX. XML response I want to store in session and this session I want to pass to the server page(.asp). I mean to write something like:

<% response.write session("MySession")%>

推荐答案

您可以在 cookie 中存储和读取字符串信息.

You can store and read string information in a cookie.

如果是来自服务器的会话ID，服务器可以生成这个cookie.当另一个请求发送到服务器时，cookie 也会出现.无需在浏览器中执行任何操作.

If it is a session id coming from the server, the server can generate this cookie. And when another request is sent to the server the cookie will come too. Without having to do anything in the browser.

但是，如果它是创建会话 ID 的 javascript.您可以使用 javascript 创建一个 cookie，其函数类似于:

However if it is javascript that creates the session Id. You can create a cookie with javascript, with a function like:

function writeCookie(name,value,days) {
    var date, expires;
    if (days) {
        date = new Date();
        date.setTime(date.getTime()+(days*24*60*60*1000));
        expires = "; expires=" + date.toGMTString();
            }else{
        expires = "";
    }
    document.cookie = name + "=" + value + expires + "; path=/";
}

然后在每个页面中你需要这个会话 ID 你可以读取 cookie，函数如下:

Then in each page you need this session Id you can read the cookie, with a function like:

function readCookie(name) {
    var i, c, ca, nameEQ = name + "=";
    ca = document.cookie.split(';');
    for(i=0;i < ca.length;i++) {
        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 '';
}

读取函数可以在编写它的同一个域的任何页面或选项卡上工作，无论 cookie 是从 javascript 中的页面创建的，还是从服务器创建的.

The read function work from any page or tab of the same domain that has written it, either if the cookie was created from the page in javascript or from the server.

存储id:

var sId = 's234543245';
writeCookie('sessionId', sId, 3);

读取id:

var sId = readCookie('sessionId')
