使用JavaScript在HTML页面中处理会话 [英] Session handling in HTML page using JavaScript

问题描述

我们可以在javascript的帮助下在HTML页面中进行会话处理吗？

如果是，如何？如果没有，为什么？

解决方案

javascript仅支持cookie。您可以将它们设置为跟踪用户会话，但不支持使用会话。

 函数createCookie（name ，值，天）{
 var expires =; 
 if（days）{
 var date = new Date（）; 
 date.setTime（date.getTime（）+（days * 24 * 60 * 60 * 1000））; 
 expires =; expires =+ date.toGMTString（）; 
} 
 document.cookie = name +=+ value + expires +; path = /; 
} 
 
函数readCookie（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）; 
} 
} 
返回null; 
} 
 
 function eraseCookie（name）{
 createCookie（name，， -  1）; 
}

Can we do session handling in HTML page with the help of javascript?

If yes, how? If not, why?

解决方案

javascript only support cookies. You can set them up to keep track of a user session but they do not support the use of sessions.

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

function readCookie(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 eraseCookie(name) {
    createCookie(name,"",-1);
}
