在Javascript响应中设置会话变量

标签: javascript php session response

我想知道是否有办法在Ajax响应中设置会话变量,基本上看起来像这样:

// this is response
function(response)
{
<?php $_SESSION['ID'] = response.id ?>
// or something similar to this? 
}

然后我需要使用会话以便我可以访问它。

// (Some php file)

$var_id = $_SESSION['ID']; 

这可行吗?

以下是设置,获取和删除Cookie的三个功能

function setCookie(cname, cvalue, exdays) {
    var d = new Date();
    d.setTime(d.getTime() + (exdays*24*60*60*1000));
    var expires = "expires="+ d.toUTCString();
    document.cookie = cname + "=" + cvalue + "; " + expires;
}
function getCookie(cname) {
    var name = cname + "=";
    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);
        }
        if (c.indexOf(name) == 0) {
            return c.substring(name.length,c.length);
        }
    }
    return "";
}
function deleteCookie(cname){
  document.cookie = cname+"=; expires=Thu, 01 Jan 1970 00:00:00 UTC";
}

您可以使用HTML5 sessionStorage对象在本地保存数据,但是对于单个会话。当用户关闭特定浏览器选项卡时,将删除数据。

sessionStorage.id = response.id ;
