使Cookie在一小时内到期 [英] Make a cookie expire in one hour

问题描述

  function createCookie（）名称，值，天）{
 if（days）{
 var date = new Date（）; 
 date.setTime（date.getTime（）+（days * 60 * 1000））; 
 var expires =; expires =+ date.toGMTString（）; 
} 
 else var expires =; 
 document.cookie = name +=+ value + expires +; path = /; 
} 
 
函数readCookie（name）{
 var nameEQ = name +=; 
 var ca = document.cookie.split（';'）; 
 for（var i = 0; 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; 
} 
 
 sWhere =http://google.com; 
 
 if（！readCookie（'viewcheck'））{
 createCookie（'viewcheck'，1,1）; 
} else {
 window.location = sWhere; 
} 
  

如何让Cookie在一小时内过期？

解决方案

您的函数使用的是一个天 ，而不是从 60 * 1000 开始的60秒（以毫秒为单位）。
你应该将该参数重命名为 minutes ，然后你可以很容易地看到你只需要乘以60的小时数。

I have some code for a cookie that i want to make expire in 1 hour the code is:

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

    sWhere = "http://google.com";

    if(!readCookie('viewcheck')){
    createCookie('viewcheck',1,1);
    } else {
    window.location = sWhere;
    }

How can i make the cookie expire in an hour?

解决方案

Your function is using a days argument that is only changing minutes, not days since 60*1000 is 60 seconds in milliseconds. You should rename that argument to minutes, and then you can easily see that you just need to multiply the numberof hours by 60.
