如何通过特定键设置和获取cookie？ [英] How to set and get cookie by perticular keys?

问题描述

如果我通过'loggedinUser'设置cookie

if I set cookie by 'loggedinUser'

document.cookie="loggedinUser=dawood"; 

那么如何获得这个特定的'loggedInUser'cookie值？

then how to get this perticular 'loggedInUser' cookie value?

推荐答案

function getCookie(name)
  {
    var re = new RegExp(name + "=([^;]+)");
    var value = re.exec(document.cookie);
    return (value != null) ? unescape(value[1]) : null;
  }

                        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;
                    }
