js点击checkbox存入cookie自动登录(个人菜鸟笔记)

html:

<input type = "checkbox" id = "remember">

js:

if(document.getElementById("remember").checked){   //如果自动登录的checkbox被勾上

                        var exp = new Date();

//cookie的保存时间

                        exp.setTime(exp.getTime() + (30*24*60*60*1000));

//保存cookie的name、value

                        document.cookie = "name=" + escape(document.getElementById("userName").value) + "; expires=" + exp.toGMTString()+";path=/";  

                        document.cookie = "pw=" + escape(document.getElementById("password").value) + "; expires=" + exp.toGMTString()+";path=/";
                }

//取出cookie的值

var arr = document.cookie.match(new RegExp("(^| )"+"name"+"=([^;]*)(;|$)"));

        if(arr != null) return unescape(arr[2]); return null;
