//设置cookie
var setCookie = function (name, value, day) {
//当设置的时间等于0时,不设置expires属性,cookie在浏览器关闭后删除
var expires = day * 24 * 60 * 60 * 1000;
var exp = new Date();
exp.setTime(exp.getTime() + expires);
document.cookie = name + "=" + value + ";expires=" + exp.toUTCString();
};
//删除cookie
var delCookie = function (name) {
setCookie(name, ' ', -1);
};
//传递cookie
function login() {
var name = document.getElementById("userName");
var pass = document.getElementById("passwords");
setCookie('userName',name.value,7)
setCookie('password',pass.value,7);
location.href = 'b.html'
}
function deletecookie() {
delCookie('userName',' ',-1)
}
3. 接受cookie的页面,此处定义为b.html
获取
4. b.html的js代码
//获取cookie代码
var getCookie = function (name) {
var arr;
var reg = new RegExp("(^| )" + name + "=([^;]*)(;|$)");
if (arr = document.cookie.match(reg)){
return arr[2];
}
else
return null;
};
//点击获取按钮之后调用的函数
function getcookie() {
console.log(getCookie("userName"));
console.log(getCookie("password"))
}
二. 通过url传递参数的方式
该案例也是从a.html向b.html页面传递参数
1. a.html的代码
跳转
2.点击跳转按钮可以将input标签的value值传递到b.html
function jump() {
var s = document.getElementsByTagName('input')[0];
location.href='7.获取参数.html?'+'txt=' + encodeURI(s.value);
}
3. b.html中的代码
var loc = location.href;
var n1 = loc.length;
var n2 = loc.indexOf('=');
var txt = decodeURI(loc.substr(n2+1,n1-n2));
var box = document.getElementById('box');
box.innerHTML = txt;
