web前端学习之js操作获取和设置cookie

web前端培训核心技术如何使用js操作获取和设置cookie

//创建cookie

function setCookie(name, value, expires, path, domain, secure) {

    var cookieText = encodeURIComponent(name) + ‘=’ + encodeURIComponent(value);

    if (expires instanceof Date) {

        cookieText += ‘; expires=’ + expires;

    }

    if (path) {

        cookieText += ‘; expires=’ + expires;

    }

    if (domain) {

        cookieText += ‘; domain=’ + domain;

    }

    if (secure) {

        cookieText += ‘; secure’;

    }

    document.cookie = cookieText;

}




//获取cookie

function getCookie(name) {

    var cookieName = encodeURIComponent(name) + ‘=’;

    var cookieStart = document.cookie.indexOf(cookieName);

    var cookieValue = null;

    if (cookieStart > -1) {

        var cookieEnd = document.cookie.indexOf(‘;’, cookieStart);

        if (cookieEnd == -1) {

            cookieEnd = document.cookie.length;

        }
