JQuery居然没有操作cookie相关的函数,搜了下官方有个cookie的插件。
简单使用方法:
- <html>
- <head>
- <title>JQuery-Cookie插件</title>
- <script type="text/javascript" src="jquery-1.4.js"></script>
- <script type="text/javascript" src="jquery.cookie.js"></script>
- </head>
- <body>
- <a href="#">设置cookie1</a><br>
- <a href="#">设置cookie2</a><br>
- <a href="#">获取cookie</a><br>
- <a href="#">删除cookie</a><br>
- </body>
- </html>
- <script type="text/javascript">
- $(function(){
- var COOKIE_NAME = 'test_cookie';
- //设置cookie,通过时间间隔
- $('a').eq(0).click(function() {
- $.cookie(COOKIE_NAME, 'test', { path: '/', expires: 1 });
- return false;
- });
- // 设置cookie,到期时间
- $('a').eq(1).click(function() {
- var date = new Date();
- date.setTime(date.getTime() + (1 * 24 * 60 * 60 * 1000));
- $.cookie(COOKIE_NAME, 'test', { path: '/', expires: date });
- return false;
- });
- // 获取 cookie
- $('a').eq(2).click(function() {
- alert($.cookie(COOKIE_NAME));
- return false;
- });
- // 删除cookie
- $('a').eq(3).click(function() {
- $.cookie(COOKIE_NAME, null, { path: '/' });
- return false;
- });
- });
- </script>
插件的源代码也很简单:
原文地址:http://www.aspxcs.net/HTML/0114192819.html
- jQuery.cookie = function(name, value, options) {
- if (typeof value != 'undefined') { // name and value given, set cookie
- options = options || {};
- if (value === null) {
- value = '';
- options.expires = -1;
- }
- var expires = '';
- if (options.expires && (typeof options.expires == 'number' || options.expires.toUTCString)) {
- var date;
- if (typeof options.expires == 'number') {
- date = new Date();
- date.setTime(date.getTime() + (options.expires * 24 * 60 * 60 * 1000));
- } else {
- date = options.expires;
- }
- expires = '; expires=' + date.toUTCString();
- }
- var path = options.path ? '; path=' + (options.path) : '';
- var domain = options.domain ? '; domain=' + (options.domain) : '';
- var secure = options.secure ? '; secure' : '';
- document.cookie = [name, '=', encodeURIComponent(value), expires, path, domain, secure].join('');
- } else {
- var cookieValue = null;
- if (document.cookie && document.cookie != '') {
- var cookies = document.cookie.split(';');
- for (var i = 0; i < cookies.length; i++) {
- var cookie = jQuery.trim(cookies[i]);
- if (cookie.substring(0, name.length + 1) == (name + '=')) {
- cookieValue = decodeURIComponent(cookie.substring(name.length + 1));
- break;
- }
- }
- }
- return cookieValue;
- }
- };
