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:
<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:
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; } };
