本文实例讲述了jQuery操作cookie的插件。分享给大家供大家参考,具体如下:
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; } };
调用也很方便:
//使用方法如下: //设置cookie的键值对 //$.cookie('name', ‘value'); //设置cookie的键值对,有效期,路径,域,安全 //$.cookie('name', ‘value', {expires: 7, path: ‘/', domain: ‘jquery.com', secure: true}); //新建一个cookie 包括有效期 路径 域名等 //读取cookie的值 //var account= $.cookie('name'); //删除一个cookie //example $.cookie('name', null);
希望本文所述对大家jQuery程序设计有所帮助。
