复制代码
代码如下:
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(); // use expires attribute, max-age is not supported by IE } 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 { // only name given, get cookie 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]); // Does this cookie string begin with the name we want? if (cookie.substring(0, name.length + 1) == (name + '=')) { cookieValue = decodeURIComponent(cookie.substring(name.length + 1)); break; } } } return cookieValue; } }; function getcookie(name) { var cookie_start = document.cookie.indexOf(name); var cookie_end = document.cookie.indexOf(";", cookie_start); return cookie_start == -1 ? '' : unescape(document.cookie.substring(cookie_start + name.length + 1, (cookie_end > cookie_start ? cookie_end : document.cookie.length))); } function setcookie(cookieName, cookieValue, seconds, path, domain, secure) { var expires = new Date(); expires.setTime(expires.getTime() + seconds); document.cookie = escape(cookieName) + '=' + escape(cookieValue) + (expires ? '; expires=' + expires.toGMTString() : '') + (path ? '; path=' + path : '/') + (domain ? '; domain=' + domain : '') + (secure ? '; secure' : ''); }
使用方法： 提供方便方法操作cookie :
复制代码
