jquery cookie的用法
jQuery cookie是个很好的cookie插件，大概的使用方法如下
example $.cookie(’name’, ‘value’); 设置cookie的值，把name变量的值设为value example $.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 example $.cookie(’name’, ‘value’); 新建cookie example $.cookie(’name’, null); 删除一个cookievar account= $.cookie('name');取一个cookie(name)值给myvar
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; }};
