本文实例分析了jquery读写cookie操作。分享给大家供大家参考,具体如下:
jquery cookie需要脚本文件如下:
jQuery.cookie = function(name, value, options) { if (typeof value != \'undefined\') { options = options || {}; if (value === null) { value = \'\'; options = $.extend({}, options); 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; } };
页面调用只要引进这个文件
$.cookie(\"name\"); //根据cookie名字取到cookie值 $.cookie(\"name\", \"value\");//设置cookie 名字,值 $.cookie(\"name\", value, { expires: 7 }); //设置cookie 名字,值,生命周期等属性 $.cookie(\"name\", null); //根据cookie名移除cookie
希望本文所述对大家jQuery程序设计有所帮助。
