javascript 设置cookie

function getCookie(key){var cookieValue = document.cookie;var cookieValueArr = cookieValue.split(';');var getKey = function (cookieValueArr, k){if(!cookieValueArr || cookieValueArr.length <= 0){return null;}else{var ckv = cookieValueArr.shift();var ckvArr = ckv.split('=');ckv1 = ckvArr[0].trim();ckv2 = ckvArr[1].trim();if(ckv1 == k){return ckv2;}else{return getKey(cookieValueArr, k);}}}var t_cookie = getKey(cookieValueArr, key);if(t_cookie){var temp_cookie = unescape(t_cookie);temp_cookie = JSON.parse(temp_cookie);return temp_cookie;}else{return t_cookie;}}//设置cookie, 有效时间为秒function setCookie(key, value, seconds, path){var expires;if(!(key && value)){return ;}if(seconds){var date = new Date();date.setTime(date.getTime() + (seconds * 1000));expires = "; expires=" + date.toGMTString();}else{expires = "";}var toString = function(str){var string = JSON.stringify(str);return string;}document.cookie = key + "=" + escape(toString(value)) + expires + "; path=/";}function deleteCookie(key){setCookie(key, '', -36000);}
