1、設定cookie(名稱,值,過期時間)
function setCookie(key,value,d){ if(d === undefined){ document.cookie = encodeURIComponent(key) + "=" + encodeURIComponent(value); }else{ document.cookie = encodeURIComponent(key) + "=" + encodeURIComponent(value) + ";max-age=" + (d*60*60*24); } }
2、查詢cookie(名稱)
function getCookie(key){ var arr1 = document.cookie.split("; "); for(var i = 0; i < arr1.length; i++){ var arr2 = arr1[i].split("="); if(arr2[0] == key){ return decodeURIComponent(arr2[1]); } } }
