js保存COOKIE，直接給document加上cookie就可以了，但是一般如果單個的加會很麻煩所以一般會直接寫好一個函數，可以直接操作cookie，這樣就很方便了
setCookie這個是寫入cookie，第一個是名稱，第二個是cookie值，第三個是過期時間
getCookie這個是查找cookie;
removeCookie這是你需要刪除的cookie;
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 | function setCookie(name, value, iDay) { var oDate=new Date();
oDate.setDate(oDate.getDate()+iDay);
document.cookie=name+'='+encodeURIComponent(value)+';expires='+oDate; }
function getCookie(name) { var arr=document.cookie.split('; '); var i=0; for(i=0;i<arr.length;i++) { //arr2->['username', 'abc'] var arr2=arr[i].split('=');
if(arr2[0]==name) { var getC = decodeURIComponent(arr2[1]); return getC; } }
return ''; }
function removeCookie(name) { setCookie(name, '1', -1); } |
