我怎麼可以運行addcookies功能運行PHP函數（）來保存自己的餅乾...謝謝你的價值！如何在JavaScript

function addcookies(value) { 
$pid = $_POST['pid']; 
$expiry = time() + 60 * 60 * 24 * 30; 

// Update the number of items 
if(isset($_COOKIE['count'])) 
$count = $_COOKIE['count']; 
else 
$count = 0; 

// Put the item into shopping cart 
$key = "item: ".$count; 
setcookie($key, $pid, $expiry); 
setcookie("count", $count+1, $expiry); 
}

所有的

XXXXXXXXXXXXXXXXXXXXX什麼??? – 2014-11-21 17:51:49

@RileyTse你知道危害PHP運行在服務器和客戶端的JavaScript上，對不對？（哦，你可能想通過驗證程序來運行你的HTML，。湖中有不少錯誤） – Biffen 2014-11-21 17:54:17

是....其實我只是想保存的cookies – RileyTse 2014-11-21 18:06:03

首先，你的HTML代碼是不正確的。您oppened body標籤兩次，你的標題標籤是出了頭部件，它甚至不是和在體內。

由於比夫說，在評論，你不能在頁面加載後運行PHP。相反，你可以使用Ajax。 Ajax Documentation

你必須創建裏面你的PHP代碼的文件，然後無需重新加載頁面使用Ajax執行它。當我看到你寫的評論：「把項目放入購物車。」購物車中的物品不要存放在，都不是，也不是瀏覽器會話cookie。使用您的數據庫，而不是因爲數據存儲在任何cookie或會議將是脆弱的。
