保存用戶選擇的背景圖片在JavaScript中使用Cookie跨網頁

好吧，所以我想使用cookie保存此功能，而且我似乎無法獲取與該功能交互的Cookie。保存用戶選擇的背景圖片在JavaScript中使用Cookie跨網頁

var backImage = new Array(); 

backImage[0] = "dotPattern.png"; 
backImage[1] = "stripesPattern.png"; 
backImage[2] = "boxPattern.png"; 
backImage[3] = ""; 

function changeBGImage(whichImage){ 
    document.body.background = backImage[whichImage]; 

}

你能不能讓我知道我做錯了或我必須做什麼。我已將圖像文件和html全部放在同一個文件夾中。讓我知道你是否需要別的東西，我也可以把它放在這裏。

非常感謝您對

但你在哪裏使用cookies？在這裏我看不到任何這樣的東西。 – dds 2014-10-20 05:06:23

@dds嘿我只是把頁面的意思是要植入的cookie來改變背景顏色 – Jane 2014-10-20 05:46:53

要使用您需要保存的cookies和負載他們明確。您可以在this問題中找到如何在javascript中執行此操作。
