私はどちらかを知りたいです：a。 jQueryを使って選択した後でクッキーを使って背景画像を保存する方法、これに先立ってjQueryを使用する方法を詳しく解説する方法、またはb。どのようにそれのためのクッキーを設定するために、通常のjavascriptを使用するには、私はすでに場所にプロンプ​​トやテキストのためのクッキーを持っているが、画像はあまりにも複雑になっている。どんな助けでも大歓迎です！誰かが私にこの答えを与えることができます：

<script> 
 
    //alert(document.cookie); 
 
    function setCookie(cname, cvalue, exdays) { 
 
    var d = new Date(); 
 
    d.setTime(d.getTime() + (exdays * 24 * 60 * 60 * 1000)); 
 
    var expires = "expires=" + d.toGMTString(); 
 
    document.cookie = cname + "=" + cvalue + "; " + expires; 
 
    } 
 

 
function getCookie(cname) { 
 
    var name = cname + "="; 
 
    var ca = document.cookie.split(';'); 
 
    for (var i = 0; i < ca.length; i++) { 
 
    var c = ca[i]; 
 
    while (c.charAt(0) == ' ') { 
 
     c = c.substring(1); 
 
    } 
 
    if (c.indexOf(name) == 0) { 
 
     return c.substring(name.length, c.length); 
 
    } 
 
    }

あなたが意味する場合は、クッキーがないだろう、後で、その後の検索のためにユーザーのブラウザに画像を保存する、「背景画像を保存」すること。ドメインあたりのCookieの最大サイズは4093 bytesです。あなたが代わりに行うことができるのは、画像のURLやファイル名のような画像への参照を保存することだけです。後でそのユーザーの選択を判断するのに使用できます。

イメージをユーザーのブラウザに保存することをお勧めする場合は、代わりにlocalStorageを使用してください。 How to save an image to localStorage and display it on the next page?をチェックアウトして、その方法を知ることができます。 localStorageの最大サイズは10mbです。
