無料のテンプレートを使用して、jQuery ベースのマルチギャラリー写真ポートフォリオ サイトをセットアップしました。誰かがページを開いたときに、デフォルトで 3 つのギャラリーのうち最初のギャラリーをロードしようとしています。現在、3 つのギャラリーのいずれかへのリンクのいずれかが押されるまで、何も読み込まれません。以前のユーザーはチュートリアルの作成者に同じことについてのヒントを求めていましたが、次の唯一の答えは次のとおりでした。
$(document).ready(function()
{
$(‘#default’).click()
});
リストに、デフォルトとして開きたいギャラリーのデフォルト ID を追加します。「" yourgalleryname"" コピー/貼り付けする代わりにコードを入力することをお勧めします。これは、スクリプトで異なるコンマがエラーになるためです」 多くの試行錯誤の後、私はライターは、jQuery への一連のコマンドの前に .html にコードを入力させようとしていたという結論に達したので、これを書きました (コードは JavaScript 参照の後、$(function() {.その名前でギャラリーに注意を向けさせるために、デフォルトの「Nature」を入力してみましたが、それは明らかに解決策ではありませんか? 正しい解決策が何であるかについて、私が得ることができる助けをいただければ幸いです.私は認めます.私はコーダーではなく、おそらく簡単な解決策があると思いますが、私は一晩中これに取り組んできましたが、役に立ちませんでした。
<script type="text/javascript" src="js/jquery.easing.1.3.js"></script>
<script type="text/javascript">
$(document).ready(function()
{
$('#default').click()
});
$(function() {
//setting a default page
default: "Nature"
//caching
//the main wrapper of the gallery
var $fp_gallery = $('#fp_gallery')
//the overlay when the large image is displayed
var $fp_overlay = $('#fp_overlay');
ピートの提案に答えて: ピート、あなたの言っていることをもっとよく理解する必要があることは明らかなので、あなたの忍耐に感謝します. 私はあなたの解決策を試しましたが、サイコロはありません。明確にするために: 以前のデフォルト: 自然のことは、理解できない指示に従おうとしたことでした。とにかく、ここに私が修正したコードセクションがあり、あなたの提案に従おうとしています:

$(function() {

Stack Overflow では、チュートリアルを書いた人が書いたコード全体を読み込めません。長すぎるとのことです。セミコロンの欠落に関するあなたのコメントを確認しました。間違いなく修正できますが、ページは正常に読み込まれ、動作しています。許可されている限り、コードは次のとおりです。
