我使用一个免费模板来建立一个基于 jQuery 的多图库照片组合网站。我试图在有人打开页面时默认加载三个画廊中的第一个。现在，在按下三个画廊之一的链接之一之前，什么都不会加载。以前的用户曾向教程作者询问有关同一件事的提示，但唯一得到的答案是：“您可以通过在页面上（缺少单词）之前添加到脚本上的行来添加自动播放：
$(document).ready(function()
{
$(‘#default’).click()
});
并在您的列表中添加您要默认打开的画廊的默认 ID：“”您的画廊名称“”您最好键入代码而不是复制/粘贴，因为不同的逗号会在您的脚本上出现错误“经过多次试验，我来到作者试图让我在对 jQuery 执行一系列命令之前将代码输入 .html 的结论，所以我写了这个（代码在 JavaScript 引用之后和 $(function() { 之前。如您所见，我尝试使用默认值：Nature 以通过该名称将注意力引导到画廊，但这显然不是解决方案？我会很感激我能得到正确解决方案的任何帮助。我承认我我不是编码员，可能有一个简单的解决方案，但我整晚都在努力，但无济于事。在此先感谢您的帮助。
<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');
回答皮特的建议：皮特，很明显我应该更好地理解你在说什么，所以我感谢你的耐心。我试过你的解决方案，但没有骰子。只是要明确一点：默认值：自然之前的事情是我试图遵循我不理解的指示。无论如何，这是我修改的代码部分，试图遵循您的建议：

Stack Overflow 不允许我加载整个代码，这些代码是由编写教程的人编写的。它说它太长了。我确实看到了您对丢失分号的评论，我当然可以修复它，但是页面已经加载并正常运行。这是我允许的尽可能多的代码：
