我添加了jQuery函数＆＃34; Backstretch＆＃34;到我的博客，但我只希望它适用于主页。 我尝试将每个单独页面的背景设置为黑色图像，但黑色只是淡入幻灯片。
您建议使用哪种方法将幻灯片限制在主页上？ （请记住，我刚刚开始使用此代码......）
以下是代码：
<script src='http://ajax.googleapis.com/ajax/libs/jquery/1.10.2/jquery.min.js' type='text/javascript'/>

答案 0 :(得分：0)
在以下条件中包含模板中存在的jQuery Backstretch插件代码 -
<b:if cond='data:blog.url == data:blog.homepageUrl'>
<!-- jQuery Backstretch plugin code -->
</b:if>
此条件只会加载主页上的代码。
在您的博客中，最终代码将如下所示 -
<b:if cond='data:blog.url == data:blog.homepageUrl'>
