我有一个wordpress网站，我需要将一些javascript移动到页脚。我使用的主题（photocrati）只在header.php文件中使用wp_enqueue_scripts标签共4次。
我要做的是找到一种方法，希望动态地将javascript文件移动到页脚。我意识到使用$ in_footer会更容易使用enqueue_scripts正确引用它们，但是唉，事实并非如此。
由于这是一个摄影工作室网站，我需要尽我所能来减少加载时间。现在，显然我不打算像谷歌页面速度建议那样将CSS移动到页脚，因为我不希望在访问者第一次查看时我的网站被无格式化。
在完成其他所有工作之后（我显然无法做任何关于最小化或设置利用浏览器缓存不在我的网站上托管的文件，即google analytics js文件），页面速度见解建议，“删除渲染 - 阻止JavaScript和CSS在上面的内容“是我剩下的。我希望一旦我将js移动到页脚，我的页面加载时间将在5秒以下，考虑到它现在只有不到6，并且有19个脚本资源。
希望有人可以通过添加到functions.php文件中的一些PHP代码为我提供一些指导，因为我（大多数情况下）在编写时了解PHP代码的用途。但是，我很难解读头文件中发生的事情，并且能够找到所有19个js文件以从头文件中删除它们并正确地将它们排队。
EDIT 这是header.php文件。我注意到有些脚本甚至没有以任何方式在这里调用，因为当我搜索文件说“hoverintent.js”时，它无处可寻，但如果我在页面加载后搜索源代码，当然它在标题中。

header.php文件中包含js文件引用的部分。正如我之前所说，并非所有这些都是通过header.php文件调用的。

排队脚本有第五个参数，它是一个布尔值，默认为false。如果设置为true，则脚本将位于页脚中。如果您的主题在页脚中有wp_footer()方法。
<?php wp_enqueue_script( $handle, $src, $deps, $ver, $in_footer ); ?>
一个例子：
<?php wp_enqueue_script( 'mysript', get_template_directory_uri() . '/js/myscript.js', array(), false, true ); ?>
