WordPress中特定的Wp入队脚本

Question

寻找插件时，我遇到了这个website

我看到有一个漂亮的云动画。

因此，我开始在Google上进行搜索以找到代码的来源，并找到了here ... Preview

现在我的问题：

我想在我的本地主机站点上对其进行设置，以便在elementor上对其进行测试。

我将使用html小部件来调用脚本。

我知道的问题是，在 functions.php 中有一个 wp_enqueue_script 选项，脚本在那里..

但是我不明白确切的过程。我 失败 几个小时来设置脚本...

您能告诉我如何集成它吗？我需要一个很好的示例，说明如何使用这些脚本。 一劳永逸地了解如何将脚本集成到wordpress子主题中。

我的设置： 全新安装的空 hello theme和child installed的wordpress。

更新

让我们进一步发展主题 我在做这些操作 functions.php

function my_scripts_method() {
    wp_enqueue_script('custom-script',get_stylesheet_directory_uri() . '/js/ThreeWebGL.js',array( 'jquery' ));
    wp_enqueue_script('custom-script',get_stylesheet_directory_uri() . '/js/ThreeExtras.js',array( 'jquery' ));
    wp_enqueue_script('custom-script',get_stylesheet_directory_uri() . '/js/Detector.js',array( 'jquery' ));
    wp_enqueue_script('custom-script',get_stylesheet_directory_uri() . '/js/RequestAnimationFrame.js',array( 'jquery' ));

}

add_action( 'wp_enqueue_scripts', 'my_scripts_method' );

它似乎可以正常工作。我希望脚本已加载。

我在chrome控制台中只有一条消息：

未捕获的参考错误：未在（索引）：117处定义检测器

我猜是因为我还没有放html吗？

您如何看待snippet？

我用它来创建和添加简码

类似的东西..您认为它安全吗？

事情很快变得很复杂。

我希望有人来告诉我们如何将其集成到wordpress页面中

（具有基本元素是奖励）

Answer 1

出于安全考虑，HTML小部件将删除php标签。但是您有几种选择可以实现您的目标。这是三个：

1. Edit your child theme's functions.php file允许php中的 小部件。 （坏主意）

2. Write your own custom widget可使所需的脚本入队。 （更好的主意）

3. 完全不使用小部件。只需使用Advanced Custom Fields插件将脚本添加到所需页面即可。 （最好的主意恕我直言）

由于您询问了有关加载JS的问题，因此这里是a good resource。
这是关于wp_enqueue_scripts()的另一个话题。

编辑：ACF插件的分步说明：

1. 安装高级自定义字段插件
2. 转到“自定义字段”设置，然后单击“添加新内容”
3. 将字段组命名为“ Javascript设置”
4. 创建规则以限制字段显示在何处以及谁将看到它们
5. 在“样式”旁边，选择“标准”（WP metabox）
6. 点击+添加字段
7. 将其命名为“标题脚本”
8. 将字段类型更改为“文本区域”
9. 将格式更改为“将HTML转换为标签”
10. 从第6步开始重复，但是这次将其称为“页脚脚本”
11. 发布字段组
12. 在header.php中，紧接table.insert( i++, QMap<QString,int> {{iter.key(),iter.value()}} ); 标记之前，添加：</head>
13. 在footer.php中，紧接<?php the_field('header_script'); ?>结束标记之前，添加：</body>
14. 将javascript文件放置在服务器上的文件夹中（最好使用子主题）。
15. 使用常规html <?php the_field(‘footer_script'); ?>标签在页面的新字段中链接javascript

注意：将<script>和header.php文件复制到子主题中，然后在其中进行编辑（步骤12和13），以避免在主题更新时丢失这些更改。
