如何将自定义 javascript 添加到 WordPress 管理员? [英] How to add custom javascript to WordPress Admin?

问题描述

我想向编辑帖子"页面添加一些自定义 jquery 代码，这非常简单，例如在有人按下发布"时显示一个 div.

I want to add some custom jquery code to the Edit Post page, something really simple like showing a div when someone presses Publish.

唯一的限制是我想通过使用插件来实现这一点，而不是破解管理模板文件.

The only restriction is that I want to achieve this through the use of a plugin, not hacking the admin template files.

我尝试使用一些操作来回显一些脚本标签，但似乎不是这样.

I've tried echoing some script tags using some actions but it doesn't seem to be the way.

推荐答案

使用 admin_enqueue_scripts 操作和 wp_enqueue_script 方法将自定义脚本添加到管理界面.

Use the admin_enqueue_scripts action and the wp_enqueue_script method to add custom scripts to the admin interface.

这假设您的插件文件夹中有 myscript.js.相应地改变.my_custom_script 句柄对于您的模块和脚本应该是唯一的.

This assumes that you have myscript.js in your plugin folder. Change accordingly. The my_custom_script handle should be unique for your module and script.

function my_enqueue($hook) {
    // Only add to the edit.php admin page.
    // See WP docs.
    if ('edit.php' !== $hook) {
        return;
    }
    wp_enqueue_script('my_custom_script', plugin_dir_url(__FILE__) . '/myscript.js');
}

add_action('admin_enqueue_scripts', 'my_enqueue');
