Descripció
A minimal way to inject a single inline JavaScript snippet into the <head> of one or more specific posts, pages or products. You give it a comma-separated list of post IDs and the JS body — that is the entire surface area.
The point is the absence of features. There is no per-post UI, no script library, no CDN selector, no “fire on event” toggle. If all you need is to drop a tracking pixel or a tiny script on three specific pages, you do not want a 2 MB plugin that wants to manage your whole site.
Set it up under Settings Lightweight JS snippet. The page provides a textarea for the JS (no <script> tags — those are added for you) and a comma-separated list of post IDs to load it on.
Captures
Settings page with code editor and post-ID list.
Instal·lació
- Upload
/lightweight-js-snippet/to the/wp-content/plugins/directory. - Activate the plugin through the Plugins menu in WordPress.
- Go to Settings Lightweight JS snippet and paste in your JS plus the post IDs.
PMF
-
Where does the script run?
-
It is printed inline in the
<head>of the listed posts/pages, only. -
No — they are added for you. Only paste the JS body.
-
Does it support more than one page?
-
Yes. Use a comma-separated list of post IDs. Search for the post name in the settings page to find the ID automatically.

1.4.1
- Fix empty
<script id="jhljs-script">tag rendered on every page when no snippet was configured. Logic error (||where&&was meant) plus no early-return on empty options. - Fix Settings link on the Plugins screen — previous filter targeted the wrong plugin basename, and the URL pointed at a non-existent menu slug. Both corrected.
1.4
- Settings page now lets you pick target posts/pages by typing their title — the “comma-separated post IDs” textbox is replaced with a chip-style picker. Two small REST endpoints (
jhljs/v1/posts,jhljs/v1/search) gated tomanage_optionspower the lookup and search.
1.3
- Sanitize the post-id list and the JS snippet on save via
register_setting()callbacks (digits/commas/whitespace for the IDs,wp_kses'data'for the script — same filter that was already applied on output). - Escape every translated string in the settings UI (
_e()/__()esc_html_e()/esc_html__()) and useesc_textarea()for the snippet field. - Add the missing
License,License URIandText Domainheaders, fix the text-domain mismatches, and add an explicit version towp_enqueue_script(). - Bumped minimum PHP to 7.4. Tested up to WordPress 6.9.
1.2
- Bugfix when escaping script.
1.1
- Code editor added.
- Support for multiple ids.
- Securing plugin.
1.0
- Initial release.
