Navigating to different note for use in plugins - command?

JosPolfliet · 2020-10-25T15:47:32.515Z

I'm trying to write a plugin that will show all incoming links to a Note. The excellent existing search function makes this very easy. My code as adapted from the TOC example:

import joplin from 'api';

function formatLink(note: any) {
	return `<li>
		<a class="incoming-item-link" href="#" data-slug="${note.id}">${note.title}</a>
	</li>
	`
}

joplin.plugins.register({

	onStart: async function () {
		// Create the panel object
		const panel = await joplin.views.panels.create();
		await joplin.views.panels.addScript(panel, './webview.js'); // Add the JS file
		await joplin.views.panels.setHtml(panel, 'Loading...');

		async function updateIncomingLinks() {
			const note = await joplin.workspace.selectedNote();

			if (note) {
				const searchResults = await joplin.data.get(['search'], { query: `/${note.id}`, type: "note", fields: ["title", "id"] });
				var incomingListHTML = [];

				for (const note of searchResults) {
					incomingListHTML.push(formatLink(note))
				}

				await joplin.views.panels.setHtml(panel, `
						<div class="container">
							Incoming links for note id ${note.id}
							<br>
							Incoming:
							<ul>
							${incomingListHTML.join('\n')}
							</ul>
							with length ${incomingListHTML.length}.
						</div>
					`);
			} else {
				await joplin.views.panels.setHtml(panel, 'Please select a note to view the incoming links.');
			}
		}

		await joplin.workspace.onNoteSelectionChange(() => {
			updateIncomingLinks();
		});

		await joplin.views.panels.onMessage(panel, (message) => {
			if (message.name === 'scrolltoNote') {
				// STUCK HERE
				joplin.commands.execute('scrollToHash', message.hash)

			}
		});

		// Also update the TOC when the plugin starts
		updateIncomingLinks();
	},

});

And in webview.js

document.addEventListener('click', event => {
    const element = event.target;
    if (element.className === 'incoming-item-link') {
        // Post the message and slug info back to the plugin:
        webviewApi.postMessage({
            name: 'scrolltoNote',
            hash: element.dataset.slug,
        });
    }
});

Looking through the Joplin Commands I can't seem to find the relevant command to trigger. Does that command exist? Can I somehow dispatch the NAV_GO property from within the message handler?

Apologies if this is a very noob React/Electron/Node thing that I missed. Don't usually develop in this language but want to help extend Joplin with useful plugins for myself and too share with the community.

That's a good question and indeed it seems there's currently no way from a plugin to jump to a particular note, which is an oversight. I'll add this for the next release.
