Programmatic APIs — JZ and JUSTZIX

What the in-page helper API is

Every JavaScript snippet in a JustZix rule — and the code behind every action button — runs in a context where two ready-made globals are waiting for you: window.JZ and window.JUSTZIX. Nothing to import, nothing to load; they are available from the first line of your script.

This is a deliberately small API. Instead of hundreds of methods it gives you two solid anchor points: one to drive action buttons, one to log. Everything else you do with the page's plain JavaScript.

JZ — driving action buttons

The JZ object connects your code to the extension's action buttons. The key methods are:

• JZ.click('LBL') — programmatically clicks the action button labelled "LBL".
• JZ.action('LBL') — returns the button's DOM element, so you can style it or inspect its attributes.
• JZ.actions() — an array of all visible action buttons.
• JZ.labels() — an array of the original labels with their casing preserved.

Label lookup is case-insensitive — JZ.click('btn') and JZ.click('BTN') hit the same button.

JUSTZIX — logging to the Output Console

The JUSTZIX object is a logger that writes straight into the extension's Output Console window. It offers JUSTZIX.log(), .warn(), .error(), .info() and .debug() — each appends an entry at the matching level. The aliases __JUSTZIX__ and JZ.log are also at hand.

That means you can trace what a rule is doing without opening DevTools. Messages land in one calm place, separate from the noise of the browser console.

Why a stable API beats hand-rolled DOM glue

You could query for buttons by selector and dispatch your own events, but that code breaks the moment the extension's layout shifts. JZ and JUSTZIX give you a steady contract: the same method name works no matter how the internals change.

Pair it with a mutation observer and you have a real workflow — a rule waits for an element, clicks a series of actions and reports the outcome:

// Action "AUTO" — chain three other actions
JZ.click('LOAD');
setTimeout(() => JZ.click('PROC'), 500);
setTimeout(() => { JZ.click('SAVE'); JUSTZIX.info('done'); }, 1500);
