JXA Resources

Revised: 2019-11-28 16:16 GMT-6

This is a list of the key resources I have found useful. If you know of others, please post in a comment below, and I will add to this list.

I have tried to order this list in the order that, to me, is best for learning JXA from scratch. We all learn a bit diferently, so adjust to suit your style/needs. Please post if you have suggestions on learning JXA.

// Click an OS X app sub-menu item
// 2nd argument is an array of arbitrary length (exact menu item labels, giving full path)

// e.g. menuItemClick("InqScribe", ['View', 'Aspect Ratio', 'Use Media Ratio'])

// Note that the menu path (spelling & sequence) must be exactly as in the app
// See menuItemTestClick() below for a slower version which reports any errors

// For OS X 10.10 Yosemite JXA JavaScript for Automation

I find list slices good for this:

>>> x = [1, 2, 3]
>>> a = x [1:2]
>>> a
[2]
>>> b = x [4:5]
>>> b
[]

How to Scroll a Page With JavaScript

Copied from: How to Scroll the Page With JavaScript Link

This page demonstrates how to use the JavaScript scrollBy and setTimeout methods to make a web page scroll down automatically. Change the timeout value to alter the scrolling speed in milliseconds. The example function below (arbitrarily called pageScroll) shows how this can work:

function pageScroll() {
    	window.scrollBy(0,50); // horizontal and vertical scroll increments
 scrolldelay = setTimeout('pageScroll()',100); // scrolls every 100 milliseconds

function sleep(ms) {
  return new Promise(resolve => setTimeout(resolve, ms));
}

async function demo() {
  console.log('Taking a break...');
  await sleep(2000);
 console.log('Two seconds later, showing sleep in a loop...');
