Adobe Javascript

Files can be automated within Adobe software with scripts.

Currently, I am using Adobe Acrobat Pro v.11, which supports really old js

How to run Javascript

1. create or select an element.
2. Add/Edit js.
3. paste desired js into it, press OK.
4. switch to selection mode and click the element to execute.

Javascript support:

• no let, use var
• no console.log
• no template literals, concatenate strings with +
• pages are 0-indexed in js, but 1-index everywhere else

I recommend writing modern JS and using a transpiler (like Babel) to convert to ES5 and below.

Automatically create bookmark TOC

original js

// Get the root of the bookmark tree
var myRoot = this.bookmarkRoot;

for (let i = 0; i <= 42; i++) {
  console.log(i, 4 + 2*i );
  // Create a new bookmark under the root
  myRoot.createChild(`Lesson ${i}`, `this.pageNum = ${4 + 2*i};`); 
  // Create a child bookmark under the first bookmark
  var firstBookmark = myRoot.children[i];
  firstBookmark.createChild("Particle", `this.pageNum = ${4 + 2*i};`);
  firstBookmark.createChild("Particle", `this.pageNum = ${4 + 2*i};`);
  firstBookmark.createChild("Particle", `this.pageNum = ${4 + 2*i};`);
}

supported js

// Get the root of the bookmark tree
var myRoot = this.bookmarkRoot;
var firstBookmark = myRoot[0];
// for (var i = 0; i <= 42; i++) {
for (var i = 42; i >= 0; i--) {
  // Create a new bookmark under the root
  var val = 3 + 2 * i;
  myRoot.createChild("Lesson " + i, "this.pageNum = " + val + ";");
  
  // Create a child bookmark under the first bookmark
  firstBookmark = myRoot.children[0];
  firstBookmark.createChild("Particle", "this.pageNum = " + val + ";");
  firstBookmark.createChild("Particle", "this.pageNum = " + val + ";");
  firstBookmark.createChild("Particle", "this.pageNum = " + val + ";");
}
