Probably you are looking for JavaScript™ for Acrobat® API Reference. This reference should be the most complete. But, as @Orbling said, not. Adobe has enhanced JavaScript so that you can easily integrate this level of interactivity into your PDF documents. ronaldweinland.info and ronaldweinland.info shows the detailed information about Acrobat JavaScript Scripting. This function can create document-level JavaScript actions that. JavaScript is a lightweight, interpreted programming language. Audience.

Also, some functionality in these files will not operate in a browser- it is usually best to save the files, then open them in Acrobat or Adobe Reader. Fill list entries from pasted text list This helper PDF makes it easy to load entries into a drop list on the PDF form you are building by simply copying and pasting the text from an Excel file, or any text source. After loading the list, you just copy the dropdown field from this form onto your form.

In this case, the output of the function is a Document Object.

Objects are converted to text by simply converting their type information to a string. The result shown in Figure 7 tells us the type of object created. This result is only useful in letting us know the function worked. If app. Both of these situations would have been displayed in the Console Window.

Since the current document was just created with app. The advantage to using the Console Window is to make this information available to copy to the system clipboard for use with another script in Acrobat or for something else.

The Acrobat JavaScript Console (Your best friend for developing Acrobat JavaScript)

Using the Console to display status and error messages Besides testing code, the Console Window has one other important role in debugging JavaScript.

It is the standard location for displaying status and error messages. The Acrobat JavaScript environment has a built-in error handling system. When something goes wrong, this error-handling system usually displays some helpful message sometimes in the Console Window, so this is the first place to look when things aren't working. In addition, you can create your own status and error messages to display here. As an example, let's execute something that will cause an error. Enter and run the following line of code in the Console Window: app.

Acrobat responds by generating an error, which is displayed by the Console Window, shown in Figure 8. This message is critical to understanding why the code failed, especially if the function call is buried in several lines of code inside another script. Always check the Console Window first when something goes wrong. Note that the second message on the line indicates a security error. For our purposes, this is an erroneous and unhelpful message.

There was no real security error, and while it may then seem that Adobe is deliberately trying to either terrify or confuse us, there is a reason the message is being displayed. In fact, the message is not related to the JavaScript engine at all. It is the result of the Acrobat security model, which was made much more robust in versions 9, X, and XI by adding a security layer.

This layer blocks operations that don't fit with Acrobat's sense of rightness.

JavaScript operations or errors that relate to external resources on the web or local file system tend to spook this security layer, which then throws out miscellaneous security errors. If you work with Acrobat JavaScript for any length of time, you'll find all sorts of operations that have nothing to do with security, but nonetheless generate security errors.

We can also create our own messages for display in the Console Window. This object provides a few functions for manipulating and accessing the Console Window, but for our purposes here the console. This function displays a single line of text on the next available line in the Console Window. The following line of code displays the words "Hello Acrobat.

Just place a few console. It is up to the developer to decide what information to display.

This information should be relevant to the state of the script. For example, the following line helps us understand how JavaScript events work in Acrobat.

The code can be placed in any script location in a PDF file. More information about those can be found in the manual. Browsers usually only focus on continuous output. One of the most important of such features are the Description objects.

These objects describe a rectangle which represents layout positions and dimensions of a given document object. Description objects are explored in detail in the PDFreactor manual. There are various types of converted objects, such as converted, BoxDescription and LineDescription representing a single page, box or line, respectively.

With these objects, you can access layout information during runtime.

PDFKit is a PDF document generation library for Node and the browser that makes creating complex, multi-page, printable documents easy. The API embraces chainability, and includes both low level functions as well as abstractions for higher level functionality.
