Mastering Javascript in Acrobat: Passing Values from a Dialog Box to Your PDF

Are you facing challenges while working with a custom dialog box in Adobe Acrobat? If you’re like many developers and learners, you might find issues with passing values correctly from a dialog box to your PDF document. In this guide, we’ll explore a common problem and break it down step-by-step to help you achieve your goal with ease.

The Problem: Passing Data from a Custom Dialog Box

Imagine you want to create a custom dialog box that appears when a button is clicked. This dialog box should collect user input through an editable text field and a list box, and then transfer this input to a text field in the PDF. However, instead of seeing your values appear where they should, they are only showing up in the console and you’re left with "undefined". Frustrating, right?

Let’s delve into the solution!

The Solution: Correcting the Dialog Commit Function

The main issue stems from how we capture and store the values from the dialog. Below is a refined version of the dialog’s commit function that effectively retrieves the values you need.

Step 1: Defining the Dialog Structure

First, ensure that your dialog is structured correctly. Here’s an example setup using JavaScript:

Step 2: Implementing the Commit Function

The commit function is where we accurately capture user input. We need to access the text from the text field alongside the selected value from the list box:

Breakdown of Changes Made:

Storing Values:
Ensure you're correctly storing this.timeEntry and this.techEntry from the dialog inputs.

Accessing List Box Items:
When accessing the list box, iterate through the items and check for positive indices, selecting the corresponding entry.

Conclusion

By following these structured steps, you should now be able to successfully pass user input from your custom dialog box to your PDF fields. Although working with JavaScript in Acrobat can initially seem daunting, understanding how to manage dialog data can significantly enhance your projects.
