Question details

- Product
- Adobe Acrobat
- Device & OS
- not provided
- Scenario
- Automating PDF button actions across multiple files using Action Wizard and JavaScript.
- Observed behavior
- The user needs to use the correct method (setAction) to assign a specific script to a button event, such as MouseUp, instead of using addScript.
Ensure you have Adobe Acrobat Pro installed, as the Action Wizard feature and advanced batch JavaScript editing capabilities are not available in standard or free PDF readers.
Use the setAction Method in Action Wizard
Apply the setAction method within your Action Wizard script to dynamically assign JavaScript code to form buttons across multiple PDF files.
When assigning an action to a specific button event (like a mouse click) via batch processing, you should use the setAction method. This is different from addScript, which is used for injecting document-level functions.
In Adobe Acrobat Pro, go to the Tools menu and select 'Action Wizard'. Click 'New Action' to start creating your batch process.
Under the 'More Tools' section on the left sidebar, select 'Execute JavaScript' and click the '+' icon to add it to your action steps. Uncheck 'Prompt user' to allow the batch process to run automatically.
Click 'Specify Settings' and input your JavaScript code. Use the format: this.getField("Button1").setAction("MouseUp", "app.alert('Hello!', 3);");
Replace "Button1" with the actual name of your target button field. The first argument ("MouseUp") dictates the trigger event, and the second argument is the script string that will execute when the button is clicked.
Save your action, giving it a recognizable name. Click on the action in the Action Wizard list, add the folder or files you want to process, and click 'Start' to apply the button actions to all selected PDFs.

Frequently Asked Questions
What is the difference between setAction and addScript in Acrobat JavaScript?
The setAction method attaches a specific JavaScript string to run when a defined event (like a MouseUp click) occurs on a field. In contrast, addScript is used to inject document-level JavaScript functions that load when the PDF is opened and can be called from anywhere in the document.
Why isn't my setAction script triggering when I click the button?
Ensure that your first argument is explicitly set to "MouseUp" rather than "MouseDown" or "Click". In PDF JavaScript, "MouseUp" is the standard trigger for button clicks. Additionally, verify that the field name you provided exactly matches the name of the button in the PDF properties.
Can I use setAction to clear all form fields in a PDF?
Yes, you can use setAction to attach a reset script. For example, using this.getField("ResetBtn").setAction("MouseUp", "this.resetForm();"); will clear the form fields whenever the user clicks the designated 'ResetBtn' button.
Is the Action Wizard available in free PDF readers?
No, Action Wizard and automated batch processing capabilities are advanced tools generally reserved for premium software versions, such as Adobe Acrobat Pro.
