How to Fix Reset Form Not Clearing Required Fields in Acrobat PDF
Question details
The user is experiencing an issue where resetting a PDF form does not revert the required status of a field that was changed dynamically via a checkbox script.
- Product
- Adobe Acrobat
- Device & OS
- not provided
- Scenario
- Developing or filling out a dynamic PDF form with interactive elements and JavaScript actions.
- Observed behavior
- The standard Reset Form action clears the field input values but leaves altered properties, such as the required status of a calendar field, unchanged.
Ensure you have access to the PDF form's underlying JavaScript settings or calculation scripts in Adobe Acrobat's Prepare Form mode.
Use Calculation Script for Dynamic Required State
Move the required-state logic directly to the target field's calculation script so it automatically evaluates based on the checkbox's value upon reset.
A standard 'Reset Form' action only reverts fields to their default input values; it does not reset field properties like visibility or required status. Modifying the required status via JavaScript is permanent unless a script actively changes it back.
Launch your document in Acrobat and enter the 'Prepare Form' mode from the tools menu.
Right-click the field that needs the dynamic required state (such as the calendar field) and select 'Properties'.
Navigate to the 'Calculate' tab, select 'Custom calculation script', and click 'Edit'.
Input the script: event.target.required = (this.getField("Check Box1").value != "Off"); ensuring you replace 'Check Box1' with the actual name of your checkbox field.
Click 'OK' to save the properties. When the form resets, the checkbox will revert to its default state, and the calculation script will instantly update the required status accordingly.
Create a Custom Reset Button with Additional Scripts
Build a completely custom Reset button that executes both the standard input reset and specific property resets simultaneously.

Frequently Asked Questions
Why doesn't the Reset Form button clear field visibility or required states?
The standard Reset Form action only reverts the input values of fields to their default state (such as clearing typed text). It does not execute scripts or revert field properties like 'required' or 'hidden', which are treated as permanent until actively modified by another script.
Can I set a default required state for a PDF form field?
PDF form fields do not have a built-in 'default' required state that can be automatically reverted to via standard reset tools. If a property is modified by JavaScript during the session, it remains in that modified state until explicitly scripted back.
Is it better to use calculation scripts or validation scripts for changing field properties?
For properties that depend on other fields (like a required status depending on a checkbox selection), it is highly recommended to use a calculation script on the target field. This guarantees the property evaluates and updates automatically whenever the dependent field changes or resets.
How do I correctly test my custom reset button in Acrobat?
Switch your workspace from 'Prepare Form' mode to 'Preview' mode. Fill in some test data, trigger the checkboxes to change the required status dynamically, and then click your custom reset button to verify that both the data clears and the required status successfully reverts.
