Question details
User needs a complex fillable PDF form with JavaScript validations and calculations to function properly after being processed through Adobe Sign.
- Product
- Adobe Sign
- Device & OS
- not provided
- Scenario
- Sending a complex fillable PDF form containing JavaScript rules for signature via Adobe Sign.
- Observed behavior
- JavaScript-based calculations, validation rules, required field constraints, and repeated data fail to execute once the form is uploaded and sent through Adobe Sign.
Verify if your PDF form relies heavily on Acrobat-specific desktop JavaScript and create a backup of your original fillable document before attempting any conversions or web uploads.
Complete Form Validations in Acrobat Desktop Before Uploading
Since Adobe Sign removes JavaScript execution, fill out the dynamic portions of the form locally to lock in calculated values before routing it for signatures.
Adobe Sign does not execute standard Acrobat JavaScript in the web environment for security and compatibility reasons. This means any dynamic behavior built into the desktop PDF will fail during the signing process.
Launch the original fillable PDF form in a desktop PDF viewer that supports JavaScript execution.
Input all necessary data that relies on calculations, conditional formatting, or strict field validations.
Print the document to PDF or save a static copy so that the calculated values and populated fields are permanently locked into the document.
Import this static, pre-filled document into Adobe Sign solely for the purpose of adding signature fields and routing it to the signers.
Redesign Form Rules Using Adobe Sign Native Fields
If users must input data and trigger calculations during the signing process, rebuild the logic using Adobe Sign's native web calculation tools instead of Acrobat JavaScript.
Fill, Manage, and Sign PDF Forms Seamlessly in WPS Office
Avoid compatibility issues by managing your PDF forms locally. WPS Office provides comprehensive desktop PDF tools to fill interactive forms, save data securely, and apply digital signatures without relying on web converters that strip formatting.
- 1. Download and Open: Launch WPS Office and navigate to the dedicated PDF tools workspace.
- 2. Open Your Form: Open your interactive PDF form directly from your local computer drive.
- 3. Fill Out Data: Click into the fields to input your data; the desktop client will retain standard form structures.
- 4. Sign the Document: Use the 'Sign' feature under the 'Fill & Sign' tab to create and insert your digital signature.
- 5. Save and Share: Save the finalized document as a standard PDF to share with others safely.
Frequently Asked Questions
Does Adobe Sign convert my fillable PDF to a static image?
No, Adobe Sign does not convert the document into an image. However, it does strip out or neutralize Acrobat JavaScript for security and web rendering compatibility. This makes the form behave as if the dynamic fields are disabled.
Can I use JavaScript for form calculations in Adobe Sign?
No, Adobe Sign does not support standard Acrobat desktop JavaScript for calculations. You must rebuild calculations using Adobe Sign's native calculated fields and syntax within its web authoring tool.
Why are my required fields being ignored after uploading to Adobe Sign?
Validation rules, including 'required field' constraints configured via Acrobat desktop, are removed during the Adobe Sign upload process. You must manually mark fields as required directly within the Adobe Sign web interface.
