Laserfiche Form Tools

Personal toolkit for working with Laserfiche modern Forms inline JavaScript — capture/replay test data, accumulated API quirks, and per-form source backups.

What this solves

You have a form that you need to test many times. Maybe it triggers a workflow and/or a document merge rule and you're tired of entering test data into the form to make downstream tweaks.

Modern Laserfiche Forms have no built-in way to save test data. Filling out a 30-field form by hand every time you tweak a script is painful. This repo provides:

• Capture/inject snippets to record current form values as JSON and replay them on page load
• API quirks documentation — the not-obvious sandbox behaviors that took real time to figure out
• Per-form source backups — version-controlled copies of each form's inline JS

tl;dr No Dev Tools Super Quick Start

1. Paste capture-via-field.js at the bottom of your form's inline JS.
2. If your form already has an onFormSubmission handler, comment it out temporarily.
3. Save the form. Open it, fill out fields with your desired test values.
4. Click Submit. Submission is blocked, and the bridge field on the page now contains pretty-printed JSON of every other field's value.
5. Copy that JSON out of the bridge field. Save it to forms/<form-name>/test-data.json for safekeeping.
6. Remove the capture snippet from inline JS, restore the original onFormSubmission.

Quick start

1. Capture test data from a manually-filled form:

   • Paste snippets/capture.js at the bottom of your form's inline JS
   • Save, fill out the form, click Submit
   • Copy the JSON from the browser console
   • Save to forms/<form-name>/test-data.json

2. Inject on reload:

   • Paste snippets/inject.js at the bottom of your inline JS
   • Replace the TEST_DATA placeholder with your captured JSON
   • Reload the form — fields auto-populate

3. Toggle off for production by flipping INJECT_TEST_DATA = false.
