Laserfiche Version 11 Forms Layout Designer

Updated January 20

asked on January 20

I've been using Laserfiche 11's Modern Designer, and I've been trying to get better by learning JavaScript through a simple question and answer process. Unfortunately, I've run into needing to weed out JS code that was used in previous versions of LF because it doesn't work in the newer version of LF.

Does anyone have any resources on how to use JavaScript with LF 11 Modern Designer? I'm looking to do a back to basics approach that explains objects, properties, terminology, etc.

I've got experience in object oriented programming in Visual Basic and C++, but I'd like to learn about how to use JavaScript in the Laserfiche environment.

Thanks,

Scott

This is a good place to start: The LFForm Object

There are several posts on Answers as well where users have broken down the coding. There a few videos in Aspire as well that walk through JS in the new designer and some solutions in the Marketplace.

Aspire is the best place to find JS courses from previous empowers. If you are able to come to Empower this year I'd highly recommend it as well.

I am putting together a CSS/JS best practice guide for the form designer right now. It should help the documentation AI chatbot weed out classic vs form designer scripts. In the meantime I would

Learn a little about promises to handle asynchronous methods from the LFForm object
Skim through the LFForm Object to learn about the various methods available
All fields support HTML in their labels/text above/text below if you want to do any HTML customizations outside of a typical custom html field
Make sure to use try/catch branches in your code so you don't break forms saving to the repository
