Standard usage of customJS¶
Welcome to the compilation of use cases and examples of how to use customJS to get what you want. If the technical documentation of Omni’s customJS functions was boring, don’t worry, I fell asleep writing it a couple times.
Now we can start having fun (hopefully Type 1 fun) and take a more relaxed look at how to actually use all those commands.
For each of the examples/usages we have also built a sample calculator. This are very simple calculator just to showcase the behaviour. Feel free to copy their code into your calculator or play around with them but DO NOT SAVE ANY CHANGES.
Note
Most of these examples have been taken from the Trello card where we have examples of calculators with customJS.
The standard usages of customJS have been divided in three sections: Basics, Advanced and one section dedicated to advanced uses of value setters. The justification for this last section is that I do what I want value setters are quite complex objects and they can be used in many useful ways, also having a section just for them makes it easy to find stuff around.
If you are looking for unexpected uses of Omni’s customJS functions and hacks to work around the implicit limitations of the current system, then head to From Calculatorian to Calculatorian where we will also teach you ways to write better code and do more by working less 1.
Basics¶
Here we have the examples of the most basic options from customJS that are not just calling the function. As you improve your customJS game you will be coming to this section less and less as you will end up memorising them without trying.
Advanced¶
These are usages of customJS that go further, and effectively create new functionalities. Each function is still used for what it was intended but with some clever tricks we can get new features from them. Some even require usage of strange javascript functions but in general they are just a combination of those used in the Basics section.
