jQuery

Eric Sevareid famously said that the chief cause of problems is solutions . The same applies to the HTML trick I blogged about yesterday. As soon as you solve the problem of using HTML directly in your control add-ins, another problem arises: what do you do with actual images your control add-in includes?

In my previous post , I’ve written about the situation when you (or somebody you trust) redeclares the $ variable, thus inadvertently breaking all your jQuery code. I’ve also explained how to remedy for it inside the code you write by applying the Immediately Invoked Function Expression (IIFE) or Self-Executing Anonymous Function pattern.

First, a disclaimer. This post is written for (C/)AL developers who are struggling with JavaScript, who copy and paste JavaScript code from Stack Overflow right into VS Code and are happy when it works, and confused when it doesn’t.

One of major limitations of control add-ins is not being able to define HTML. It seems so unbelievably unbelievable, that anyone looking at it from the outside of the NAV/BC playground may say “obviously, you must be missing something!”. But I am not.
