     Try this. Add onkeyup event on the <textarea> tag then replace event.target to textareaElement to get the value

     var textareaElement = document.getElementById("userName");function updateCount() { document.getElementById("stringLength").innerHTML = textareaElement.value.length;}

     <label for="userName">User name:</label><textarea id="userName" onkeyup="updateCount()" cols="40" rows="3"></textarea><br><p id="stringLength">0</p>

   • Event-Driven Programming Paradigm in Logic Programing

     Top Answer

     Answered Jun 07, 2021 · 1 votes

     Event-driven programming should be similar to how it is done in other languages, you would set up some framework to generate the events and you would call a goal to handle the event, possibly using the system's multithreading facilities (which leads to interesting aspects of transactions on the Prolog database, global vs. thread-local storage etc.)

     Paulo Moura would certainly provide this link to the Logtalk Manual:

   • Event driven vs sequential programming

     Top Answer

     Answered Dec 03, 2009 · 11 votes

     Two different methods to support two different needs. If you have a problem driven by events, then you should use an event-driven methodology. If you need to perform procedures on defined data, but you're not worried about what's happening elsewhere, then obviously you want to use a more "sequential" style.

     Note that typically, these two things are combined. A program's startup, shutdown, and maybe a main processing loop (say, a filter processor in an image app) will be largely sequential, while its UI layer and component interactions are event-driven.

   • Event driven (GUI) programming in C for embedded system

     Top Answer

     Answered Feb 13, 2013 · 1 votes

     The answer would really depend on what platform you are developing for. An embedded RTOS for a Microchip controller is going to have one set of constraints, whereas an RTOS for an ARM solution will be completely different. You should clarify what hardware, or at a minimum, what micro controller, you are designing for.

   What is event based programming?

   • Event-based programming is an incredibly useful paradigm, with use cases ranging from UI in a single-process system to communication between services in large-scale distributed systems. The loosely coupled nature of event-based programming provides many benefits, though it may require a shift in how you think about inter-object communication.

    Nov 8, 2022 · Event-driven programming, or event-oriented programming, is a paradigm where entities (objects, services, and so on) communicate indirectly by sending messages to one another through an intermediary. The messages are typically stored in a queue before being handled by the consumers.
