Mystery Master | View a Logic Puzzle in JavaScript | Member |
|---|
This article explains how to view a logic grid puzzle in the JavaScript programming language. If you have not already done so, please read my article "Model a Logic Puzzle in JavaScript". This article will focus on the logic puzzle "Five Houses". Please look at this logic puzzle before continuing. You should have a basic knowledge of JavaScript, know some of the newer constructs, and understand how classes work in JavaScript.
One of the main concerns of any application is to have a responsive User Interface (UI).
If the UI is unresponsive, the user will think the application has stopped working.
A C# application can get around this problem by using the async/await keywords.
Until these keywords are common in JavaScript, I use the following two technologies:
(1) the setTimeout keyword, and
(2) Web Workers.
The setTimeout keyword is discussed towards the end of this article.
Web Workers will be discussed in a future article. The component that manages the UI is called the Viewer.
The Viewer component is the UI manager for Mystery Master. Because this is is a web application, it must manage HTML, CSS, and JavaScript. Some of this is done using PHP. For instance, I use PHP to display common headers and footers for most of my pages. But the two most important visual components for solving a logic puzzle are the dashboard (aka Board), and the tabbed-interface (aka Tabby). These two components are displayed on the logic puzzle page after the text.
Note: Given everything I've said so far, I should probably take a look at React.

The forms for the nouns, verbs, links, facts, and rules are shown in my article "Model a Logic Puzzle in JavaScript". The forms for the marks, chart, and grids will be discussed in a future article. So that means the Stats form and the Setup form are discussed in this article.
The Statistics form displays information about how the puzzle was solved. It tells you how many marks and pairs were entered by level, law, and rule. Here are the statistics after our example puzzle has been solved.
import { Mark } from "../puzzle/Mark.js";

The Setup form displays options for the user that control how the application solves a logic puzzle. Here is what setup looks like when there is no puzzle.
|
Pauses
AllLevel Solution Violation Mark Trigger Guess Placer |
General
AutorunRechart Rules Triggers |
Levels
AllLevel 1 Level 2 Level 3 Level 4 |
Laws
AllLaw 1 Law 2 Law 3 Law 4 Law 5 |
The Setup form is initially displayed via the setup.php file.

The Locker module is a wrapper for HTML 5 Storage.

The Former module contains helpful methods that return HTML as a string.
For example, these methods are called to populate most of the forms in the tabbed-interface component.

Here is an interesting article concerning setTimeout.
To wit, JavaScript has a concurrency model based on an "event loop", and calling setTimeout adds a message to the queue.
This technique avoids the dreaded "a script is taking too long to run" dialog.
Using setTimeout has its consequences - it turns a procedure-based program
into an event-driven one.
If the UI could be updated every time a mark was entered, this would not be a problem.
But there is one thing we must take into account - the user may want the program to pause for certain events, like when a mark is entered.
If we say that each event places one or more tasks into a queue, we need a method that can process each task in order.
Below is a simplified version of the doTasks method found in the Viewer class.
function doTasks() {
if (numTasks === maxTasks) return;
let data = tasks[numTasks++];
// Perform the task based on the key.
switch (data.key) {
}
// Exit if the pause flag is true. Call resumeTasks when the Resume button is pressed.
if (pauseFlag) {
board.pauseWork();
return;
}
// Recursively call doTasks via setTimeout.
setTimeout(function () { doTasks(); }, ms);
}
Sharp-minded people will notice this is similar to the Producer-Consumer problem. After the consumer performs a task, it must see if it needs to wait. If the consumer does not need to wait, it simply moves on to the next task in the queue. But if the consumer needs to wait, instead of spinning CPU cycles in a loop until the user presses the Resume button, the consumer simply stops running. This is the Not Runnable state. Now the only way for the consumer to resume is to have the click event of the Resume button tell the consumer to "wake up" and put the consumer into the Runnable state. I'm probably mixing metaphors here, but you get the idea.
The user may request the program to pause in the situations given below.
Here are all of the possible states for the Work and Quit buttons. Note that a button's caption may change for a specific state. For simplicity, the following refers to a button by its current caption.
Warning: For DOM objects with an id, most browsers will auto-create JavaScript variables with the id as its name! I don't like this because I do not want the viewer to access fields that are managed by subcomponents.
I hope you enjoyed reading this article. My motivation for writing this article is that you will try to model a logic puzzle on your own. Then together we can find better ways to model and/or solve logic puzzles. Thank you.
