Brain Teaser Game using jQuery

In this article you will learn how to develop interactive web pages, applications and games using jQuery scripting, HTML 5 and CSS3.

Before starting the tutorial you should know some jQuery history and its features. In order to work with jQuery, you should be aware of the basics of JavaScript, HTML, and CSS.

Chapter 1

jQuery


jQuery is not a language, it is well-written JavaScript code. jQuery is a cross-platform JavaScript library designed to simplify the client-side scripting of HTML. jQuery is a fast and concise JavaScript Library created by John Resig in 2006 and it was released in January 2006 at BarCamp NYC.

jQuery core features:

  • Ajax support
  • Animations
  • Cross-browser support
  • DOM manipulation
  • Event handling
  • Lightweight

jQuery advantages:

  • Improve the performance of the application
  • Develop most browser compatible web page
  • Fast and extensible
  • UI integrity

Downloading

The jQuery scripting file can be downloaded from the jQuery Official website.

Chapter 2

In this chapter I will show you how to create an interactive game using jQuery, HTML 5 and CSS3 step-by-step. It consists of the following three major parts.

  1. Creating HTML elements
  2. Styling with CSS
  3. Scripting with jQuery

The following figures define the main index page:

The Figure 2 defines the Brain Teaser game process.

Part 1: HTML

Before I start this tutorial, I assume that you are familiar with HTML, CSS and jQuery. I also assume that you understand what jQuery is and how to use it in your pages.

Use basic HTML code to create the HTML elements. The following is the HTML code I used for this tutorial.

  1. <!DOCTYPE html>  
  2. <html lang="en">  
  3.   
  4. <head>  
  5.     <meta charset="utf-8">  
  6. </head>  
  7.   
  8. <body>  
  9.     <form>  
  10.         <img src="Images/bulb_mind_brain_svg-256.png" alt="hi" style="width:256px;height:256px;">  
  11.         <br>  
  12.         <br>  
  13.         <h1>SCORE</h1>  
  14.         <h1><div id="output">00</div></h1>  
  15.         <p>Choose your number</p>  
  16.         <select id="dropDownId">  
  17.             <option value="1">1</option>  
  18.             <option value="2">2</option>

The preceding HTML code defines the entire page design. Use a different HTML tag to create the entire page design. It contains three major processes. The first process uses a SELECT tag to create a drop down list with data. The second process uses an INPUT tag to create buttons and the third process is an IMG tag to link with the image destination path.

Part 2: CSS

Now I am moving to the second part. The second part process defines CSS code to make the look and feel for all the HTML elements as we used before in the HTML part. The following is the CSS code I have used in this tutorial.
  1. <style type="text/css">  
  2.     html {  
  3.         text-aligncenter;  
  4.     }  
  5.       
  6.     body {  
  7.         background-color: Aquamarine;  
  8.     }  
  9.       
  10.     select {  
  11.         padding3px;  
  12.         margin0;  
  13.         -webkit-border-radius: 4px;  
  14.         -moz-border-radius: 4px;  
  15.         border-radius: 4px;  
  16.         -webkit-box-shadow: 0 3px 0 #ccc0 -1px #fff inset;  
  17.         -moz-box-shadow: 0 3px 0 #ccc0 -1px #fff inset;  
  18.         box-shadow: 0 3px 0 #ccc0 -1px #fff inset;  
  19.         background#f8f8f8;  
  20.         color#888;  
  21.         bordernone;  
  22.         outlinenone;  
  23.         display: inline-block;  
  24.         -webkit-appearance: none;  
  25.         -moz-appearance: none;  
  26.         appearance: none;  
  27.         cursorpointer;  
  28.     }  
  29.       
  30.     @media screen and (-webkit-min-device-pixel-ratio:0) {  
  31.         select {  
  32.             padding-right18px  
  33.         }  
  34.     }  
  35.       
  36.     Label {  
  37.         positionrelative  
  38.     }

Before adding the CSS code be sure it cover the entire browser display area. The preceding CSS code defines the entire HTML element design process.

Part 3

Now I am moving to the third part. This is the final important jQuery scripting code, it makes the HTML element functionalities, effects and animations. The following is the jQuery scripting code I have used in this tutorial.

The first step in the jQuery scripting part is to include the required jQuery library reference in the head element of your page.
  1. <script src="http://code.jquery.com/jquery-1.10.2.js"></script>  
The following is the complete jQuery and JavaScript code I used in this tutorial.
  1. <script src="http://code.jquery.com/jquery-1.10.2.js"></script>  
  2. <script src="http://code.jquery.com/ui/1.10.4/jquery-ui.js"></script>  
  3. <script type="text/javascript">  
  4.     $(document).ready(function() {  
  5.         var seconds;  
  6.         $("#btnShowSimple").click(function(e) {  
  7.             $("#output").html("00");  
  8.   
  9.             function countdown() {  
  10.                 seconds = 60;  
  11.   
  12.                 function tick() {  
  13.                     var counter = document.getElementById('countdown');  
  14.                     seconds--;  
  15.                     counter.innerHTML = "0:" + (seconds < 10 ? "0" : "") + String(seconds);  
  16.                     if (seconds > 0) {  
  17.                         setTimeout(tick, 1000);  
  18.                     } else {  
  19.                         alert("Game over");  
  20.                         HideDialog();  
  21.                     }  
  22.                 }  
  23.                 tick();  
  24.             }  
  25.             countdown();

  36.                     counter.innerHTML = "0:" + (seconds < 10 ? "0" : "") + String(seconds);  
  37.                     if (seconds > 0) {  
  38.                         setTimeout(tick, 1000);  
  39.                     } else {  
  40.                         alert("Game over");  
  41.                         HideDialog();  
  42.                     }  
  43.                 }  
  44.                 tick();  
  45.             }  
  46.             countdown();  
  47.             ShowDialog(true);

  57.             location.reload();  
  58.             e.preventDefault();  
  59.         });  
  60.         $("#shuffle div").hover(function() {  
  61.             $(this).css('cursor''pointer');  
  62.   
  63.         }, function() {  
  64.             $(this).css('cursor''auto');  
  65.         });  
  66.         $("#shuffle div").click(function(e) {  
  67.             var select = $('#dropDownId :selected').text();  
  68.             var Original = ($(this).attr("id"));  
  69.             var parent = $("#shuffle");  
  70.             var divs = parent.children();  
  71.             var Count = 0;  
  72.             if (Original == select) {  
  73.                 $('#output').html(function(i, val) {  
  74.                     return val * 1 + 1  
  75.                 });  
  76.             }  
  77.             while (divs.length) {  
  78.                 parent.append(divs.splice(Math.floor(Math.random() * divs.length), 1)[0]);  
  79.   
  80.             }  
  81.         });  
  82.     });  
  83.   
  84.     function ShowDialog(modal) {  
  85.         $("#overlay").show();  
  86.         $("#dialog").fadeIn(300);  
  87.         if (modal) {  
  88.             $("#overlay").unbind("click");  
  89.         } else {  
  90.             $("#overlay").click(function(e) {  
  91.                 HideDialog();  
  92.             });  
  93.         }  
  94.     }  
  95.   
  96.     function HideDialog() {  
  97.         $("#overlay").hide();  
  98.         $("#dialog").fadeOut(300);  
  99.     }  
  100. </script>  
The preceding jQuery scripting code improves the performance of the application and it defines the entire HTML element UI functionality and effects.
