I would like to see W3Schools provide an example of a proper login system in their Php example code area.

static int winOrTie() {
   if ( ( ) ) {
      return CROSS;
} else if ( ( ) ) {
      return NOUGHT;
} else if ( ( ) ) {
     return
} else {
     return
}
 
}

This approach can only be used if the board is a fixed size. If you know it is always a 3 x 3 board then it is easy to formulate an if structure. Something simple like this could work...

if(gameboard[0][0] + gameboard[0][1] + gameboard[0][2] == 3*NOUGHT){return NOUGHT;}
if(gameboard[1][0] + gameboard[1][1] + gameboard[1][2] == 3*NOUGHT){return NOUGHT;}
if(gameboard[2][0] + gameboard[2][1] + gameboard[2][2] == 3*NOUGHT){return NOUGHT;}

if(gameboard[0][0] + gameboard[1][0] + gameboard[2][0] == 3*NOUGHT){return NOUGHT;}
if(gameboard[0][1] + gameboard[1][1] + gameboard[2][1] == 3*NOUGHT){return NOUGHT;}
if(gameboard[0][2] + gameboard[1][2] + gameboard[2][2] == 3*NOUGHT){return NOUGHT;}

if(gameboard[0][0] + gameboard[1][1] + gameboard[2][2] == 3*NOUGHT){return NOUGHT;}
if(gameboard[0][2] + gameboard[1][1] + gameboard[2][0] == 3*NOUGHT){return NOUGHT;}

if(gameboard[0][0] + gameboard[0][1] + gameboard[0][2] == 3*CROSS){return CROSS;}
if(gameboard[1][0] + gameboard[1][1] + gameboard[1][2] == 3*CROSS){return CROSS;}
if(gameboard[2][0] + gameboard[2][1] + gameboard[2][2] == 3*CROSS){return CROSS;}

if(gameboard[0][0] + gameboard[1][0] + gameboard[2][0] == 3*CROSS){return CROSS;}
if(gameboard[0][1] + gameboard[1][1] + gameboard[2][1] == 3*CROSS){return CROSS;}
if(gameboard[0][2] + gameboard[1][2] + gameboard[2][2] == 3*CROSS){return CROSS;}

if(gameboard[0][0] + gameboard[1][1] + gameboard[2][2] == 3*CROSS){return CROSS;}
if(gameboard[0][2] + gameboard[1][1] + gameboard[2][0] == 3*CROSS){return CROSS;}

if(turn < 9){
    return INCOMPLETE;
}else{
    return TIE;
}

 

This is a small assignment I have been given. They have given me most of the code and I have to figure out the rest.

 

Given by who? This is terrible code. Don't learn to code like this. There are many books and tutorials available.

Begin with a main() something like this...

public static void main(String[] args)  {

        gameboard = new int[SIZE][SIZE]; // board must be square
        int outcome;
         
        do {
            displayBoard();
            promptUser();
            outcome = winOrTie();
            
        } while ( outcome == INCOMPLETE );
        
        displayResults(outcome);
        
    }// end of main

Main should be simple and provide an outline of what you are doing. In my version of your program it looks like this...

public static void main(String[] args)  {

        gameboard = new int[SIZE][SIZE]; // board must be square
        int turn = 0;
        int outcome;
        displayBoard();
         
        do {
            turn = promptUser(turn);
            displayBoard();
            outcome = winOrTie();
            
        } while ( outcome == -2 );
        
        displayResults(outcome);
        
    }// end of main

This code is almost too horrible to fix. Are you teaching yourself Java?

Do you really want a variable-sized board? That requires a fair amount of additional complexity.

<script>

var items = [];

<?php

$len = count($items);

for ($i=0 ; $i<$len ; $i++) {

    echo 'item[' . $i . '] = "' . $items[$i] . '";';

}

?> 
 

// etc...
 

</script>

I'm not familiar with this. It looks like it will allow an HTTP server to access a Tomcat server?

http://php-java-bridge.sourceforge.net/pjb/index.php

Have you read through this?

http://www.w3schools.com/html/html5_geolocation.asp

http://www.w3schools.com/js/js_ajax_examples.asp

In your above code you have a global var x declared as an element and then later you seem to think it is a string?

The easy fix seems to be just to use float rather than inline-block...

 .summaryBox { 
 float:left;
 width: 20%; 
 height: 250px; 
 margin: 1em 1em 1em 2em; 
 padding: 0; 
 border: 1px solid black; 
 }   
 footer{clear:both;}

You should paste that code into a codeblock...

Hmmm... I see what you are saying. Something odd happens when you put a block inside an inline-block.

The w3Schools tutorial isn't terrible. I just wish it didn't use document.write() and inline javascript. Just rewrite each example so that document.write() isn't used.

http://www.w3schools.com/js/default.asp

One of the first few lessons explains why document.write() is inferior, so then why do they keep using it throughout the rest of the tutorial? I don't know. Also learn to use addEventListener() as a more flexible alternative to inline javascript which is embedded into the HTML.

For books get...

https://www.amazon.com/JavaScript-Definitive-Guide-Activate-Guides-ebook/dp/B004XQX4K0/ref=sr_1_3?ie=UTF8&qid=1485791079&sr=8-3&keywords=javascript&refinements=p_72%3A2661618011

...and either this...

https://www.amazon.com/JavaScript-Good-Parts-Douglas-Crockford/dp/0596517742/ref=sr_1_8?ie=UTF8&qid=1485791079&sr=8-8&keywords=javascript&refinements=p_72%3A2661618011

...or this (they are approximately the same material)...

https://www.amazon.com/JavaScript-Patterns-Better-Applications-Coding/dp/0596806752/ref=sr_1_17?ie=UTF8&qid=1485791342&sr=8-17&keywords=javascript&refinements=p_72%3A2661618011

However please realize that an entirely new and more complex version of Javascript is on the horizon... but you should probably not begin with this book...

https://www.amazon.com/Learning-JavaScript-Essentials-Application-Development/dp/1491914912/ref=sr_1_3?ie=UTF8&qid=1485791459&sr=8-3&keywords=javascript+es6

You could try some open-source code such as...

Have you worked with Php and MySQL?

http://www.w3schools.com/php/default.asp

http://www.w3schools.com/php/php_mysql_intro.asp

You should have zero errors. Your first errors are related to the fact that a meta tag doesn't like a closing slash...

This is good...

<meta http-equiv="Content-Type" content="text/html; charset=utf-8">

This is bad...

<meta http-equiv="Content-Type" content="text/html; charset=utf-8"/>

The internet is filled with tutorials, references, and resources, or you could hire a local web-savvy teenager.

http://www.w3schools.com/

Try fixing the errors in the code...

I need people to enter the info into the system and have it all be searchable and readable by a computer...[...]

Do you realize how absurdly vague that is?

Hmmm... although I bought a book about Javascript promises I have to admit that I have not gotten around to learning much about this topic yet.

Can you expand the example code below so that it describes your situation?

Countdown to what? This looks like quite a mess if all it does is provide a countdown to a specific date/time.

Have you used the browser console to check for errors?

Of course they could use e-mail or a chat application to share answers.

Also--

Do you randomize the order of the questions and the order of the multiple-guess answers for each student? That might make attempts at cheating quite a bit more difficult. Just generate the page content dynamically from a randomized array.

You can see that the example code doesn't do that, so how is your code different?

You want to write event-driven javascript -- i.e. routines that are called as event handlers. See...

https://developer.mozilla.org/en-US/docs/Web/Guide/Events/Media_events

Maybe they simply open another tab and google for each question?

Are you reading the data from a MySQL table? See the example below. You would modify it slightly so that a table is built...
