    <p>Instead of using <code>splice</code> or modifying the original array, why not just store the index of the randomly-selected item into a new array (after making sure it wasn't already selected)?</p> <p>Also, instead of having a container for each image, why not just let them flow one after the other (of course I don't really know what you are ultimately trying to do)?</p> <p>Here is a function that demonstrates this. <a href="http://jsfiddle.net/ErikE/zN93u/" rel="nofollow noreferrer">See this in action in a JS Fiddle</a> or <a href="http://jsfiddle.net/ErikE/zN93u/embedded/result/" rel="nofollow noreferrer">interact with the full-screen result</a>.</p> <p>(My apologies for using jQuery if you don't want to do that; it was simply easier for me to get you a working demo by using a library.)</p> <pre><code>function imageReset() { var selected, img, imageContainer = $('#images').empty(); currentImages = []; while (currentImages.length &lt; 3) { selected = Math.floor(Math.random() * items.length); if (currentImages.indexOf(selected) === -1) { currentImages.push(selected); } } selectedImage = currentImages[Math.floor(Math.random() * 3)]; $('#word').empty().html(items[selectedImage].name); $.each(currentImages, function(i, imageIndex) { img = $('&lt;img&gt;').attr({ src: items[imageIndex].image, width: "200", height: "200" }); if (imageIndex === selectedImage) { img.data('correct', true); } img.appendTo(imageContainer).on('click', imageClick); }); } </code></pre> <p>Here's a preview of what the final page looks like:</p> <p><a href="http://jsfiddle.net/ErikE/zN93u/embedded/result/" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/Cz5lh.png" alt="Image Recognizer JS Fiddle"></a></p> <p>Notes about not using a library:</p> <ul> <li>The trickiest part will be determining if the correct image was clicked on. You can do that using an expando attribute such as "data-correct", but this may be hard to do cross-browser. I used jQuery's data storage, ala <code>data()</code>. You could also, instead of marking the image specially as the selected one, check the 'src' of the image itself and then using this, loop through the <code>currentImages</code> array to find which original item it is and whether it is the right one.</li> <li><code>$.each()</code> loops through an array. You can do fine with <code>for (i = 0, l = arr.length; i &lt; l; i += 1) {}</code>.</li> <li><code>empty()</code> removes all the contents of an element. You can simply delete the first child until there are no children left.</li> <li><code>$('&lt;img&gt;')</code> does the same thing as <code>createElement('img')</code>.</li> </ul> <p>I highly recommend using a library. I cannot see a single reason to avoid one besides "I just want to". You can still learn the plain javascript methods even when using a library, by studying the underlying code. Frankly, if I were a software development business owner, I would <em>require</em> my junior javascript programmers to use the library because the coding speed and quality would be so much higher. They could and maybe should eventually learn how to do it the "old fashioned" way, but in the meantime I would not want them to waste time.</p>

    1. COThank You so much for the great example! I was not planning on using a library but it looks great. I will start work now working out what the code actually does now so it's clear in my mind. Thanks Again!

    2. COYou're welcome. If my code has helped you, would you please use the vote up or "select answer" tools to the left of my answer. Also, please see my (soon) update on some details around avoiding the library. May I ask why you don't want to use a library? It makes your production of a finished product faster, and produces a more reliable solution that works across more browsers.

    3. COI have no problem with libraries, in fact I have used jQuery in my website already. My only issue was I like to know what all the code means. As you have explained it everything makes sense now, thanks a lot.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
