    <p>I think I know what you mean, I may be wrong.</p> <p>You want to select an image from an array containing strings of HTML which also happens to contain an image tag, you want to use the <code>src</code> attribute value for the background image of your table.</p> <p>You would use a regular expression to do that in a for loop or join the array to a string first, could be used, but as Adam Botley mentioned, store each URL in the array, it will make your life a whole lot easier.</p> <p>It looks like your code is from a tutorial, so if all you really want to do is randomly select a background image for the table that's even easier.</p> <p>Here is what you can do. Create an array of URLs. </p> <pre><code>var urls = ['http://lorempixel.com/200/200', 'http://lorempixel.com/200/200']; </code></pre> <p>Then you need to calculate a random number to use for the key. </p> <pre><code>var index = Math.floor(Math.random() * urls.length); </code></pre> <p>A <a href="https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Math/random" rel="nofollow">random number in Javascript</a> is floating point number between 0 and 1, so you multiply this by the amount of URLs in the array. The <a href="https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Math/floor" rel="nofollow">Math.floor()</a> returns the integer of the argument.</p> <p>Then you'll need a reference to the table element. </p> <pre><code>var theTableElement = document.getElementById('theTableElement'); </code></pre> <p>For that to actually work you must add an id to the table in the HTML. </p> <pre><code>&lt;table id="theTableElement"&gt; &lt;tr&gt; &lt;td&gt;hello&lt;/td&gt; &lt;td&gt;there&lt;/td&gt; &lt;/tr&gt; &lt;tr&gt; &lt;td&gt;you&lt;/td&gt; &lt;td&gt;person :)&lt;/td&gt; &lt;/tr&gt; &lt;/table&gt; </code></pre> <p>Now, to set the background image, you can just. </p> <pre><code>theTableElement.style.background = 'url(' + urls[index] + ')'; </code></pre> <p>Now It should work, let me know!</p>

    1. COI appreciate your answer and the samples. I do not work with JavaScript much, so even the simple stuff is difficult. Ok I tried the code mentioned verbatim and got no result in the background. I even used the document.write(urls[index]); to try and write the img out and it did not work either. I also double checked the string to the images and it does work.

Querying!

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).
