    <p>I'm not sure what your specific problem is, but there are certainly a number of things that you could do to improve the overall design.</p> <p>Firstly, are you sure that this is even something that you want to do in Javascript? It seems like you are modifying a text file on your server to tell your pages which ads to serve. That's alright, but if you have the option, it would be better to do this server side. Just include the appropriate urls to the images before you send the HTML back to the users browser using PHP or a similar language if you have access to do so. This removes complexity from your code, improves page load speed, and properly displays your ads even without proper Javascript support.</p> <p>If you are going to do this with AJAX, then I would highly recommend using JSON formatted data and some type of library to handle the request for you. Parsing text files presents a number of problems, and formatting data as JSON gives you a cheap way to convert it to a Javascript object. jQuery is one popular choice for doing this: <a href="http://api.jquery.com/jQuery.getJSON/" rel="nofollow">http://api.jquery.com/jQuery.getJSON/</a></p> <p>You could format your file more like:</p> <pre><code>{ "img": "http://myhost/img/mm.jpg" "link": "http://myhost/" "width": "192" "height": "108" } </code></pre> <p>Then you would need to do something like this to update the image field on your page:</p> <pre><code>$.getJSON("test.js", function(json) { $.each(json, function(key, value) { //parse the keys and values appropriately in here }); }); </code></pre> <p>You also probably don't want to use document.write. This overwrites the entire content of the page. You probably want to select your image element in some way and then change its attributes. You can use jQuery selectors for this. See the section on manipulation for ways to modify the img element once you've selected it.</p> <p><a href="http://api.jquery.com/category/selectors/" rel="nofollow">http://api.jquery.com/category/selectors/</a></p> <p><a href="http://api.jquery.com/category/manipulation/" rel="nofollow">http://api.jquery.com/category/manipulation/</a></p>

    1. COThanks for the reply. I want to be able to load the image info from an external file, possible even on an external site. I probably could do that in PHP, but I don't know how to do that... And I don't know much AJAX/jQuery, so I'm not sure how I would do that.. Any suggestions are welcome though ;)

    2. COYou're using AJAX already. Your using XMLHttpRequest() to request data asynchronously. I suggested jQuery simply because I thought it would be easier.

    3. COI'd love to use jQuery, but I don't know how to get things with that, and it's now working with AJAX (I meant that I don't know much AJAX, I just pieced things together from snippets I found online). If someone would be willing to give me the code to get it working with jQuery, I'd use that, but I don't know enough to get working...

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).
