    copied!<p>I am loading and echoing data from an XML file through the <code>$xml=simplexml_load_file</code> function. Everything is working perfectly, the code is as follows ( in part ):</p> <pre><code>&lt;?php $xml=simplexml_load_file('testfeed1.xml'); $max = 12; $i = 1; foreach($xml-&gt;someTag as $feed){ if ($i &lt;= $max){ echo "&lt;span class='previewImage' name='{$feed-&gt;some-subTag}' style='background:url({$feed-&gt;imageTag}) no-repeat center;'&gt;"; $i++; } } ?&gt; </code></pre> <p>In this example, I am drawing a URL from a tag in the XML and placing it at the background for a given span, all the images in the array (if that is the right usage of the word) appear without any problems.</p> <p>What I would very much like to figure out is how to make the background in this short example change base upon an <code>onBlur</code> function set in a form field which is also on the page.</p> <p>So if I have the following code:</p> <pre><code>Image URL: &lt;input type='text' name='smallImage' id='someId' value='{$feed-&gt;imageTag}' /&gt; </code></pre> <p>As you can see the field is pre-loaded with the "imageTag" from the XML here as well.</p> <p>What syntax or function could I use to change the backgroud of the span above after a new URL has been written. I was under the presumption that the <code>onBlur</code> function would be the best. </p> <pre><code>&lt;input type='text' name='smallImage' id='someId' value='{$feed-&gt;smallImage}' onblur="document.find(.imagePreview#{$feed-&gt;some-subTag}).setAttribute("background", .smallImage.someId.value);" /&gt; </code></pre> <p>Again, I am complettely new to js and php.</p> <p>Thanks in advance for any tips, hints or tricks.</p> <p>/Brian</p>
