    copied!<p><em>(Incorrect answer removed.)</em></p> <hr> <p>Edit:</p> <p>Initially, I misinterpreted the <code>jquery.js</code> as a file you created, rather than the real jquery. After testing out the code, I can see that the data that you are sending may be the problem. Can you post a sample with the data for <code>$result_cameras[$i]["camera_hash"]</code>, <code>$result_cameras[$i]["camera_name"]</code>,<code>$camera_quality_flash</code>, and <code>$id_hash</code>? Also, what is the value for <code>url</code> that results?</p> <hr> <p>Solution:</p> <p>The button submits the form, and the page is reloading. The dialog shows, but then the page is immediately reloaded, so it seems like there never was a dialog. In order to prevent this behavior, the button's <code>click()</code> function has to return <strong>false</strong> (if no value is return, it is treated as a <strong>true</strong> result). </p> <p>Notes on this solution:</p> <ol> <li>Relies on the objects being in existence, so I moved everything inside a <code>ready()</code> event. </li> <li>Assumes this one of many buttons inside a loop (because of the <code>$i</code> variable in the PHP code), so the data is in the attributes of the button. </li> <li>Since there may be several buttons with the same functionality, it is generalized for multiples. </li> <li>The jQuery load command (cf., <a href="http://api.jquery.com/load/">http://api.jquery.com/load/</a> ) takes 3 paramenters: <ul> <li>the url</li> <li>some data</li> <li>a callback function for when the load returns (if you only provide 2 parameters, the second one is assumed to be the callback function). The callback parameters are: <ul> <li><em>responseText</em>, the HTML returned from the server</li> <li><em>textStatus</em>, a status message</li> <li><em>XMLHttpRequest</em>, the request interface, which can be used to see various info about the request (cf., <a href="http://www.w3.org/TR/XMLHttpRequest/">http://www.w3.org/TR/XMLHttpRequest/</a>)</li> </ul></li> </ul></li> </ol> <p>The HTML test file:</p> <pre><code>&lt;html&gt; &lt;head&gt; &lt;script language="javascript" type="text/javascript" src="https://ajax.googleapis.com/ajax/libs/jquery/1.7.1/jquery.js"&gt;&lt;/script&gt; &lt;script language="javascript" type="text/javascript" src="https://ajax.googleapis.com/ajax/libs/jqueryui/1.8.16/jquery-ui.js"&gt;&lt;/script&gt; &lt;/head&gt; &lt;body&gt; &lt;form&gt; &lt;?php $i = 0; $result_cameras = array(array("camera_hash" =&gt; "test1", "camera_name" =&gt; "test2")); $camera_quality_flash = 1; $id_hash = "hashish"; echo '&lt;button id="monitor1" class="monitor" camHash="' . $result_cameras[$i]["camera_hash"] . '" camName="' . $result_cameras[$i]["camera_name"] . '" camQual="' . $camera_quality_flash . '" &gt;Monitor 1&lt;/button&gt;'; echo '&lt;button id="monitor2" class="monitor" camHash="' . $result_cameras[$i]["camera_hash"] . '-2" camName="' . $result_cameras[$i]["camera_name"] . '-2" camQual="' . $camera_quality_flash . '-2" &gt;Monitor 2&lt;/button&gt;'; ?&gt; &lt;div class="tester"&gt;TEST DIV&lt;/div&gt; &lt;/form&gt; &lt;/body&gt; &lt;script type="text/javascript"&gt; var js = jQuery.noConflict(); js(document).ready(function(){ var monitor = js(".monitor"); //alert(monitor[1]); monitor.each( function(i){ js(this).click( function(){ //alert(js(this).attr('camHash')); startMonitor( js(this).attr('camHash'), js(this).attr('camName'), js(this).attr('camQual') ); return false; } ); } ); var startMonitor = function(cameraHash, cameraName, cameraFlashQuality) { var url = [ 'flash/app.php?user=&lt;?php echo $id_hash; ?&gt;', 'camera=' + cameraHash, 'name=' + encodeURIComponent(cameraName), 'quality=' + cameraFlashQuality ].join('&amp;'); js('&lt;div&gt;TEST DIV 2&lt;/div&gt;').load(url , function(response, status, xhr) { js('.tester').text( "&lt;div&gt;xhr: &lt;br /&gt;" + xhr.status + "&lt;br /&gt;" + xhr.statusText + "&lt;br /&gt;" + xhr.getAllResponseHeaders() + "&lt;br /&gt;" + xhr.responseText + "&lt;br /&gt;" + xhr.responseXML + "&lt;br /&gt;" + "&lt;/div&gt;" ); // js(this).dialog(); } ); }; }); &lt;/script&gt; &lt;/html&gt; </code></pre>
