    copied!<p>I am dynamically including a javascript file into a html page, which works fine. But when I run the function 'tryData' from the file the variables return as undefined. I've been looking for hours can't find a similar problem anywhere, does anyone know what the problem is?</p> <p>function in external file:</p> <pre><code>function tryData(id, size){ document.getElementById('content').innerHTML = '&lt;iframe src="http://domain.com/feeds/'+id+'/'+size+'/" id="frame"&gt;&lt;/iframe&gt;'; if(window.data){ clearInterval(timer); data(); } } </code></pre> <p>the line I am using to call it:</p> <pre><code>tryData(131, 'large'); </code></pre> <p>I know that the function is running because the frame is inserted as expected, but there's no content as the URL for the frame reads 'domain.com/feeds/undefined/undefined/', instead of 'domain.com/feeds/131/large/'.</p> <p>Thanks in advance for any help :)</p> <hr> <p>Here is an example of a html page with the function:</p> <pre><code>&lt;!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"&gt; &lt;html xmlns="http://www.w3.org/1999/xhtml"&gt; &lt;head&gt; &lt;meta name="robots" content="NOINDEX,NOFOLLOW" /&gt; &lt;meta http-equiv="Content-Type" content="text/html; charset=utf-8" /&gt; &lt;title&gt;Untitled Document&lt;/title&gt; &lt;/head&gt; &lt;body&gt; &lt;!-- Widget --&gt; &lt;div id="content"&gt;&lt;/div&gt; &lt;script&gt; (function(d, s) { var js = d.createElement(s), ins = d.getElementsByTagName(s)[0]; js.src = "http://domain.com/feeds/insert.js"; ins.parentNode.insertBefore(js, ins); tryData(131, 'large'); }(document, 'script')); &lt;/script&gt; &lt;!-- Widget End --&gt; &lt;/body&gt; &lt;/html&gt; </code></pre> <p>here is the js file:</p> <pre><code>function data(){ var u; u = document.URL; $.post("http://domain.com/data.php", { u: u} ); } function tryData(id, size){ document.getElementById('lsb').innerHTML = '&lt;iframe src="http://domain.com/feeds/'+id+'/'+size+'/" id="frame"&gt;&lt;/iframe&gt;'; if(window.data){ clearInterval(timer); data(); } } var script = document.createElement('script'); script.src = 'http://code.jquery.com/jquery-latest.js'; script.type = 'text/javascript'; document.getElementsByTagName('head')[0].appendChild(script); timer = setInterval(tryData, 100); </code></pre>
