    <p>I've spent a long time trying different things to get this to work but nothing does and documentation is not helping much.</p> <p>I'm trying to populate a form inside an iframe that I dynamically inject into a page. To inject that iframe I do:</p> <pre><code>myObject.iframe = document.createElement("iframe"); myObject.iframe.setAttribute("src", data.url); myObject.iframe.setAttribute("id","extension-iframe"); myObject.window.document.getElementById('publisher').appendChild(myObject.iframe); myObject.iframe.addEventListener("load", function(){ myObject.populate(data); }, false); </code></pre> <p>which works fine and DOES trigger the populate() method. My problem is getting the document or window objects for that iframe. I've tried all of the following:</p> <pre><code>myObject.iframe.window myObject.iframe.document myObject.iframe.content </code></pre> <p>but these are all undefined.</p> <p>I also tried passing the event object to that iframe's load event listener and then doing:</p> <pre><code>event.originalTarget </code></pre> <p>But that didn't work either.</p> <p>I am reading the following documentation:</p> <ul> <li><a href="https://developer.mozilla.org/En/Working_with_windows_in_chrome_code" rel="nofollow noreferrer">https://developer.mozilla.org/En/Working_with_windows_in_chrome_code</a></li> <li><a href="https://developer.mozilla.org/en/Code_snippets/Interaction_between_privileged_and_non-privileged_pages" rel="nofollow noreferrer">https://developer.mozilla.org/en/Code_snippets/Interaction_between_privileged_and_non-privileged_pages</a></li> </ul> <p>But either I'm not understanding it or it's just not properly explained.</p> <p>Can anyone shed some light?</p> <p>Thanks!</p>

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.
