    <p>I'm doing a FireFox extensions. I have an array of URL's. What I want is: redirect the page with <code>document.location.href</code> for all the URL's that I have and then, with a XPath that I have, count the number of elements that the page has.</p> <p>The problem is that I have to wait that the page load was finish before execute the count method with the XPath. This is my code:</p> <pre><code>var actualResult = 0; actualResult = content.document.evaluate('count('+taskModeler.ui.getStatus()+')', content.document, null, XPathResult.NUMBER_TYPE, null).numberValue; for(var i=0; i&lt;taskModeler.ui.getPageContent().length;i++) { content.document.location.href = taskModeler.ui.getPageContent()[i].getAttribute("href"); //only if the page was loaded execute the next line actualResult+=content.document.evaluate('count('+taskModeler.ui.getStatus()+')', content.document, null, XPathResult.NUMBER_TYPE, null).numberValue; } </code></pre> <p><code>getPageContent()</code> returns an array that contains a <strong>set of URL's</strong>. For each of these URL's I have to load the page to get acces to the document and then count the occurrences that returns the XPath. But if the page not was loaded the count method doesn't work because returns the results of the actual page, not the page that was loaded in <code>content.document.location</code>.</p> <p>How can I do that?</p>

    1. COHow you can do *what*? Get page data before the page was loaded? You cannot. Or is the question "How do I wait until the page finishes loading"?

    2. COI have to execute the count method only when the page finish to load. So, ¿how can I do this in the for loop that I show in my code?

    3. CODo you actually need to *see* the page loaded? Or are you just trying to retrieve the data from the page so that you can run a query against it?

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.
