I have an uploadify script in an iFrame which is on another domain. I am attempting to send the file upload <code>data</code> to the page on which the iFrame is embedded on. I have the following code in a iFrame (uploadify script): <pre><code>$('#file_upload').uploadify({ //JS CODE 'onUploadSuccess' : function(file, data, response) { data //data is what must be passed from the iFrame to the script on another site } }); </code></pre> <code>data</code> is what must be passed to the following script on another domain: <pre><code>var myframe, nestedFrame; myFrame = $('#editorf').contents().find('body'); nestedFrame = myFrame.find('#re_contentIframe').contents().find('body'); nestedFrame.append('data'); //data should be replaced with the information from the iFrame </code></pre> I did attempt the following code: iFrame Code - Page B <pre><code>$('#file_upload').uploadify({ //JS CODE for UPLOADIFY 'onUploadSuccess' : function(file, data, response) { window.postMessage('http://iframe-domain.net/uploads/' + data,'http://iframe-domain.net'); } }); </code></pre> Receiving Page Code - Page A <pre><code>$(function() { window.addEventListener('message', receiver, false); function receiver(e){ if (e.origin == 'http://iframe-domain.net'){ var myframe, nestedFrame; myFrame = $('#editorf').contents().find('body'); nestedFrame = myFrame.find('#re_contentIframe').contents().find('body'); nestedFrame.append(e.data); } } }); </code></pre> This doesn't work. I do receive this error message: <pre><code>Error: Permission denied to access property 'toString' ...a);if(Z){var Y=0;(function(){if(typeof Z.GetVariable!=D){var ab=Z.GetVariable("$... jquery.uploadify.js (line 17) </code></pre> The uploadify Script does work as the file is uploaded but it doesn't appear to pass the data to the page. I am not convinced this error is the reason the page isn't working. How do I do this? EDIT To better explain here is an example: A person goes to Page A (the main page). On Page A an iFrame is embedded on that page. Inside the iFrame is an uploadify script to allow users to upload a file. A person uploads a file the uploadify script returns the file name. Example: <code>528050f030522.jpg</code>. Once the uploadify script has this information it should send it to Page A's script which then runs and inserts the file name into the page.

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.
