    <p>I'm building a quick website; because of its nature I can afford to host it in my Dropbox public folder. I'm trying to read some text files using XMLHttpRequest:</p> <pre><code>function getParameters() { var oRequest = new XMLHttpRequest(); var sURL = "http://dl.dropbox.com/u/7828009/Relay%20Fundraising%20Site/parameters.txt"; // var sURL = "file:///parameters.txt"; oRequest.open("GET",sURL,false); oRequest.onreadystatechange = function (oEvent) { if (oRequest.readyState === 4) { if (oRequest.status === 200) { console.log(oRequest.responseText) } else { console.log("Error", oRequest.statusText); } } }; oRequest.setRequestHeader("User-Agent",navigator.userAgent); try { oRequest.send(null) } catch (err) { alert(err); } if (oRequest.status==200) alert(oRequest.responseText); else alert("Error executing XMLHttpRequest call!"); } </code></pre> <p>I'm getting an XMLHttpRequest 101 error in the send() line and I have no idea how to resolve this. The exact error is </p> <pre><code>XMLHttpRequest cannot load http://dl.dropbox.com/u/7828009/Relay%20Fundraising%20Site/parameters.txt. Origin null is not allowed by Access-Control-Allow-Origin. </code></pre> <p>Can I do anything to fix this, or is it because of Dropbox themselves?</p> <p><hr /> <strike> <strong>Update</strong> I've tried loading the file from the dropbox URL directly. </p> <pre><code>http://dl.dropbox.com/u/7828009/Relay%20Fundraising%20Site/main.htm </code></pre> <p>New error is now</p> <pre><code>XMLHttpRequest cannot load http://www.javascripter.net/faq/requested_file.htm. Origin http://dl.dropbox.com is not allowed by Access-Control-Allow-Origin. </code></pre> <p>What can I do about this?</strike></p> <p><hr /> <strong>Update 2:</strong> D'oh moment…I had left in a test URL to see if it was a Dropbox issue. It linked to an external file. Fixing that fixed my issue. </p> <p>The principal problem was running the file off the local copy. Running from the Dropbox public URL fixed the issue. Thanks <a href="https://stackoverflow.com/a/10375507/472768">Quentin</a>, for indirectly leading me to the answer.</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.
