    <p>There are several questions on Stack Overflow saying cross domain AJAX request etc will not work because of security reasons. Some questions like <a href="https://stackoverflow.com/questions/4840825/ajax-with-jquery-200-ok-but-not-success">this explain</a> this. (Please let me know if I am wrong.)</p> <p>This is working perfectly fine:</p> <pre><code>$(document).ready(function() { $.getJSON("http://search.twitter.com/search.json?q=test&amp;callback=?", function(data) { alert("test alert outside loop"); $.each(data.results, function() { alert("test alert inside loop"); }); }); }); </code></pre> <p>But just replacing the URL with my application won't work. In that case response code is <code>200</code>, but there's no response data. There is an hit on my application; I can see that in console.</p> <pre><code>$(document).ready(function() { $.getJSON("http://192.168.1.2:3000/cities.json?callback=?", function(data) { alert("test alert outside loop"); $.each(data.results, function() { alert("test alert inside loop"); }); }); }); </code></pre> <p>I am developing a very simple mobile app using PhoneGap so I need to make this call using JavaScript. But the main thing that's confusing me is why the Twitter call is working, but the call to my app isn't. I've also tried to remove the <code>protect_from_forgery</code> call in my application controller in my Rails app, but i don't think that matters.</p> <p><strong>EDIT</strong></p> <p>i have deployed the app on <a href="http://deals.textadda.com/cities.json" rel="nofollow noreferrer">http://deals.textadda.com/cities.json</a> now check it... Its not working..</p> <p>U can try it. these two links <a href="http://jsfiddle.net/2arbY/" rel="nofollow noreferrer">http://jsfiddle.net/2arbY/</a> <a href="http://jsfiddle.net/fHxf9/" rel="nofollow noreferrer">http://jsfiddle.net/fHxf9/</a></p>

    1. COWhere are you calling these functions from? A server, or your local machine? Is `http://192.168.1.2` the IP address of the machine running the script?

    3. CO[This seems related](http://stackoverflow.com/questions/6591987/json-received-but-error-for-resource-interpreted-as-script-but-transferred-with/6592013#6592013). Looks like you're returning JSON from the server, not JSONP.

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.
