    <p>You can't make cross-domain AJAX calls across domains. This is a security feature in web browsers to prevent malicious JavaScript code from scraping rendered data in a web page and then shipping it off to some rogue website on some other domain.</p> <p>By restricting AJAX requests to same domain, browser vendors ensure that JavaScript imported from other sources cannot send data to any server other than the server the HTML page was served from.</p> <p>In Internet Explorer, it's prompting you, but any smart user who encounters such a message is likely to say no. Presenting your users with such warning messages is <em>not</em> a good design practice and does not inspire confidence in the legitimacy of your application.</p> <p>The only way that you can send data across domains is to use a browser hack technique called "script tag remoting", which essentially involves using HTML elements that aren't restricted by the same domain policy. For instance <code>script</code> tags can make HTTP GET requests to any server:</p> <pre><code>// create a script tag element var script = document.createElement("script"); // set the attribute, using the URL to pass data via query parameters script.setAttribute("src","http://192.168.9.11/userInput/?key="+userInput); script.setAttribute("type","text/javascript"); // add the script tag to the document head, forcing an HTTP request document.getElementsByTagName("head")[0].appendChild(script); </code></pre> <p>Using this method, you can send data to a remote server. Note that, to get JSON data back, you must wrap it, or pad it, in a JavaScript function and define a callback in the JavaScript code to handle the response:</p> <pre><code>function callbackJsonHandler(data) { alert(data); // This is the JSON data } </code></pre> <p>And your server-side code must return content text/javascript, calling the handler, and passing your JSON as an argument:</p> <pre><code>callbackJsonHandler({"key":"value","key1":"value2"}); </code></pre> <p>When the browser downloads the JavaScript to the browser, the JavaScript runs immediately, giving you a hook to use to access the JSON in the response.</p> <hr> <p>Since you're using jQuery, you can also check out <a href="https://github.com/jaubourg/jquery-jsonp" rel="nofollow">jQuery JSONP</a>, or JSON with Padding, which can be used to generate a JavaScript response so that you can handle callbacks from these requests to the remote server. Note that the server must be setup to handle JSONP requests for this to work properly, similar to the above setup.</p>

    1. COIs there any other method to access the cross domain data with out using ajax. I read some where that if we made the Access-Control-Allow-Origin to (site or *) we can access the cross domain data.

    2. COlol, yes. Script tag remoting and JSONP. Neither of those are AJAX. :) Well, you could use a proxy, but that's a bit more complex. Basically, your page calls your server via AJAX, and your server makes the HTTP request to the remote server, then takes the response and sends it back. `page -> your server -> remote server`

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.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
