    copied!<p>I have two projects, an older one, which works, and a newer one. Both projects have to make a cross-domain call.</p> <p>On the older project, I use jsonp to talk to the server and get a response, such as:</p> <pre><code>var myUrl = "http://www.myserver.whatever/somepage.php"; jsonp(myUrl, "ajaxResponse"); function ajaxResponse(data) { alert(data.response); } </code></pre> <p>In my new totally unrelated project, I have to talk to a service. The web page is a local file on the client talking to a CentOS daemon written by a software vendor. I can communicate to the daemon through REST GET calls. An example of a call would be, which works, as I entered the following in a Mozilla Firefox browser window:</p> <p>localhost:8080/mfds/info</p> <p>I thought that the easiest way to communicate to the daemon would be through jsonp, like I did previously, so:</p> <pre><code>var myUrl = "http://localhost:8080/mfds/info"; jsonp(myUrl, "ajaxResponse2"); function ajaxResponse2(data) { alert(data.response); } </code></pre> <p>Sadly, I never get to the ajaxResponse2() function. What am I doing wrong? Is jsonp() not a REST GET call? How do I fix the code?</p> <p>I am using:</p> <pre><code>&lt;script type="text/javascript" src="js/jsonpCrossDomain.js"&gt;&lt;/script&gt; </code></pre> <p>to load the jsonp script. As mentioned earlier, if I use the URL associated with my old project, the code works, just not with localhost:8080:/mfds/info, which works nicely in a browser. The daemon service returns html code.</p> <p>UPDATE: Based on the comment below, I did not realize that jsonp has to be on both sides. I originally tried the following code, but this code threw a cross domain error (or so I think, actual error below), which led me to try the JSONP call, but I cannot use that either.</p> <pre><code>$.ajax({ url: 'localhost:8080/mfds/info', type: "GET", dataType: "html", error: function (error) { alert(JSON.stringify(error)); }, complete: function (data_response) { alert(data_response.responseText); }, success: function (data) { alert(data); } }); </code></pre> <p>Error message from the $.ajax call:</p> <p>{"readyState":0,"status":0,"statusText":"[Exception... \"\" nsresult: \"0x805e0006 ()\" location:\"js frame ::file:///home/user/Documents/myproejct/js/jquery-2.0.3.min.js :: :: line 6\" data: no]"}</p>
