    <p>I've got a problem with my JSONP request.. The data won't be displayed, Firebug shows an "invalid label" error..</p> <p><img src="https://i.stack.imgur.com/gBEj1.png" alt="enter image description here"></p> <p>My JavaScript:</p> <pre><code>$.ajax({ url: link, dataType: "jsonp", beforeSend: function(xhr) { var base64 = btoa(username + ":" + password); xhr.setRequestHeader("Authorization", "Basic" + base64); xhr.overrideMimeType("application/json"); }, jsonpCallback: "getResources" }) function getResources(data) { alert(data); alert(JSON.parse(data)); $.each(data.groupStatus, function(i, item) { $("body").append("&lt;p&gt;ID: " + item.id + "&lt;/p&gt;"); }); } </code></pre> <p>My JSON:</p> <pre><code>{ "groupStatus": [ { "id": "Application Layer Configuration-ApplicationLayer", "time": 1332755316976, "level": 0, "warningIds": [], "errorIds": [] }, { "id": "Application Layer-ApplicationLayer:nscalealinst2", "time": 1333431531046, "level": 0, "warningIds": [], "errorIds": [] } ] } </code></pre> <p>My HTML:</p> <pre><code>&lt;html&gt; &lt;head&gt; &lt;title&gt;Monitor&lt;/title&gt; &lt;link href="css/gadget.css" rel="stylesheet" type="text/css" /&gt; &lt;script type="text/javascript" src="js/jquery-1.7.2.js"&gt;&lt;/script&gt; &lt;/head&gt; &lt;body&gt; &lt;div id="content"&gt;&lt;/div&gt; &lt;script type="text/javascript" src="js/gadget.js"&gt;&lt;/script&gt; &lt;/body&gt; </code></pre> <p></p> <p>The request works fine, but anyway the data isn't displayed.</p> <p><img src="https://i.stack.imgur.com/tABcy.png" alt="enter image description here"></p> <p>Im searching for a solution for days.. Can somebody help me? Thank you in advance!</p> <p><strong>SOLUTION</strong> (update: 06.09.12)</p> <p>I've solved this problem. The server (REST interface) on which the was executed had no callback function implemented.. Another way to set up crossdomain requests WITHOUT using JSONP is to set the following jquery variable:</p> <pre><code>jQuery.support.cors = true; </code></pre>

    1. COThis is because JSON is *not* a valid JS program but it is trying to be used as one. Find out why the JSONP isn't working as expected. (btw, `getRessources` looks like a misspelling.)

    3. COThe response isn't JSONP, it is JSON. JSONP responses are supposed to be wrapped inside a function call like `callback({"foo": "bar"})`

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.

SQuiL has stopped working due to an internal error.

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