    <p>You can bind a function to global ajaxerror events<pre><code>$(document).ajaxError(function(event, request, ajaxOptions, thrownError){ if ( 4==request.readyState) { // failed after data has received alert(ajaxOptions['url'] + " did not return valid json data"); } else { alert("something else wnet wrong"); } });</code></pre> or use $.ajax() instead of $.getJSON()<pre><code>function foo() { // $.getJSON("<a href="http://localhost/test.txt" rel="nofollow noreferrer">http://localhost/test.txt</a>", function(data){}); $.ajax({ type: "GET", url: "<a href="http://localhost/test.txt" rel="nofollow noreferrer">http://localhost/test.txt</a>", success: function (data, textStatus) { alert("succuess"); }, error: function (XMLHttpRequest, textStatus, errorThrown) { alert("request failed: " + textStatus); }, dataType: "json" }); }</code></pre></p> <p>edit: But you might want to keep in mind that both <a href="http://docs.jquery.com/Ajax/jQuery.ajax#options" rel="nofollow noreferrer">ajax(dataType:"json")</a> and <a href="http://docs.jquery.com/Ajax/jQuery.getJSON#urldatacallback" rel="nofollow noreferrer">getJSON()</a> (which simply invokes .ajax(dataType:"json") boil down to <code>data = window["eval"]("(" + data + ")")</code> ...this might not be what you want if you don't know what (arbitrary) data your script requests. And this could explain why firebug is catching a syntax error when you feed it an html document instead of json data.<br> In that case better request dataType:"string" und run the data through a fully fledged json parser lib. </p>

    1. COThanks for the detailed code response, VolkerK. I think both of these examples would work if the URL itself was returning an error of some sort. I tried including your first example. The issue, however, is that the URL loads fine but it isn't a valid JSON object. When jQuery tries to parse it, it throws a syntax error on the data provided.

    2. COBoth code snippets were able to tell a mere connection problem from data format trouble when I tested it. I'd prefer the .ajax() approach. Then textStatus is =="parserror" if the data isn't JSON.

    3. COOdd, still no dice. I changed my process from $.getJSON to $.ajax, but Firebug still throws the syntax error instead of any alert messages. Thanks for the help in any regard.

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).
