    <p>I have got a test page to use Ajax to make a http 'delete' request to a server. The following JS code works as intended in IE7, but it does not work in Firefox (unless I make the ajax call asynchronous).</p> <p>In Firefox, unless async is false, the error callback gets triggered with status of 0. </p> <ol> <li>Can anyone assist in explaining why this is apparently working in Firefox if the call is synchronous?</li> <li>In the context of this page, a synchronous call is not a bad thing, however I have read that this should be avoided as this would effectively freeze the browser window until the response had returned. Is there an alternative solution anyone can suggest?</li> </ol> <p>The relevant code is below:-</p> <pre><code>&lt;script src="${url.context}/scripts/jquery-1.3.2.min.js"&gt;&lt;/script&gt; &lt;SCRIPT LANGUAGE="JavaScript"&gt; jQuery.noConflict(); function deleteImage(nodeParam) { alert('hello'); var options = { type: 'DELETE', async: false, url: '${url.context}/service/api/asset/delete?alf_ticket=${session.ticket}'+'&amp;format=text'+'&amp;'+nodeParam, dataType: 'json', success: function(data, textStatus) { jQuery('#result-div').html(''); if (data['ok'] == true) { //jQuery('#result-div').html('Delete successful using parameter - ' + nodeParam); alert("Delete successful" ); } else { alert( "Response 'ok' set to 'false' on success callback!" ); jQuery('#result-div').html('Delete failed!'); } }, error: function (request, textStatus, errorThrown) { //jQuery('#result-div').html('Delete failed!'); alert("Delete Failed"); alert(request.status); //alert("Error callback triggered, request failed with status: " + request.status + ' ' + request.responseText); } }; jQuery.ajax(options); } // End --&gt; &lt;/script&gt; </code></pre> <p>Thanks J</p>

    1. COAfaik there is no `delete` type. Use get or post.

    2. COI believe delete is supported. But it may not be supported for all browsers.

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).
