    <p>My Ajax cross domain request is failing in IE 9 with "Access denied". I have read through several posts regarding this topic, and AFAIK it should work.</p> <ol> <li>IE9 and jQuery 1.8.1</li> <li>Call is <code>async</code>, <code>jsonp</code> and <code>crossdomain</code>, <code>cache</code> is <code>false</code>. These are the prerequisites I have found. </li> <li>Works in latest Firefox and Chrome.</li> <li><code>jQuery.support.cors</code> is true</li> <li>Even the response header is set: <code>Access-Control-Allow-Origin:*</code> (<a href="https://stackoverflow.com/questions/9485347/jquery-cross-domain-request-response-headers">SO</a>)</li> <li>The returned JSON code would also be correct, have used a checker (also see 3.)</li> </ol> <p>So why is this failing with <strong>Access denied</strong>? Any idea? Could it be because my code is called from within a "JavaScript" library, and not a <code>&lt;script&gt;&lt;/script&gt;</code> tag on the page?</p> <p>What am I missing?</p> <pre><code> // The code is part of an object's method (prototype) // code resides in a library "Mylib.js" $.ajax({ type: 'GET', url: url, cache: false, async: true, crossdomain: true, // typo, crossDomain, see my answer below datatype: "jsonp", // dataType success: function (data, status) { if (status == "success" &amp;&amp; !Object.isNullOrUndefined(data)) { ... } }, error: function (xhr, textStatus, errorThrown) { // access denied } }); </code></pre> <p>-- Edit -- based on Robotsushi's comments, some further research ---</p> <ol> <li>Indeed, cannot find <code>XDomainRequest</code> in the jQuery source code (1.8.1)</li> <li>If I do not set cors (<code>jQuery.support.cors = true</code>) I'll end up with a "No Transport" exception.</li> <li>Still wondering why others obviously succeed with IE9 cross domain requests, e.g. here: <a href="https://stackoverflow.com/questions/9170718/jquery-cross-domain-ajax-jsonp-calls-failing-randomly-for-unknown-reasons-in-som?rq=1">jQuery Cross-Domain Ajax JSONP Calls Failing Randomly For Unknown Reasons In Some IE Versions</a></li> <li><p>The way jQuery handles this, seems to be around the code below, but this is not called in my particular case, no idea why?</p> <p>// Bind script tag hack transport jQuery.ajaxTransport( "script", function(s) {</p> <pre><code>// This transport only deals with cross domain requests if ( s.crossDomain ) { </code></pre></li> <li><p>A similar situation here in year 2010: <a href="https://stackoverflow.com/questions/3362474/jquery-ajax-fails-in-ie-on-cross-domain-calls?rq=1">Jquery $.ajax fails in IE on cross domain calls</a> However, this should have been solved by the later jQuery versions.</p></li> </ol>

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.
