Body
<p>I'm trying to submit a form using IEs fireEvent method. Here's some simple test code:</p> <pre><code><html> <head> <script type="text/javascript"> function fireSubmit () { if (document.createEventObject) { var event = document.createEventObject (); var fired = document.forms['fireForm'].fireEvent("onsubmit", event); alert("event fired: " + fired + "; event returnValue: " + event.returnValue); } } </script> </head> <body> <button onmouseover="fireSubmit();"> Hover to submit </button> <form name="fireForm" action="action.html" method="post"> <input type="submit" name="submit" value="submit"> </form> </body> </html> </code></pre> <p>And here's the simple action.html that should get submitted:</p> <pre><code><html> <body> <script>alert('submitted');</script> </body> </html> </code></pre> <p>If I hover over the button, the event does get created and IE claims it was fired. An alert pops up that says "event fired: true; event returnValue: <strong>undefined</strong>", but the action.html alert is never shown and the returnValue is never set contrary to what <a href="http://msdn.microsoft.com/en-us/library/ms536423(v=vs.85).aspx" rel="nofollow">this</a> claims. However, if I just click on the submit button, the form is actually submitted and the "submitted" dialog shows. </p> <p>What am I doing wrong? Am I misusing IE in some heinous way?</p> <p><em><strong>edit</em></strong>: Basically I'm trying to use the event model to catch problems down the line. The following code using <a href="https://developer.mozilla.org/en/DOM/element.dispatchEvent" rel="nofollow">dispatchEvent</a> works fine in non-IE browsers for the same purpose:</p> <pre><code> if (document.createEvent) { var event = document.createEvent("HTMLEvents"); event.initEvent("submit", false, false); var returnValue = document.forms['fireForm'].dispatchEvent(event); alert("event returnValue: " + returnValue); } </code></pre>

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.
