    <p>I think that your problem is this line:</p> <pre><code>$('input').attr('disabled','disabled'); </code></pre> <p>You're disabling ALL the inputs, including, I'd guess, the ones whose data the form is supposed to submit. </p> <p>To disable just the submit button(s), you <strong>could</strong> do this:</p> <pre><code>$('button[type=submit], input[type=submit]').prop('disabled',true); </code></pre> <p>However, I don't think IE will submit the form if even those buttons are disabled. I'd suggest a different approach.</p> <h2>A jQuery plugin to solve it</h2> <p>We just solved this problem with the following code. The trick here is using jQuery's <code>data()</code> to mark the form as already submitted or not. That way, we don't have to mess with the submit buttons, which freaks IE out.</p> <pre><code>// jQuery plugin to prevent double submission of forms jQuery.fn.preventDoubleSubmission = function() { $(this).on('submit',function(e){ var $form = $(this); if ($form.data('submitted') === true) { // Previously submitted - don't submit again e.preventDefault(); } else { // Mark it so that the next submit can be ignored $form.data('submitted', true); } }); // Keep chainability return this; }; </code></pre> <p>Use it like this:</p> <pre><code>$('form').preventDoubleSubmission(); </code></pre> <p>If there are AJAX forms that <strong>should</strong> be allowed to submit multiple times per page load, you can give them a class indicating that, then exclude them from your selector like this:</p> <pre><code>$('form:not(.js-allow-double-submission)').preventDoubleSubmission(); </code></pre>

    1. COJust a pointer - wouldn't it be better to cache the `$(this)` to a `var that = $(this)`?

    2. CO@Stuart.Sklinar - good idea. I used `$form` though - 'form' because it's more descriptive, and the leading `$` because by my convention, that means it's a jQuery object.

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).
