    <p>Following on from a p<a href="https://stackoverflow.com/questions/2279997/">revious question</a> where I asked about disabling a submit button until all ajax calls have finished returning...</p> <p>It seems that people are still managing to submit the form even with the button disabled and a warning sign. I guess it could be from pressing 'enter' in a text input.</p> <p>How do I go about disabling the whole form, rather than just the submit button?</p> <p>The code so far is:</p> <pre><code>// if we're waiting for any ajax to complete we need to disable the submit $(document).ajaxStart(function() { $(".ajaxbutton").attr("disabled", "disabled"); // if it's taken longer than 250ms display waiting message timer = setTimeout(function() { $('#processingAlert').html(' ...please wait one moment'); $('#processingAlert').show(); }, 250); }) $(document).ajaxComplete(function() { $(".ajaxbutton").removeAttr("disabled"); $('#processingAlert').hide(); // cancel showing the message when the ajax call completes. clearTimeout(timer); }); </code></pre> <p>One other thing that I should mention which could be causing a problem is that there are multiple ajax calls happening at the same time, EG one div receives hidden inputs and another div elsewhere on the page shows a price total for instance.</p> <p>Would the fact that some ajax calls are completing quickly negate the disabling effect of ajaxStart? EG ajax call1 and ajax call2 both fire the ajaxStart - call1 finishes really quickly, would it re-enable the form while we are waiting for call2 to complete?</p> <p>Is there a better way of doing this where we could simply test if ALL ajax calls have completed?</p>

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.
