    <p>I have a script that does not allow submit until the form value is changed from the initial page-render.</p> <p>Everything works, except for the radio buttons. When I try to check or uncheck them, they have no effect on the button.</p> <p>Anyone see what is wrong? (I want to do a check to see if one or more of the checkboxes has changed from the initial page-render)</p> <pre><code>$(document).ready(function () { var button = $('#submit-data'); $('input, select, checkbox').each(function () { $(this).data('val', $(this).val()); }); $('input, select, checkbox').bind('keyup change blur', function () { var changed = false; $('input, select, checkbox').each(function () { if ($(this).val() != $(this).data('val')) { changed = true; } }); $('#submit-data').prop('disabled', !changed); }); }); </code></pre> <h1>Edit:</h1> <p>Checkbox html:</p> <pre><code>&lt;input checked="checked" id="contactemail" name="contactemail" type="checkbox" /&gt; &lt;input id="contactsms" name="contactsms" type="checkbox" /&gt; &lt;input checked="checked" id="contactphone" name="contactphone" type="checkbox" /&gt; </code></pre> <h1>Edit 2:</h1> <p>New code from answer from Marikkani Chelladurai. It is almost working, but it only works if the checkbox is not checked initially, and then checked by the user. <a href="http://jsfiddle.net/7YLGa/2/" rel="nofollow">Link to JSFiddle</a></p> <pre><code>$(document).ready(function() { var button = $('#submit-data'); $('input, select').each(function () { $(this).data('val', $(this).val()); }); $('input[type=radio], input[type=checkbox]').each(function (e) { $(this).data('val', $(this).attr('checked')); }); //For radio buttons $('input, select').bind('keyup change blur', function (e) { var changed = false; if (e.target.type == "radio" || e.target.type == "checkbox" ) { if($(this).data('val') != $(this).attr('checked')){ changed = true; } } else { if ($(this).val() != $(this).data('val')) { changed = true; } } $('#submit-data').prop('disabled', !changed); }); }); </code></pre> <p><a href="http://jsfiddle.net/7YLGa/2/" rel="nofollow">Link to JSFiddle</a></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.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
