    <p>It sounds like you just wanted to verify if everything inside the form element was validated. Here are two fiddles I worked up to get you started:</p> <p>1) Regular Javascript</p> <pre><code>function formCheck() { var form = document.getElementById('mainForm'), inputs = form.getElementsByTagName('INPUT'), selects = form.getElementsByTagName('SELECT'), i, errors = []; for (i = 0; i &lt; inputs.length; i++) { if (inputs[i].value.match(/^\s*$/)) { errors.push(inputs[i].title + ' was not set'); } } for (i = 0; i &lt; selects.length; i++) { if (selects[i].selectedIndex === 0) { errors.push(selects[i].title + ' was not set'); } } if (errors.length &gt; 0 ) { alert(errors.join('\n')); return false; } alert('success!'); return true; } </code></pre> <p><a href="http://jsfiddle.net/fstreamz/3Decx/4/" rel="nofollow">http://jsfiddle.net/fstreamz/3Decx/4/</a></p> <p>2) With JQuery</p> <pre><code>function formCheck() { var formElements = $('#mainForm').find('input, select'), errors = []; $.each(formElements, function(i, el) { if ($(el).val().match(/^\s*$/)) { errors.push($(el).prop('title') + ' is blank!'); } }); if (errors.length &gt; 0 ) { alert(errors.join('\n')); return false; } alert('success'); return true; } </code></pre> <p><a href="http://jsfiddle.net/fstreamz/w5KG3/4/" rel="nofollow">http://jsfiddle.net/fstreamz/w5KG3/4/</a></p> <p>A few notes: 1) It checks every input or select element inside a form element with id="mainForm" so you'd have to add that to your form (next to name="myForm"). 2) I added a title attribute to the input/select elements so I could show that in the error message as a reference. 3) It checks for whitespace in input boxes and consider that invalid. 4) in the jsFiddle, it returns false even in success so the form doesn't submit for demonstration purposes. That should be changed to true if you use it.</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).
