    <p>I'm not quite sure what additional information you need, as you seem to be aware of all the ingredients for making this happen: You know that you want to detect an event, you know that you need to call a function, so I'm hoping I haven't missed something about what you're asking. I'm going to assume that you just need to know how to tie all these parts together.</p> <p>The simplest example might be:</p> <pre><code>&lt;input type="text" id="Quantity" value="10" onchange="document.getElementById('Amount').value = parseInt(document.getElementById('Quantity').value,10) * 10.0;" /&gt; $&lt;input type="text" id="Amount" value="100" /&gt; </code></pre> <p>though it's worth noting that this does not follow best-practices, which would involve binding an event listener separately.</p> <p>On the off-chance that you accidentally typed "button" when you meant "field", I will also mention that you can update any other element's innner HTML with the ''innerHTML'' attribute, eg:</p> <pre><code>&lt;input type="text" id="Quantity" value="10" onchange="document.getElementById('Amount').innerHTML = parseInt(document.getElementById('Quantity').value,10) * 10.0;" /&gt; $&lt;span id="Amount"&gt;100&lt;/span&gt; </code></pre> <p>Of course, you can define the actual logic elsewhere, and just use ''onchange="yourFunction();"'' instead of putting everything inline, as well.</p> <p>I know you mentioned "onchange" and "onfocus", though personally I tend to prefer "onkeyup", so that values will change as the user is typing.</p> <p>Apologies if I've completely missed the point in your question.</p>

    1. COActually, I didn't type button instead of field. I want to trigger the Amount field to get a new value.

    2. COOkay, sorry for the wild guess :) The answer above does indeed cause the Amount field to get a new value, though Dave Zych puts it better.

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).
