<p>Here is something that I've used for ages now and all of the sudden I get these strange behaviours, maybe someone knows the reason why? Here is my HTML:</p> <pre><code><div class="tooltip" id="tooltip"></div> <input type="button" name="hide" value="hide" onclick="hide('tooltip');" /> <input type="button" name="show" value="show" onclick="show('tooltip');" /> </code></pre> <p>Here is the JavaScript below the HTML code:</p> <pre><code> <script type="text/javascript"> function hide(id) { document.getElementById(id).style.display = 'none'; } function show(id) { document.getElementById(id).style.display = ''; } </script> </code></pre> <p>Now there shouldn't be anything wrong with this code. It should hide or show tooltip on each button click. Now the weird thing going on is when I click on the hide button it hides itself, and when I click on show nothing happens. Hide is still hidden.</p> <p>Did anyone have similar problem? Is there a work-around for it? Maybe another approach for accomplishing the same thing (pure JavaScript)?</p> <p><strong>UPDATE:</strong> Changed it to block, still isn't working. I mean why would it hide the button I'm clicking on when there is no connection to that whatsoever? I'm using latest Firefox by the way. And I added alert in the function same thing. Here is re-written code:</p> <pre><code>function hide(id) { alert(id); document.getElementById(id).style.display = 'none'; } function show(id) { alert(id); document.getElementById(id).style.display = 'block'; } </code></pre>

Guidance

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.
