    <p>There is no such thing as "jQuery functions", the jQuery code just usually uses an anonymous JavaScript function.</p> <p>To move the contents of the loop into a named function would look like this:</p> <pre><code>$(".x").click( function() { for (var i=0; i&lt;50; i++) toggleItem(i) }); function toggleItem(i) { if ($("#x"+i).is(':hidden')) { $("#x"+i).show(); } else { $("#x"+i).hide(); } } </code></pre> <p>However, you could use the cascading properties of CSS to toggle all the items with a simple JavaScript statement instead of looping through all the elements. Example:</p> <p>CSS:</p> <pre><code>&lt;style type="text/css"&gt; .StateOne .InitiallyHidden { display: none; } .StateTwo .InitiallyVisible { display: none; } &lt;/style&gt; </code></pre> <p>HTML:</p> <pre><code>&lt;div class="StateOne" id="StateContainer"&gt; &lt;div class="InitiallyVisible"&gt;Visible first&lt;/div&gt; &lt;div class="InitiallyHidden"&gt;Visible second&lt;/div&gt; &lt;div class="InitiallyVisible"&gt;Visible first&lt;/div&gt; &lt;div class="InitiallyHidden"&gt;Visible second&lt;/div&gt; &lt;div class="InitiallyVisible"&gt;Visible first&lt;/div&gt; &lt;div class="InitiallyHidden"&gt;Visible second&lt;/div&gt; &lt;div class="InitiallyVisible"&gt;Visible first&lt;/div&gt; &lt;div class="InitiallyHidden"&gt;Visible second&lt;/div&gt; &lt;/div&gt; </code></pre> <p>JavaScript:</p> <pre><code>$('.x').click(function() { var s = document.getElementById('StateContainer'); s.className = (s.className == 'StateOne' ? 'StateTwo' : 'StateOne'); }); </code></pre>

    1. COThis is great. I really like your alternate approach and I almost understand it too. One question: Did you make a mistake when you defined the styles for StateOne and StateTwo - they are both set to "display:none" - shouldn't StateTwo be visible?

    2. CO@Charlie: No, it's not a mistake in the styles. The InitiallyHidden class is hidden when the parent element has the class StateOne and visible for StateTwo. The InitiallyVisible class is the opposite. That way you can have one set of elemenets visible for each state.

    3. COI'm trying this out on my machine but I can't activate the change of state. I put your Javascript inside document ready and then I defined a button: <button class="x">Change StateContainer</button>. But this doesn't change the state. Did I forget to do something? I will edit my question to show you the complete code.

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).
