    <p>I am basically a newbie with javascript. I want to populate a div in my webpage from a select form found on the same page, when the user selects the book and chapter he wants to view and presses the submit button. Here the code:</p> <pre><code>&lt;script type="text/javascript" charset="utf-8"&gt; var setArray = newArray( bk1, 001, "this is my chapter content for the &lt;div&gt;", bk1, 002, "this is my chapter content for the &lt;div&gt;", bk1, 003, "this is my chapter content for the &lt;div&gt;", bk2, 001, "this is my chapter content for the &lt;div&gt;", bk2, 002, "this is my chapter content for the &lt;div&gt;" etc.... ); &lt;/script&gt; &lt;form&gt; &lt;select id="book"&gt; &lt;option value=""&gt;Select Book&lt;/option&gt; &lt;option value="bk1"&gt;Book 1&lt;/option&gt; &lt;option value="bk2"&gt;Book 2&lt;/option&gt; &lt;option value="bk3"&gt;Book 3&lt;/option&gt; &lt;/select&gt; &lt;select id="chapter"&gt; &lt;option value=""&gt;Select Chapter&lt;/option&gt; &lt;option value="001"&gt;1&lt;/option&gt; &lt;option value="002"&gt;2&lt;/option&gt; &lt;option value="003"&gt;3&lt;/option&gt; &lt;/select&gt; &lt;button id="button" type="submit"&gt;View&lt;/button&gt; &lt;/form&gt; &lt;div id="content"&gt; I want the content from the js array for the selected book and chapter to be placed here without reloading the page. &lt;/div&gt; </code></pre> <p>Note: I have simplified the code to make it a little easier to follow. I am sure my js array is incorrect and needs fixing for my purpose. Also, I don't want the page to refresh, only the div to update. Thanks for any help.</p>

    2. COyou would ideally want a better structure array. For example, an array of objects, where each object has a book, chapter and comment property. Then you can search the array on an event. Of course, the whole "hard-coded" option is a bad idea anyway. You could use AJAX to query the server and get a lookup on a database (for example)

    3. COYou should consider using an Ajax library. I would recommend that you go with jQuery which also has quite a lot of other handy features.

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.
