Body
<p>Below is my code. I want the div to appear when it is selected, however, when I press submit, the word <code>undefined</code> appears instead of the words I want it to be.</p> <p>When I use <code>=</code> instead of <code>==</code>, e.g. <code>if(age="toddlers")</code>, the sentence <code>"Bring to picnic"</code> appears for all selected options.</p> <p>Hence, I'm suspecting that it's because I'm not reading the value correctly. I tried </p> <pre><code>if (document.getElementsByTagName('option') == "toodlers") </code></pre> <p>and it's totally not working. I just started learning HTML, CSS and JS. I tried googling for a few hours and I still cannot fix it.</p> <pre><code><form name="outing"> <select id="outing"> <option value="toddlers">Toddlers</option> <option value="children">Children</option> <option value="teenagers">Teenagers</option> <option value="adults">Adults</option> <option value="eldery">Elderly</option> </select> <input type="button" name="button" value="Go!" onClick="familyOuting();"> <input type="reset" value="Reset" onClick="window.location.reload()"/> </form> <script type="text/javascript"> function familyOuting(){ var age = document.getElementById("outing").selectedIndex; if(age=="toddlers"){ var place = "Bring to picnic"; } if(age=="children"){ var place = "Bring to playground"; } if(age=="teenagers"){ var place = "Bring to swimming pool"; } if(age=="adults"){ var place = "Bring to dinner"; } if(age=="elderly"){ var place = "Bring to picnic"; } document.getElementById("xxx").innerHTML=(place); } </script> <div id="xxx"> </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.
