    <p>I have a drupal rendered webform that generates the following HTML for a SELECT list. The list is essentially for booking a table in a restaurant. My client wants me to preselect the meal based on the time of the day. So if its between midnight and 3:00 pm Lunch should be preselected automatically. After 3:00 pm till 10:30pm the form should display with dinner preselected. </p> <pre><code>&lt;select class="form-select required" name="submitted[meal]" id="edit-submitted-meal"&gt; &lt;option selected="selected" value="1"&gt;Lunch&lt;/option&gt; &lt;option value="2"&gt;Dinner&lt;/option&gt; &lt;option value="3"&gt;Sunday Dining&lt;/option&gt; &lt;/select&gt; </code></pre> <p>I created the following JS snippet hoping to achieve the objective but it doesn't seem to work on Page load</p> <pre><code>window.onload() { var today = new Date("&lt;?php echo date("Y-m-d H:i:s"); ?&gt;"); var day = date.getDay(); var hour = date.getHours(); var meallist = document.getElementbyId("#edit-submitted-meal"); if (day == 0) { meallist.options[3].selected==true; } else { if (hour &gt; 15 &amp;&amp; hour &lt; 22) { meallist.options[2].selected==true; } else if (hour &gt; 22 &amp;&amp; hour &lt; 24 { meallist.options[1].selected==true; } else if (hour &gt; 0 &amp;&amp; hour &lt; 15 { meallist.options[1].selected==true; } } } </code></pre> <p>Would appreciate any help. Thank you in advance.</p> <p>PS : The PHP code injects the date into the javascript so when the page is rendered the line becomes var today = new Date("2013-01-15 15:49:45");</p>

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.
