    <p>Very new to javascript and html-type stuff. I wanted to just make a quick example using input from a user and outputting it into a table. I'm having trouble getting the window prompt to actually come up though. I imagine there is somethign very obvious that I am doing wrong but I'm not currently seeing it...I am taking a class in school but this isn't a homework assignment, just exercises I am doing on my own.</p> <p>Is this something with the while loop? Any suggestions as to how I should keep prompting the user until they state otherwise? </p> <pre><code>&lt;!DOCTYPE html&gt; &lt;html&gt; &lt;head&gt; &lt;meta charset="utf-8"&gt; &lt;title&gt;Mileage Record&lt;/title&gt; &lt;style type = "text/css"&gt; table { width:300px; border-collapse:collapse; background-color:lightblue; } table, td, th { border: 1px solid black; padding: 4px; } th { text-align: left; color: white; background-color: darkblue } tr.oddrow { background-color: white; } &lt;/style&gt; &lt;script&gt; var milesDriven; var gallonsUsed; var mpg; var anyMore; document.writeln("&lt;table&gt;"); document.writeln("&lt;thead&gt;&lt;tr&gt;&lt;th&gt;Miles Driven&lt;/th&gt;"); document.writeln("&lt;th&gt;Gallons Used&lt;/th&gt;"); document.writeln("&lt;th&gt;MPG&lt;/th&gt;"); document.writeln("&lt;/tr&gt;&lt;/thead&gt;&lt;tbody&gt;"); while (anyMore == true) { milesDriven = window.prompt("How many miles did you drive?"); gallonsUsed = window.prompt("How many gallons did you use?"); mpg = milesDrive/gallonsUsed; document.writln("&lt;tr&gt;&lt;td&gt;" + milesDriven + "&lt;/td&gt;&lt;td&gt;" + gallonsUsed + "&lt;/td&gt;&lt;td&gt;" + mpg + "&lt;/td&gt;&lt;/tr&gt;"); anymore = confirm("Do you have any more data to input?"); } document.writeln("&lt;/tbody&gt;&lt;/table&gt;"); &lt;/script&gt; </code></pre> <p><br> </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.
