    <p>I am a noob to programming, so I'd appreciate any advice from you more knowledgeable folks out there. I am working on a bit of javascript for a web page and I need the javascript to print to that current HTML page, preferably in the div tag I have set up for that purpose. Here's what I have so far: </p> <pre><code>&lt;html&gt; &lt;head&gt; &lt;title&gt;Tardy Reporting&lt;/title&gt; &lt;script src="students.js" type="text/javascript"&gt; &lt;/script&gt; &lt;/head&gt; &lt;body&gt; &lt;h1&gt;Scan in Student ID&lt;/h1&gt; &lt;form method="POST" name="idForm" onSubmit="getId(parseInt(document.idForm.studentId.value));"&gt; &lt;input type="text" name="studentId" id="studentId"/&gt; &lt;input type="Submit" name="Submit" /&gt; &lt;/form&gt; &lt;div id="div1"&gt;&lt;/div&gt; &lt;p&gt; &lt;/body&gt; &lt;/html&gt; </code></pre> <p>and my JS file:</p> <pre><code>var studentNumberArray = [50011234, 50012345, 50013456]; var studentNameArray = ["Mike Simpson", "Greg Pollard", "Jason Vigil"]; var studentLastPeriodArray = ["George Washington", "Darth Vadar", "Obi Wan Kenobi"]; var tardyArray = [0, 0, 0]; function getId(studentId) { for (i = 0; i &lt; studentNumberArray.length; i++){ if(studentId === studentNumberArray[i]){ tardyArray[i] += tardyArray[i] + 1; document.getElementById('div1').innerHTML='test'; } } } </code></pre> <p>Mind you, this is just the basic framework, so it's not nearly done yet, but the thing that is bugging me is that it'll go through the code correctly and print it out, but the result only lasts a fraction of a second on my browsers (chromium and firefox). Any help would be appreciated.</p>

    2. COThe reason is because you're using a form to submit. This causes the page to refresh after submitting. So the "lasts a second" is because it displays what you want, then submits, then refreshes. A combination of using Kory's and Sofian's answers should help out.

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.
