    <pre><code>&lt;tr&gt; &lt;td&gt;&lt;label&gt;Birthdate&lt;/label&gt; &lt;input type="text" placeholder="mm/dd/yyyy" name="birthdate" maxlength="10"/&gt; &lt;/td&gt; &lt;/tr&gt; </code></pre> <p>Well, my code is working but I want my "input type text" to auto format like a date (html 5 input type=date) because in my Servlet I convert it to Age. The problem is that, if I use the "input type=date" the conversion is error so I decided to use "input type=text" and it's working. So is it possible to auto put "/" in this format "mm/dd/yyyy"? For example, if the user input 2 character an "/" will auto input etc.</p> <hr> <p>Servlet for birthdate to Age</p> <pre><code> String birthdate = request.getParameter("birthdate"); int monthDOB = Integer.parseInt(birthdate.substring(0, 2)); int dayDOB = Integer.parseInt(birthdate.substring(3, 5)); int yearDOB = Integer.parseInt(birthdate.substring(6, 10)); DateFormat dateFormat = new SimpleDateFormat("MM"); java.util.Date date = new java.util.Date(); int thisMonth = Integer.parseInt(dateFormat.format(date)); dateFormat = new SimpleDateFormat("dd"); date = new java.util.Date(); int thisDay = Integer.parseInt(dateFormat.format(date)); dateFormat = new SimpleDateFormat("YYYY"); date = new java.util.Date(); int thisYear = Integer.parseInt(dateFormat.format(date)); int calAge = thisYear - yearDOB; if (thisMonth &lt; monthDOB) { calAge = calAge - 1; } if (thisMonth == monthDOB &amp;&amp; thisDay &lt; dayDOB) { calAge = calAge - 1; } String age = Integer.toString(calAge); </code></pre> <hr> <p>Update in the form</p> <pre><code>&lt;tr&gt; &lt;td&gt;&lt;label for="inputName"&gt;Birthdate&lt;/label&gt; &lt;input type="text" placeholder="mm/dd/yyyy" id="input_date" name="birthdate" maxlength="10" /&gt; &lt;/td&gt; &lt;/tr&gt; </code></pre> <p>Update in the source</p> <pre><code>&lt;script src="../scripts/formatter.js"&gt;&lt;/script&gt; &lt;script src="../scripts/formatter.min.js"&gt;&lt;/script&gt; &lt;script src="../scripts/jquery.formatter.js"&gt;&lt;/script&gt; &lt;script src="../scripts/jquery.formatter.min.js"&gt;&lt;/script&gt; </code></pre> <p>Added Script</p> <pre><code>&lt;script&gt; $('#input_date').formatter({ 'pattern': '{{99}}/{{99}}/{{9999}}', 'persistent': true }); &lt;/script&gt; </code></pre> <p>I also tried the javascript but it's not working... </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.
