Body
<p>So I'm building a JavaScript calculator, and I have the class numerical, and whenever that class gets click it iterates a code sequence as you can see in my javascript below, but it won't retrieve the innerHTML value of the one it clicked for some reason. Do I need to move on to ID's or can I make this work?</p> <p>JavaScript</p> <pre><code>$(document).ready(function(){ $('.numerical').on('click', function(){ var innerDisp = document.getElementById('display').innerHTML; var num = document.getElementById(this).innerHTML; document.getElementById('display').innerHTML = innerDisp + num; }); }); </code></pre> <p>HTML</p> <pre><code><body> <center> <div id="calculator"> <div id="display"></div> <button class="numerical" id="0">0</button> <button class="numerical" id="1">1</button> <button class="numerical" id="2">2</button> <button class="function" id="add">+</button> <button class="numerical" id="3">3</button> <button class="numerical" id="4">4</button> <button class="numerical" id="5">5</button> <button class="function" id="subtract">-</button> <button class="numerical" id="6">6</button> <button class="numerical" id="7">7</button> <button class="numerical" id="8">8</button> <button class="function" id="multiply">x</button> <button class="numerical" id="9">9</button> <button class="function" id="c">C</button> <button class="function" id="ce">CE</button> <button class="function" id="divide">/</button> </div> </center> <script src="calculator.js"></script> </body> </code></pre>

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.
