title: HTML Form Plus Button
body: <p>I am using an html form that submits data to a MYSQL database. I need to add a button that will increase the number in the text box by one every time pressed. My code looks like this:</p>
  
  <pre><code>&lt;label for="htop"&gt;Top: &lt;/label&gt;
  &lt;input type="button" name="decrease" value="-" /&gt;&lt;input type="text" name="htop" value="0" /&gt;
  &lt;input type="button" name="increase" value="+" /&gt;
  </code></pre>
  
  <p>What is the best way to do this?</p>
