title: change background color through onkeyup of input text box
body: <pre><code>&lt;input id='ad' onkeyup='sc(id)'/&gt;
  &lt;script lang="javascript"&gt;
  function sc(i)
  {
      i.style.backgroundColor="#006400";
  }
  &lt;/script&gt;
  </code></pre>
  
  <p>This is the code I am using to change the background colour of the input box through id, but it is not working. Please suggest some way to change the background colour of the input box.</p>
