Clearing output text from the HTML body

Hello,

I wish to clear text that has been outputted by javascript to an HTML element such as the body. The text is outputted using the appendChild() method. I want to be able to clear any text that has been added that way.

I've provided some sample code of what I want to do below:

Expand|Select|Wrap|Line Numbers

 
  <head>

    <meta content="text/html; charset=iso-8859-1" http-equiv="Content-Type">

    <title></title>

    <script type="text/javascript">
 
function outputLine()

{

  var li = document.createElement('LI');

  li.appendChild(document.createTextNode("Hello!"));

  document.getElementById('updateTarget').appendChild(li);

}
 
function clearBody()

{

    //??? document.getElementById('updateTarget').???

}

   </script>

  </head>

  <body id='updateTarget' onLoad='outputLine()'>

    <form name=select onsubmit='clearBody()'>

        <input type=submit value="Clear Me">

      </form>

  </body>

Welcome to TSDN!

Unless you keep tabs on what has been added, I don't think there's an easy way of doing this. Every time, you use appendChild to add something, store the object in an array and then remove these using removeChild in your clearBody() function.

Thank you, although it's not the way I hoped to do it, it works.

Yes, not clean, but I can't think of anything else at the moment.
