    How to display link from content div into main div

    The below line opens a selected index from a drop down in a browser window. The form field is in a div called "contents". I need to know the syntax needed to open this selection in another div on the same page called "main". The "_top" location opens the file in a new window. I want to open this on the same page. Do I need javascript for this?
    Code:
    onchange="window.open(this.options[this.selectedIndex].value,'_top')" style="text-align: center">
    Here is all the code for my file:

    Code:

    <html xmlns="http://www.w3.org/1999/xhtml">
    
    <head>
    <meta content="text/html; charset=utf-8" http-equiv="Content-Type" />
    <title>Untitled 1</title>
    <style type="text/css">
    .banner {
    	background-color: #000000;
    	width: 100%;
    	height: 25px;
    }
    .contents {
    	width: 180px;
    	height: 560px;
    	background-color: #0000FF;
    }
    .main {
    	width: 100%;
    	height: 100%;
    	background-color: #006600;
    }
    </style>
    </head>
    
    <body>
    <div id="banner" class="banner">
    </div>
    <div id="contents" class="contents">
    <form action="../">
    &nbsp;&nbsp; <br />
    &nbsp;
    <select onchange="window.open(this.options[this.selectedIndex].value,'_blank')" style="text-align: center">
        <option value="">Choose a destination...</option>

    Why don't you use innerHTML property???

    First of all, yes, you'll need some JavaScript to do this, as you're doing now. Second, I would suggest that you use an <iframe> to hold the contents of the newly opened page.
    Code:
    <script type="text/javascript">
    
     function showPage(theControl) {
      theURL = theControl[selectedIndex].value;
      document.getElementById('myFrame').src = theURL;
     }
    </script>
    <select onchange="showPage(this);" style="text-align: center">
    and then for your DIV:
    Code:
    <div id="main" class="main" style="position: absolute; width: 1148px; height: 564px; z-index: 1; top: 43px; left: 192px">
    <iframe id="myFrame" src="" width="100&#37;" height="100%" frameborder="0" scrolling="yes"></iframe>
    </div>
    You'll probably have to adjust the attributes in the <iframe> tag a bit, but it should be close. And you're likely to have problems getting the "main" <div> to fit nicely on a page with any other content, but...

    I am getting an error in Firebug. It says "selected index is not defined" on line #28. Forgive me in advance for being a beginner here. Here is my current code.

    Code:
    <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
    <html xmlns="http://www.w3.org/1999/xhtml">
    
    <head>
    <meta content="text/html; charset=utf-8" http-equiv="Content-Type" />
    <title>Untitled 1</title>
    <style type="text/css">
    .banner {
    	background-color: #000000;
    	width: 100%;
    	height: 25px;
    }
    .contents {
    	width: 180px;
    	height: 560px;
    	background-color: #0000FF;
    	color: #FFFFFF;
    }
    .main {
    	width: 100%;
    	height: 100%;
    	background-color: #006600;
    }
    </style>
    <script type="text/javascript">
    
     function showPage(theControl) {
      theURL = theControl[selectedIndex].value;
      document.getElementById('myFrame').src = theURL;
     }
    </script>
    </head>
    
    <body>
    <div id="banner" class="banner">

    <div id="contents" class="contents">

    <div id="main" class="main" style="position: absolute; width: 1148px; height: 564px; z-index: 1; top: 43px; left: 192px">
    <iframe id="myFrame" src="" width="100%" height="100%" frameborder="0" scrolling="yes"></iframe>
    </div>
    </body>
    
    </html>

    Sorry. I wrote that on the fly. Try:
    Code:
    <script type="text/javascript">
    
     function showPage(theControl) {
      theURL = theControl[theControl.selectedIndex].value;
      document.getElementById('myFrame').src = theURL;
     }
    </script>
    <select onchange="showPage(this);" style="text-align: center">
