HyperCell (?) Link - Parsing Referrer + Cookie

    Hi, I'm really no expert. I don't even know if this is called hypercell.
    But this seems like a simple thing, which I'm sure will be a piece of cake to the gurus out there.

    I'm using this particular javascript technique whereby when a cell in a table has "onmouseover" the cell changes color, and when the cell has "onmouseout" it goes to a link.

    A simple sample is as attached. Or basically the whole sample script is like this:
    <html>


<head>
<meta http-equiv="Content-Language" content="en-us">
<script type="text/javascript">
  function link1(){
    window.location.href="http://www.google.com/"; 
  } 
</script>

<script type="text/javascript">
  function link2(){
    window.location.href="http://www.yahoo.com/"; 
  } 
</script>
</head>


<body>
<center>

<table border="1" width="200" cellspacing="0" cellpadding="0" height="100">
	<tr>
		<td onmouseover="this.style.background='#F1F7FA';this.style.cursor='pointer'" onmouseout="this.style.background='white';" onclick="link1()" width="50%" align="center">
		<p align="center">Link to Google</td>
		<td width="50%" align="center">
		&nbsp;</td>
	</tr>
	<tr>
		<td onmouseover="this.style.background='#F1F7FA';this.style.cursor='pointer'" onmouseout="this.style.background='white';" onclick="link2()" width="50%" align="center">
		Link to Yahoo!</td>
		<td width="50%" align="center">
		&nbsp;</td>
	</tr>
</table>

</center>
</body>


</html>
    Code (markup):
    This script works great. Just that:

    1. How do we make the links open in a new window?
    2. When we click on the cells, how do we parse the REFERRER info as well as the cookie info? I find that using this script just treats the click as a new click to the link, but I'm sure that some info can be parsed.
    .

    1. use window.open("http://google.com") instead of window.location.href
    2. what do u want to do with cookie? To get? no problems:
    	function readCookie(name)
	{
	  var cookieValue = "";
	  var search = name + "=";
	  if(document.cookie.length > 0)
	  { 
		offset = document.cookie.indexOf(search);
		if (offset != -1)
		{ 
		  offset += search.length;
		  end = document.cookie.indexOf(";", offset);
		  if (end == -1) end = document.cookie.length;
		  cookieValue = unescape(document.cookie.substring(offset, end))
		}
	  }
	  return cookieValue;
}
    Code (markup):
    and then do with cookieValue what u want. How to get REFERRER info i dont know

    Hey So1, thx alot for your help.
    Just before I read your post, I actually tried window.open.
    And the funny thing is, my initial method works, just that I had some settings wrong.
    How silly of me, searching all over for information and waiting for help.
    Guess I gotta be really careful next time.
    Thanks anyway.

    About REFERRER... I dont cnow what u use as server-side promgramming language (i use PHP).
    U can generate JavaScript on server.

    Just an exmple on PHP:
    print "<script type='text/javascript'>var referer = " . $_SERVER['HTTP_REFERER'] . "</script>";
    If user get this page via clicking link (<a href="our_page">). $_SERVER['HTTP_REFERER'] defined, otherwise u'll get notice message of PHP-interpretator. Use if(isset($_SERVER['HTTP_REFERER'])) condition.
