redirect to javascript function

[gilgalbiblewhee]

Is there a way to redirect a page to a JavaScript function:

PHP Code:

<?php
if($_GET["goto"]!==""){
    echo $_GET["goto"];
    echo "<input name=\"\" id=\"gotolink\"type=\"hidden\" value=\"".$_GET["goto"]."\" />\n";
    //header("Location: index.php");
    echo "<meta http-equiv='Refresh' content='0; url= \"JavaScript: gotolink();\"' />\n";
    //echo "<meta http-equiv='Refresh' content='0; url= ../index.php' />\n";
}

?>

The point of this is let's say the url is this:
http://mywebsite.com/flashclips/hock...ips/hockey.php

I want the goto to be grabbed by the get method redirect to the index and using AJAX I want this extension:
goto=flashclips/hockey.php

to be appearing in the "main" div tag.

function createRequest(){
	var req = false;
	try {
		req = new ActiveXObject('Msxml2.XMLHTTP');
	} catch (e2) {
	try {
		req = new ActiveXObject('Microsoft.XMLHTTP');
	} catch (e3) {
		try {
			req = new XMLHttpRequest();
		} catch (e1) {
			req = false;
			}
		}
	}
	return req;
}

/*****************************************************************/
function getit(aid, aurl){
	var req = createRequest();
	if(req){
		req.onreadystatechange = function(){
			var c = document.getElementById(aid);
			if(req.readyState){
				if(req.readyState == 4){
					if(req.status == 200){
						c.innerHTML = req.responseText;
					}
				}
			}
		}
	req.open('GET', aurl, true);
	req.setRequestHeader("Content-Type","application/x-www-form-urlencoded");
	req.send(null);
	}
}
function gotolink(){
       getit('maindiv','flashclips/hockey.php');
	location.href = "../index.php";
}
