Undefined Search [DOM]

RESOLVED
I fixed this by using json, instead of arrays.

Hello!

This is kind of javascript and PHP - but the problem has to do with JS.

I'm creating a suggest search, and a problem I'm facing is that I'm trying to get a variable form another file - and for some reason the javascript isn't gettnig it. =/

Here's my javascript/html:

HTML Code:

<html>
	<head>
	  <title>Suggest Search</title>
	  <script type="text/javascript">
	    var check, refresh;
		var headEl = document.getElementsByTagName("head")[0];
		var suggest = function(me){
		  // Getting Javascript //
		  if(check != true){
		    check = true;
		  } else {
		    headEl.removeChild(refresh);
		  }
		  refresh = document.createElement("script");
		  refresh.type = "text/javascript";
		  refresh.src = "info.php?search="+me.value;
		  headEl.insertBefore(refresh, document.getElementsByTagName('script')[0]);
		  // Displaying suggestions //
		  alert(search.length);
		};
	  </script>
	</head>
	<body>
	  <input type="text" onkeydown="suggest(this);" onkeyup="suggest(this);" onchange="suggest(this);" onmouseover="suggest(this);" onclick="suggest(this);"/>
	</body>
</html>

And here's my PHP/javascript:

PHP Code:


<?php

header("Content-type: text/javascript");

if(!isset($_GET['search'])){ echo 'var search = new Array()'; }

mysql_connect("localhost", "root", "") or die(mysql_error());

mysql_select_db("general") or die(mysql_error());



$search = mysql_real_escape_string($_GET['search']);

$query = mysql_query("SELECT name FROM suggest WHERE name LIKE '%{$search}%'") or die(mysql_error());

$name = array();

while($row = mysql_fetch_assoc($query)){

  $name[] = $row['name'];

}

$js_array = 'var search = new Array(';

foreach($name as $key => $value){

  $js_array .= ($key == count($name)-1) ? "'$value'" : "'$value', ";

}

$js_array.= ');';

echo $js_array;

?>

I'm getting this error:

If it is needed really badly - I'd be happy to post it online.

Thanks! Nile
