JavaScript Undefined Variable Error In IE6

Question

I have a PHP file in that I have declared a JavaScript variable.

I will get that variable value while I am opening the page directly by type the my URL on IE6.

But the problem is if I am clicking a href link to open the same page got particular variable undefined error on IE6.

After undefined error if I refresh the same page I can get the variable value.

I am using script tag to load the page

as like

<script language="javascript" src="commonjs.php"></script>

In my commonjs.php

<?  include_once("myconffile.php");  ?>
var myvars = <?=$varConfValue['domainname']?>

Please help me on this.

Are you sure short_open_tag is enabled? Afaik, by default it is not. — Felix Kling

You should add quotes around the value of myvars if it is a string.

<?  include_once("myconffile.php");  ?>
 var myvars = "<?=$varConfValue['domainname']?>"

Otherwise you get something like var myvars = localhost. Javascript then looks for a variable named localhost, which is undefined.
