base_url() codeigniter 3.0.4 duplicate in URL with javascript

your script is in a file with extension php or js ?

because <?php ... ?> can work only on php files

for me, before insert all my JS scripts in my template, i write this little code

PHP Code:

<script>
    var BASE_URL = "<?php echo base_url(); ?>";
<script>

<script type="text/javascript" src="file1.js" />
<script type="text/javascript" src="file2.js" />
<script type="text/javascript" src="file3.js" />
..... 


BASE_URL will be available in all your JS files
