.htaccess要求我多退出一个目录

I have got these files index.php and user.php and this htacess RewriteRule users/([^/]+)$ index.php?user=$1 [L,QSA] now this changes my website to domain.com/users/username and if i have a file in the same directory as user.php it requires me to add ../ because it thinks that users is a folder name.For example

<script src="js/user.js"></script>

becomes

<script src="../js/user.js"></script>
