jquery and codeigniter

Answer 1

Place jquery.js in your website root and use:

<script type="text/javascript" src="/jquery.js"></script>

If you want to put it say in a js folder, place the folder in root and do:

<script type="text/javascript" src="/js/jquery.js"></script>

Or you can try this:

<script type="text/javascript" src="<?=base_url();?>js/jquery.js"></script>

as described here

Answer 2

Also consider that if you use Codeigniter's default .htaccess configuration suggested in the Codeigniter URLs page:

RewriteEngine on
RewriteCond $1 !^(index\.php|images|robots\.txt)
RewriteRule ^(.*)$ /index.php/$1 [L]

you won't be able to access a jquery.js file as a request for that resource will be rewritten to index.php; if this is a case you have to add that file as an exception:

RewriteCond $1 !^(index\.php|images|jquery\.js|robots\.txt)
