I just want to create an alert box when a page with a post is reloaded.

<script type="text/javascript">

And here is the php code i wrote to load the js.

function alert_js(){
   wp_enqueue_script('likeButton', plugins_url( '/alert.js', __FILE__ ));
add_action('the_post', 'alert_js');

I’m sure that it successfully finds the script in right place(I checked the page source.). But somehow it acts like there is no javascript included. What I’m missing there?
