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

<script type="text/javascript">
window.alert("alert");
</script>

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

function alert_js(){
   wp_enqueue_script('alert_js', 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?

  • This is more of a question, then an answer, however… Do you have script tags in your JavaScript file? – whakawaehere Apr 10 '17 at 21:47

I think you are missing the trigger... your javascript should be something like this in order for it to trigger when the page is loaded:

$( document ).ready(function() {
    alert( "ready!" );
});

  • Also, you should use wp_enqueue_scripts hook to load stylesheets and scripts as best practice. Mark this answer as best answer if solved your problem. – Caio Mar Apr 10 '17 at 22:12
