Can I include Javascript/jQuery in a page?

4 Views

I’m extremely new to WordPress, and I’ve offered to help out with a project that uses it.

In a new page I’m creating, I need to use javascript/jQuery to write out the html dynamically – it doesn’t seem to be working? I believe I read there was something special that needed to be done, but I can’t figure out. I tried changing the $ to jQuery, but that didn’t work either.

<script type="text/javascript">
$(document).ready(function(){
     alert('hoi');
     jQuery.ajax({
        type: "GET",
        url: "link-here",
        dataType: "text",
        success: function(data) {alert(CSVToArray(data));}
        error: function(){ alert('error');}
     });
</script>

I have this at the top – the alert isn’t even called. How can I get this working?

Edit It looks like jQuery is loaded for all but the admin page – correct? 

//jQuery Insert From Google
if (!is_admin()) add_action("wp_enqueue_scripts", "my_jquery_enqueue", 11);
function my_jquery_enqueue() {
   wp_deregister_script('jquery');
   wp_register_script('jquery', "http" . ($_SERVER['SERVER_PORT'] == 443 ? "s" : "") . "://ajax.googleapis.com/ajax/libs/jquery/1.7.2/jquery.min.js", false, null);
   wp_enqueue_script('jquery');
}

Edit Two It looks like the code I wrote is being wrapped in <p> tags. This must mean that the script doesn’t belong in the New Page. Where should the code go?

  1. You need to make sure that jQuery is loaded, so that you can use it.

    In functions.php:

    function namespace_enqueue_scripts() {
    if ( is_page( 'slug-of-new-page-you-are-creating' ) )
        wp_enqueue_script('jquery');
}
add_action( 'wp_enqueue_scripts', 'namespace_enqueue_scripts' );
