JQuery plugin stopped working Error: jQuery(“#slider”).easySlider is not a function [closed]

Question

This plugin stopped working without modification. It was working last week. I've spent the last week working on something else, came back to it and not working. Any suggestions as to why?

<?php wp_enqueue_script("jquery"); ?>
<?php
if ( is_page('home') ) { 
   // If it's the home page, we want the slider, otherwise don't bother
   wp_register_script('easyslider',
       get_bloginfo('template_directory') . '/js/easySlider1.7.js');
   // enqueue the script
   wp_enqueue_script('easyslider');
}
?>
<?php
if ( is_page('our-services') ) { 
   // If it's the 'our services' page, we want the capty plug-in, otherwise don't bother
   wp_register_script('capty',
       get_bloginfo('template_directory') . '/js/jquery.capty.min.js');
   // enqueue the script
   wp_enqueue_script('capty');
}
?>
<?php wp_head();?>

<?php if ( is_front_page() ) { ?>
<script type="text/javascript">
    jQuery(document).ready(function($){ 
        jQuery("#slider").easySlider({
            auto: true, 
            continuous: true,
            numeric: true
        });
    }); 
</script>
<?php }; ?>
<?php if ( is_page('our-services') ) { ?>
<script type="text/javascript">
    jQuery(document).ready(function($){
        jQuery('#desktop,#advice,#infrastructure,#web').capty({
        animation: 'slide',
        speed:     400
        });
    });
</script>
<?php }; ?>

Ok, thanks for all the answers. It seems the problem was with another plug-in; I noticed that there was a new version of that plug-in available, installed that, and now everything is fine.

Answer 1

use if ( is_front_page() ) instead of if (is_page('home')) at the top.

Answer 2

Tony, you should use an action to enqueue your scripts. E.g. add something like this to your functions.php:

function register_script() {
   wp_register_script('capty',
       get_bloginfo('template_directory') . '/js/jquery.capty.min.js');
   // enqueue the script
   wp_enqueue_script('capty');
}
add_action( 'init','register_script');

If you want to load the scripts conditionally, you could take a look at http://scribu.net/wordpress/optimal-script-loading.html (article itself plus comments). Cheers, Peter

Answer 3

I had a similar problem in a friend's website. In my case it was because jQuery was being reloaded after the plugin, which reseted jQuery. Try to look in your source (especially in your theme's footer) if there's any plugin loading jQuery a second time.
