I must be doing something really stupid here, but I've been beating my head against it for a while and I haven't been able to find what's wrong.
On this page: http://ww2.accudata.com/
I'm trying to implement jCarousel, and I keep getting this error:
jQuery("#mycarousel").jcarousel is not a function
Here's what I have in my header:
<script type="text/javascript" src="https://ajax.googleapis.com/ajax/libs/jquery/1.6.4/jquery.min.js?ver=1.6.4"></script>
<script type="text/javascript" src="<?php bloginfo('template_directory'); ?>/js/jquery.jcarousel.min.js"></script>
<link rel="stylesheet" type="text/css" href="<?php bloginfo('template_directory'); ?>/js/skins/carousel/skin.css" />
<script type="text/javascript">
jQuery(document).ready(function() {
jQuery('#mycarousel').jcarousel({
});
});
</script>
So as far as I can tell, I'm loading all of the scripts in the correct order, and I have verified that they are all there. So why does it say it's not a function?
jQuery is the most popular library on the web today. It's a library of JavaScript functions that make it easy for webpage developers to do common tasks-- like manipulating the webpage, responding to user events, getting data from their servers, building effects and animations, and much more.
Though JavaScript is the basic language from which jQuery has evolved, jQuery makes event handling, DOM manipulation, Ajax calls much easier than JavaScript. jQuery also allows us to add animated effects on our web page which takes a lot of pain and lines of code with JavaScript.
jQuery is a JavaScript Library. jQuery greatly simplifies JavaScript programming.
Bootstrap 5 is designed to be used without jQuery, but it's still possible to use our components with jQuery. If Bootstrap detects jQuery in the window object it'll add all of our components in jQuery's plugin system; this means you'll be able to do $('[data-bs-toggle="tooltip"]'). tooltip() to enable tooltips.
On line 39, you are reloading jQuery, which overwrites the jQuery object, removing the .jcarousel
function. Make sure you are loading jQuery only once.
<script type="text/javascript" src="https://ajax.googleapis.com/ajax/libs/jquery/1.6.4/jquery.min.js?ver=1.6.4"></script>
<script type="text/javascript" src="http://ww2.accudata.com/wp-content/themes/accudata/js/jquery.jcarousel.min.js"></script>
<link rel="stylesheet" type="text/css" href="http://ww2.accudata.com/wp-content/themes/accudata/js/skins/carousel/skin.css" />
<script type="text/javascript">
jQuery(document).ready(function() {
jQuery('#mycarousel').jcarousel({ //Would work if you called it here, but it gets deferred until the DOM is loaded
});
});
</script>
...
<script type='text/javascript' src='https://ajax.googleapis.com/ajax/libs/jquery/1.6.4/jquery.min.js?ver=1.6.4'></script>
<!-- This gets loaded after you load the plugin, overwriting the jQuery object -->
The error you're seeing basically means:
"we tried looking for the jcarousel function, and couldn't find it."
Open the page source and see what HTML is being rendered. Are you paths to the .js files correct and what you expect? Most of the times this is the cause of these types of problems.
So once you're sure that your references to the .js files are correct, try something like this:
<script type="text/javascript">
$(document).ready(function() {
$('#mycarousel').jcarousel({
//Settings here.
});
});
</script>
