I know there are a lot of questions regarding this issue, but I can't figure out mine here. I'm trying to load the whole jQuery UI ( Actually I need only the Slider ) and I successed. This is my enqueing which is working:
wp_enqueue_script('jquery-google-lib', 'https://ajax.googleapis.com/ajax/libs/jquery/2.1.4/jquery.min.js', array('jquery'), '2.1.4'); wp_enqueue_script('jquery-ui', 'https://ajax.googleapis.com/ajax/libs/jqueryui/1.11.4/jquery-ui.min.js', array('jquery'), '1.11.4'); wp_enqueue_style('jquery-ui-css-google-lib', 'https://ajax.googleapis.com/ajax/libs/jqueryui/1.11.4/themes/smoothness/jquery-ui.css');
And this is the working various. When I check my head section, I can see I load jquery twice. I read the codex and says that WP loads jquery and jquery UI by default. Why I cannot use them and load them twice? When I remove the jquery enqueueing, jquery UI is not loading. Is it a good practice to load jquery from external sources? Why the wordpress jquery is in version 1.4.1 and google's 2.1.4? When there are these libraries loaded, why can't I use them in the front end? I got quite confused about this.
