Now that is pretty cool. <a href="http://codex.wordpress.org/Conditional_Tags#Any_Page_Containing_Posts" rel="nofollow">http://codex.wordpress.org/Conditional_Tags#Any_Page_Containing_Posts</a> </p> http://themeshaper.com/forums/topic/load-javascript-only-on-specific-page#post-15218 Mon, 30 Aug 2010 17:41:44 +0000 Thompson 15218@http://themeshaper.com/forums/ <p>Thank you tarpontech. template_redirect seems to work too. I saved that trick in case I need it in the future. It turns out that I think the problem with my code was that the if statement needs to be on the wp_register_script that specifies the URL of the new script. And since wp_enqueue_script can be in place of wp_register_script (at least from my reading), I ended up using just enqueue to try to keep it as short as possible. So this is what I ended up with:</p> <p>// Remove plugin JS and add my JS only where needed<br /> function childtheme_deregister_script() {<br /> wp_deregister_script( 'pluginJS' );<br /> if ( is_single('26') ) {<br /> wp_enqueue_script( 'pluginJS', ("/wp-content/themes/thematic-child/form.js"), false,'1.0');<br /> }<br /> }<br /> add_action( 'wp_print_scripts', 'childtheme_deregister_script', 100 );</p> <p>Thanks. </p> http://themeshaper.com/forums/topic/load-javascript-only-on-specific-page#post-15214 Mon, 30 Aug 2010 16:12:53 +0000 tarpontech 15214@http://themeshaper.com/forums/ <p>I'm not 100%, but I've seen a few times where if things don't fire on specified pages, it's (based on something I learned from Gene) because your script isn't being called early enough in Wordpress's order of operation. Try swapping 'wp_print_scripts' with 'template_redirect'.<br /> As this is the point when wordpress makes the decision as to what page to load, this may be the right place to stick a page-specific script like this. </p> http://themeshaper.com/forums/topic/load-javascript-only-on-specific-page#post-15206 Mon, 30 Aug 2010 05:32:23 +0000 Thompson 15206@http://themeshaper.com/forums/ <p>Hi all, Does anybody know how to load JS only on a specific page?</p> <p> function childtheme_deregister_script() {<br /> wp_deregister_script( 'pluginJS' );<br /> wp_register_script( 'pluginJS', ("http://www.domain.com/wp-content/themes/thematic-child/form.js"), false);<br /> if ( is_home() ) {<br /> wp_enqueue_script( 'pluginJS' );<br /> }<br /> }<br /> add_action( 'wp_print_scripts', 'childtheme_deregister_script', 100 );</p> <p>This works to the extent that it removes the plugin's original javascript ('pluginJS') and instead loads mine from the URL. But it still does not load on only the specified pages. Any help please? </p>
