How to add jQuery script to an individual page?

1 Views

I have this code which I want to add into a specific page of mine. I don’t want to create a file for it and then include etc (though do tell if that would be the only way). Also I don’t want it to be in the header as it would be included in all pages. The code is: 

<script type="text/javascript">
$(function () {
    $('input[name=done]:radio').click(function () {
        if ($(this).val() === "Yes") {
            $('#p-days').show();
        } else {
            $('#p-days').hide();
        }
    });
    $('input[name=already-b]:radio').click(function () {
        if ($(this).val() === "Yes") {
            $('#div-name').show();
        } else {
            $('#div-name').hide();
        }
    });
});
</script>

I added this in the editor by selecting the Text (not in Visual mode.) But it is not working. Any ideas what I’m doing wrong?

  1. Although @s_ha_dum is correct you WILL need to use jQuery no conflict within WordPress the original question is left unanswered.

    I have this code which I want to add into a specific page of mine.

    There are a couple of ways to do this

    Based on Page name/slug WordPress in theme’s functions.php

    This method uses the WordPress hook wp_enqueue_scripts

    1. Create a new js file for your script my-nifty-custom.js

    2. In your functions.php add the following

      /* Enqueue scripts (and related stylesheets) */
    add_action( 'wp_enqueue_scripts', 'my_nifty_scripts' );
/**
 * Registers scripts for the theme and enqueue those used site wide.
 *
 * @since 0.1.0.
 */

function my_nifty_scripts() {
    wp_register_script('my-nifty-custom', get_stylesheet_directory_uri() . '/js/my-nifty-custom.js', false, null, true);
if(is_page('page-slug-here')){
    wp_enqueue_script('my-nifty-custom'); 
}}

    Note if you are using a child-theme or want to do it morebetter wrap the whole thing in after_setup_theme ie:

    add_action( 'after_setup_theme', 'nifty_theme_setup' );
function nifty_theme_setup() {
// script function and other functions that should happen after the initial theme setup
}

    Based on Body Class (DOM-based Routing)

    This is a little bit more complicated. Luckily Paul Irish wrote a fantastic blog about it here: http://www.paulirish.com/2009/markup-based-unobtrusive-comprehensive-dom-ready-execution/

    If you use this method it will get your custom JS on a per page basis based on the Body Class. For Example <body class="nifty">

    Then you would use:

    //clip 
 nifty : {
    init     : function(){ //custom script goes here }
  }
//clip

    The only problem with this is the page must have the body class you are calling. For this WordPress has the function body_class

    add_filter('body_class','nifty_class_names');
function nifty_class_names($classes) {
    if(is_page('page-slug-here')){
        $classes[] = 'nifty';
    }

    return $classes;
}

    So which method should you use?

    I recommend a combination of both. Create one JavaScript file that uses Paul’s method. Then use wp_enqueue_scripts to call that method.

    Lazy header.php method

    Lastly there IS always the lazy way (which I don’t recommend but am noting just for reference.

    In your header.php you can do:

     <?php if(is_page('page-slug-here')){
           echo ('<script type="text/javascript" src="'. get_stylesheet_directory_uri() . '/js/my-nifty-custom.js"> </script>'); 
        } ?>

  2. WordPress loads jQuery in “No Conflict” mode. The “$” alias doesn’t work. Use the full “jQuery”– jQuery.$.ajax({... or wrap your script like the example from the jQuery docs…

    (function($) { 
  $(function() {
    // more code using $ as alias to jQuery
  });
})(jQuery);

    There is information about this in the Codex as well.
