WordPress path url in js script file

4 Views

I added custom script: 

wp_enqueue_script('functions', get_bloginfo('template_url') . '/js/functions.js', 'search', null, false);

It works great, except in the functions.js I have:

Reset.style.background = "url('../images/searchfield_clear.png') no-repeat top left";

This used to work before, until I changed to pretty permalinks and .htaccess

The folder hierarchy is like:

themename/js themename/images (the images and js folder are in themename folder)

I tried ../images – ./image – /images

Normally it should go back 1 level wherever the js file is located….

I don’t want to use full path.

Is there another way that WordPress can recognize in the javascript file to have the correct path?

Currently I am just confused what I am doing wrong.

  1. According to the WordPress documentation, you should use wp_localize_script() in your functions.php file. This will create a Javascript Object in the header, which will be available to your scripts at runtime.

    See Codex

    Example:

    <?php wp_localize_script('mylib', 'WPURLS', array( 'siteurl' => get_option('siteurl') )); ?>

    To access this variable within in Javascript, you would simply do:

    <script type="text/javascript">
    var url = WPURLS.siteurl;
</script>

  2. You could avoid hardcoding the full path by setting a JS variable in the header of your template, before wp_head() is called, holding the template URL. Like:

    <script type="text/javascript">
var templateUrl = '<?= get_bloginfo("template_url"); ?>';
</script>

    And use that variable to set the background (I realize you know how to do this, I only include these details in case they helps others):

    Reset.style.background = " url('"+templateUrl+"/images/searchfield_clear.png') ";

  3.     wp_register_script('custom-js',WP_PLUGIN_URL.'/PLUGIN_NAME/js/custom.js',array(),NULL,true);
    wp_enqueue_script('custom-js');

    $wnm_custom = array( 'template_url' => get_bloginfo('template_url') );
    wp_localize_script( 'custom-js', 'wnm_custom', $wnm_custom );

    and in custom.js

    alert(wnm_custom.template_url);

  4. If the javascript file is loaded from the admin dashboard, this javascript function will give you the root of your WordPress installation. I use this a lot when I’m building plugins that need to make ajax requests from the admin dashboard.

    function getHomeUrl() {
  var href = window.location.href;
  var index = href.indexOf('/wp-admin');
  var homeUrl = href.substring(0, index);
  return homeUrl;
}

  5. For users working with the Genesis framework.

    Add the following to your child theme functions.php

    add_action( 'genesis_before', 'script_urls' );

function script_urls() {
?>
    <script type="text/javascript">
     var stylesheetDir = '<?= get_bloginfo("stylesheet_directory"); ?>';
    </script>
<?php
}

    And use that variable to set the relative url in your script. For example:

    Reset.style.background = " url('"+stylesheetDir+"/images/searchfield_clear.png') ";
