Usage
JavaScript
nebula.autocompleteSearch(element, types)
Parameters
element
(Required) (Object (or String)) The jQuery object (or selector) of the search input field
Default: None
types
(Optional) (String) A comma-separated string of post types to include
Default: 'any'
Examples
Include only posts and pages in search.
JavaScript
nebula.loadJS(nebula.site.resources.scripts.nebula_jquery_ui, 'jquery-ui').then(function(){ //Ensure jQuery-UI JS is loaded
jQuery('#example-input').on('keyup paste', function(){ //Add the listener
nebula.autocompleteSearch(jQuery(this), 'post,page');
});
});
nebula.loadCSS(nebula.site.resources.styles.nebula_jquery_ui); //Load the jQuery-UI CSS too
Search all post types by simply using the WordPress core "s" class.
HTML
<input class="s" type="text" placeholder="Search this site..." />
Customize the post types in an HTML form without needing to re-write any JavaScript
HTML
<input class="search" type="text" data-types="post,page" />
Additional Notes
For an easier implementation, you could simply add the class s to the search input. See autocompleteSearchListeners().
On keypress or paste, this function triggers nebula_autocomplete_search_start.
On autocomplete success, nebula_autocomplete_search_success is triggered.
When search results are available, nebula_autocomplete_search_results is triggered, otherwise nebula_autocomplete_search_no_results is triggered if no results are available.
On AJAX error, this function triggers nebula_autocomplete_search_error.
