因此，我一直在开发一个我正在构建的自定义主题，我正试图实现一个基于AJAX的搜索演示。我已经根据一些教程和指南构建了所有内容，但在检查对admin ajax的调用时，它会不断返回400个错误。。。我没有什么想法，希望有人能对这个问题有所了解。

functions.php

function load_search_results(){
$q = $_REQUEST[\'query\'];
$post_type = $_REQUEST[\'post_type\'];

$args = array(
    \'post_type\' => $post_type,
    \'post_status\' => \'publish\',
    \'s\' => $q,
);

$search = new WP_Query($args);

if ($search->have_posts()){
    echo json_encode(\'has posts\');
} else {
    echo json_encode(\'no posts found\');
}

wp_die();
}

add_action(\'wp_ajax_load_search_results\', \'load_search_results\');
add_action(\'wp_ajax_nopriv_load_search_results\', \'load_search_results\');

Enqueueing the scripts in functions.php as well

wp_register_script(\'ajax-search\', THEME_DIR .\'/assets/js/ajax/search.ajax.js\', array(\'jquery\'), \'1.0\', false);
wp_enqueue_script(\'ajax-search\');
wp_localize_script(\'ajax-search\', \'myAjax\', array(\'ajax_url\' =>admin_url(\'admin-ajax.php\')));

search.ajax.js

(function($) {

$(document).on(\'submit\', \'.controls-search\', function(){
    var $form = $(this);
    var $input = $form.find(\'input[name="s"]\');
    var query = $input.val();
    var $content = $(\'.licence\');

    $.ajax({
        type: \'POST\',
        post_type: \'shuffle_licence\',
        url: myAjax.ajax_url,
        data: {
            action: \'load_search_results\',
            query: query
        },
        beforeSend: function(){
            $input.prop(\'disabled\', true);
            $content.addClass(\'loading\')
        },
        succes: function(response){
            $input.prop(\'disabled\', false);
            $content.removeClass(\'loading\');
            $content.html(response);
        },
        dataType: \'html\',
        contentType: \'application/json\',
    });

    return false;

});

}(jQuery))
