WordPress用json\u编码从php向js发帖,并将ID发到div

我使用以下几行代码将帖子作为一个数组来获取,然后通过将带有json\u encode的帖子转换为json将其发送回js,js会要求这样做

function get_feedback() {
    if(isset($_POST['postId'])){
        $postId = $_POST['postId'];
    } 
    $cToken = get_post_meta($postId, 'cToken', true);
    $posts = get_posts(
        array(
        'numberposts' => -1,
        'post_type' => 'post',
        'category' => 'Feedback',
        'meta_key' => 'cToken',
        'meta_value' => $cToken
        )
    );

    echo json_encode($posts);
    wp_die();
}

然后,我尝试将所有帖子id的列表发布到WordPressPage上的一个div中,代码如下

function getFeedback(postId){
    $(".show_company").hide();
    $(".show_feedback").show();
    $.ajax({
        type: "POST",
        url: ajax_object.ajax_url,
        data:{
        action:'get_feedback', 
        postId: postId,
        },
        success:function(response) {
        $("#result").html(response);
        alert(response[0]);


        }
    });
}

但这只是未定义的消息。

从php传递到js的对象如下图所示:

[{"ID":387,"post_author":"9","post_date":"2018-05-17 23:06:35","post_date_gmt":"2018-05-17 23:06:35","post_content":"","post_title":"jitz - grad - 0106","post_excerpt":"","post_status":"publish","comment_status":"open","ping_status":"open","post_password":"","post_name":"jitz-grad-0106","to_ping":"","pinged":"","post_modified":"2018-05-17 23:06:35","post_modified_gmt":"2018-05-17 23:06:35","post_content_filtered":"","post_parent":0,"guid":"http:\/\/localhost\/wp\/jitz-grad-0106\/","menu_order":0,"post_type":"post","post_mime_type":"","comment_count":"0","filter":"raw"},{"ID":386,"post_author":"9","post_date":"2018-05-17 23:06:16","post_date_gmt":"2018-05-17 23:06:16","post_content":"","post_title":"hergott - 0001 - 4","post_excerpt":"","post_status":"publish","comment_status":"open","ping_status":"open","post_password":"","post_name":"hergott-0001-4","to_ping":"","pinged":"","post_modified":"2018-05-17 23:06:16","post_modified_gmt":"2018-05-17 23:06:16","post_content_filtered":"","post_parent":0,"guid":"http:\/\/localhost\/wp\/hergott-0001-4\/","menu_order":0,"post_type":"post","post_mime_type":"","comment_count":"0","filter":"raw"}]

所以它基本上是一个包含两个对象的对象,这两个对象都是post。我如何在这里处理帖子的属性?
