**编辑：**其他脚本的变体似乎也不起作用，wp_enqueue_media（）运行正常，但似乎不包括包含wp.media的脚本。

我试图在自定义插件中使用Wordpress Media Uploader，但不断得到以下错误：

TypeError: undefined is not an object (evaluating 'wp.media.frames')

字符串
我的Javascript代码：

jQuery(document).ready(function(){

  var mediaUploader;

  jQuery('#upload-button').click(function(e) {
    e.preventDefault();
    // If the uploader object has already been created, reopen the dialog
      if (mediaUploader) {
      mediaUploader.open();
      return;
    }
    // Extend the wp.media object
    mediaUploader = wp.media.frames.file_frame = wp.media({
        title: 'Choose Image',
      button: {
      text: 'Choose Image'
    }, multiple: false });

    // When a file is selected, grab the URL and set it as the text field's value
    mediaUploader.on('select', function() {
      var attachment = mediaUploader.state().get('selection').first().toJSON();
      jQuery('#logo').val(attachment.url);
    });
    // Open the uploader dialog
    mediaUploader.open();
  });

});

.js文件注册如下：

/* Add the media uploader script */
  function my_media_lib_uploader_enqueue() {
    wp_enqueue_media();
    wp_register_script( 'media-lib-uploader-js', plugins_url( 'media-lib-uploader.js' , __FILE__ ), array('jquery') );
    wp_enqueue_script( 'media-lib-uploader-js' );
  }
  add_action('admin_enqueue_scripts', 'my_media_lib_uploader_enqueue');
