How can I hook into an existing wp.media object and grab the attachment ID when the "Set Featured Image" button is clicked?
如何在单击“设置特色图像”按钮时挂钩到现有的wp.media对象并获取附件ID?
The wp.media tutorials I've been looking at all seem to start by creating a new wp.media frame, but I just want to listen for events coming from an existing one (rendered by wp_editor() function), particularly the "Set Featured Image" event.
我一直在看的wp.media教程似乎都是从创建一个新的wp.media框架开始的,但我只是想监听来自现有的事件(由wp_editor()函数呈现),特别是“Set”特色图片“活动。

Try using the wp.media.featuredImage object, and more specifically its frame() and get() methods:
尝试使用wp.media.featuredImage对象,更具体地说是它的frame()和get()方法:
// on featured image selection...
wp.media.featuredImage.frame().on( 'select', function(){
// ...get the attachment ID
var attachment_id = wp.media.featuredImage.get();
console.log( attachment_id );
});
