How does the wxParser-plugin Mini Program rich text plug-in monitor the completion of rich text loading?

how do I load a finished monitor on rich text content? In order to obtain the height of the wxparser tag and so on. At present, images are the most used, but bindload is not found in the image tag, so how do you monitor the completion of image loading?
