JQuery removes the img element of the specified id from the div with the specified id, jquerydiv

During project creation, I dynamically Add the img element to the div with the specified id through jQuery, and then click the delete button to delete the img with the specified id

$ ("# Showimg"). find ("img [id = '" + file. id + "']"). remove ();

Showimg is the div id, file. id is the id of the img. I directly use $ ("#" + file. id ). remove () cannot delete this img. I don't know why. I just deleted it using the above.

If any hero knows why, let me know. Thank you!
