I have an Iframe with media(image) as content, when clicking on the image and pressing back space the image disappear (as display) but the iframe content (shown in java) is not empty, the image still exists.

in my code , I have button browse with upload = true , and on upload i set the media in the iframe content.

how can i prevent erasing the image with backspace, or how can i catch the event on 'backspace'
