Iframe without src attribute - javascript vs about:blank vs #
Raw
Iframe_without_src
javascript:false:
IE10 and FF (checked in v23 in Linux) will show 'false' as content.
javascript:void(0) && javascript:;:
IE will show 'cannot display the webpage' error in the iframe. Also, when setting the src from a valid url to javascript:void(0), the page will not get blank.
about:blank:
Works in all browsers but IE 9 sends an request to the server with path "null". Still the best bet IMO
