Detailed Description

Contains the implementation of the DeferIframeFilter which defers the iframe using JsDeferDisabledJavascriptFilter. This filter should be called before JsDeferDisabledJavascriptFilter. This filter renames all the iframe tags to pagespeed_iframe and add a script which converts pagespeed_iframe back to iframe and the added script is deferred by JsDeferDisabledJavascriptFilter.

Html input to this filter looks like: <html> <head> </head> <body> <iframe src="1.html"></iframe> </body> </html>

Output for the above html will be: <html> <head> </head> <body> <script> defer_iframe script. </script> <pagespeed_iframe src="1.html"> <script> Script which changes above pagespeed_iframe tag name to iframe. </script> </pagespeed_iframe> </body> </html>

Above script which converts pagespeed_iframe to iframe will be deferred by JsDeferDisabledJavascriptFilter, hence loading of iframe is also deferred.
