View Full Version : Parent page executing ExtJS function on iFrame

2 Aug 2014, 9:17 AM
I relatively new to ExtJS so please excuse me if this is a newbie question. A project I am working on has an ExtJS application embedded into our main application (non-ExtJS) and I am looking for a way for the parent to call an ExtJS function on the child iFrame. I tried creating a singleton with an alias, then referencing the alias in my calling javascript but that didn't work.

The other alternative I think would be to use deep links, but I cannot refresh the iFrame as it would lose the work that was done. Also this is ExtJS 4.2.

Thanks in advance for any suggestions.

Are your frames on the same domain? Otherwise this is not really possible (only using HTML5's message API).
