Is it possible to use JS to alter src to data-src on iframe?

[uglyeoin]

If I want to use this on an iFrame I need to manually rename them all from src to data-src. This should probably be done on document load.

Blazy doesn't work on document load does it? Is there a solution to this?

@uglyeoin I would do it in the html so you initialize the markup with data-src. But answering you question, yes its possible buy you need to do it as early as possible

But it is not HTML this is a CMS, so things are load dynamically. I'll see if there is a way to do it earlier in the process.
