Can you change innerHTML of IFRAME?

IFRAME tag in HTML doesn't has innerHTML attribute/property which could have been used to change the content of IFRAME without changing "SRC".

If your IFrame is defined like : <iframe name='myIFRAME' > </iframe>

In your javascript function you can change innerHTML of IFRAME using:

document.myIFRAME.document.body.innerHTML = 'yourHTML';

similarly you can change innerHTML of components inside the IFRAME:

document.myIFRAME.document.getElementById('your_element_id').innerHTML = 'yourHTML';
