Exclamation How to know that the iframe is empty!
I create a form that use <iframe> and I want to know whether the user input the data in my <iframe> or not. If he doesn't input data, I want it to alert the error message. But I don't know how to do.

Help me, please!

What do you mean 'I create a form that use <iframe>'? I don't follow.

Can we see your code please?

It should be quite simple for a script to validate, provided the page in
