What should i use Iframe or Frameset?

Question

I am creating a page wherein there will be a text box , a button and a frame .
Wireframe:

Now, i am having two option,
1. I will keep text box [ it is used for URL ] and Button in a Div and will use Iframe to show the content of url.
2. I will use frameset, the first frame will have text box and Button and the next frame will be used to show the content of url.

What do you suggest which approach should i follow? I guess both of them will work.

Answer 1

I'll suggest you first one. Because permission between frames in frameset would be a problem sometimes.

Answer 2

There's no technical reason to choose either. Both will work. I'd go with the second one. There are still a few use cases for frames, and this is definitely one.
