Question

How to refer to a component inside an IFRAME is showed in this reply. It works under the assumption that there’s only one IFRAME (or that we are certain that the zero-th will suffice). However, I wonder how to identify the actual IFRAME I’d like to poke.

I need the syntax for changing:

window.frames[0].document. + my stuff

into something like:

window.frames["theIdOfMyIFrame"].document. + my stuff

but I can’t get it right.

Answer 1

1. I would avoid using window.frames. (Might be due to the lack of experience with them.)
2. When a reply on the net is on form something[0], be cautious. Bad coding style, probably.
3. The reference to your theIdOfMyIFrame should be used.
4. The inner document is right under contentDocument.

You can refer to the embedded components like this.

document.getElementById("theIdOfMyIFrame")
  .contentDocument.getElementById("controlIdInTheembeddedPage")
    .value = "Christophe has eyes for details!";
