I've been trying to fix the script that used to work on IE, which auto fills the form that has many duplicated datas that needed to fill in every time,

but recently the company I work for, they changed their internal webpage to Edge only for security reason, and my script don't work anymore because newer browser does not allow to.

it's something like this:

window.frames[1].frames[2].document.getElementById("some_textbox").value = "data"

It is nested framesets and Edge does not allow me to get the child frame and its elements by this way, is there any go around solution?
