From your code

Im not sure that your this.form.details valid or not.

IF it's valid, have a look in window.opener.document.getElementById('details').value = selvalue;

I can't found an input's id contain details I'm just found only id=sku1 (recommend you to add " like id="sku1").

And from your id it's hardcode. Let's see how to do with dynamic when a child has callback to update some textbox on the parent Take a look at here.

First page.

 choose
 choose

Look in function choose I'm sent an id of textbox to the popup window (don't forget to add dummy data at last of URL param like &dummy=avoid#)

Popup Page

Car 

Food 

I have add function getUrlVars for get URL param that the parent has pass to child.

Okay, when select data in the popup, for this case it's will call function goSelect

In that function will get URL param to sent back.

And when you need to sent back to the parent just use window.opener and the name of function like window.opener.callFromDialog

By fully is window.opener.callFromDialog(idFromCallPage,data);

Or if you want to use window.opener.document.getElementById(idFromCallPage).value = data; It's ok too.
