Here's an interesting one. A HTML page is calling a javascript which opens a new window. From that opened window, I can then issue something like this:

window.opener.Message.To.value=lcMessageMark

This works fine as long as the form name and the field name remains the same. And, that will work as long as the form name is Message and that the field name is To.

Now, from the original HTML page, I have several calls to this javascript function to store the returned value in various fields. So, for example, before calling the function, I may issue something like this to store the form name and the field name.

document.MyForm.Form.value='MyForm'
document.MyForm.Field.value='NoMember'
GoGetValue()

function GoGetValue()
{
   window.open("MyUrl");
}

Then, I need a mecanism from the opened window to dynamically assign the returned value in the MyForm.NoMember field.

So, I would need something like this:

lcForm=window.opener.MyForm.Form.value
lcField=window.opener.MyForm.Field.value
window.opener.&lcForm.&lcField.value=lcMessageMark

But, of course, that syntax is not working. How can I achieve that?
