How to use _IEFormElementRadioSelect without finding a Form

I need this script to work, but without using _IEFormGetObjByName or _IEFormGetCollection, and while knowing only the Name of the radio buttons.

$oIE = _开发者_运维技巧IE_Example ("form")
$oDoc = _IEDocGetObj($oIE)
$oArray = $oDoc.getElementsByTagName ("input")
For $element In $oArray
If $element.Name = "radioExample" Then

_IEFormElementRadioSelect ($oDoc,2, "radioExample", 1, "byIndex")
msgbox(0,"","Found it")
Endif
Next

_IEFormElementGetValue & _IEAction work great, just reference them to the $oElement, and search for an appropriate $element.Name, but I can't get the _IEFormElementRadioSelect to work.

The only difference between the _IEFormElementRadioSelect command from the example script found in the AutoIt helpfile is the reference to $oDoc. In the helpfile this is $oForm, which is found with a _IEFormGetObjByName, which I can't use (the site I'm automating doesn't return any forms).

Replace your _IEFormElementRadioSelect with _IEAction($element, "click")

Try this example; you can see the radio items being selected as the script runs:

#include <IE.au3>

$oIE = _IE_Example("form")
$oDoc = _IEDocGetObj($oIE)
$oArray = $oDoc.getElementsByTagName("input")
For $element In $oArray
    If $element.Name = "radioExample" Then
        _IEAction($element, "click")
        Sleep(2000)
    EndIf
Next
