How to get variable value with 'document.parentwindow.execScript'?

[Letraindusoir]

#include <IE.au3>
#include <Array.au3>

Local $oIE = _IECreate()
Local $ss = ""
$ss &= 'var fruits = new Array();'
$ss &= 'fruits[0] = "pear";'
$ss &= 'fruits[1] = "peach";'
$ss &= 'fruits[2] = "pineapple";'
$ss &= 'fruits[3] = "strawberry";'
$ss &= 'return fruits;'

;Local $aa = $oIE.document.parentwindow.execScript($ss)
Local $aa = $oIE.document.parentwindow.eval($ss)

If IsArray($aa) Then
    _ArrayDisplay($aa, '$aa')
EndIf

_IEQuit($oIE)

error occurred:

Local $aa = $oIE.document.parentwindow.eval($ss)
Local $aa = $oIE.document.parentwindow^ ERROR

As above

if want to get the value of the variable 'fruits' in the statement

How does it work?

thanks!

Eval is not working anymore with ObjCreate("InternetExplorer.Application").  Here's another way :

#include <Constants.au3>
#include <IE.au3>
#include <Array.au3>

Example2()

Func Example2 ()
  Local $hGUI = GUICreate("Browser", @DesktopWidth / 2, @DesktopHeight / 2)
  ;GUISetState() ;Show GUI

  Global $oIE = ObjCreate("Shell.Explorer.2")
  $hIE = GUICtrlCreateObj($oIE, 0, 0, @DesktopWidth / 2, @DesktopHeight / 2)
  $oIE.navigate('about:blank')
  $arr = StringSplit($oIE.Document.parentWindow.eval('function tt() {var fruits = [];fruits[0] = "pear";fruits[1] = "peach";' & _
    'fruits[2] = "pineapple";fruits[3] = "strawberry"; return fruits[0]+"|"+fruits[1]+"|"+fruits[2]+"|"+fruits[3];}; tt();'), "|", $STR_NOCOUNT)
  _ArrayDisplay($arr)
EndFunc

Thanks!

But Still Report Error:

$arr = StringSplit($oIE.Document.parentWindow^ ERROR

Windows 7 + IE11

Is it related to the system and browser?

There's no reporting error with 'Document.parentWindow.execScript'

It is working for me on Win7.  You may need to set FEATURE_BROWSER_EMULATION in the registry for AutoIt3.exe to "0x2AF9". 

HKEY_CURRENT_USER\Software\Microsoft\Internet Explorer\Main\FeatureControl\FEATURE_BROWSER_EMULATION

[Letraindusoir]

#include <Constants.au3>
#include <IE.au3>
#include <Array.au3>

Example2()

Func Example2 ()
  Local $hGUI = GUICreate("Browser", @DesktopWidth / 2, @DesktopHeight / 2)
  ;GUISetState() ;Show GUI

  Global $oIE = ObjCreate("Shell.Explorer.2")
  $hIE = GUICtrlCreateObj($oIE, 0, 0, @DesktopWidth / 2, @DesktopHeight / 2)
  $oIE.navigate('about:blank')
  $arr = $oIE.Document.parentWindow.eval('alert(123)')
EndFunc

After simplified

tests are still 'execScript no-error-reporting' and 'eval error-reporting'

[Nine]

IDK.  Since it works for me.  Try different value of emulation ?

; IE11 edge mode: 11001 (0x2AF9)
; IE11: 11000 (0x2AF8)
; IE10: 10001 (0x2711)
; IE10: 10000 (0x02710)
; IE 9: 9999 (0x270F)
; IE 9: 9000 (0x2328)
; IE 8: 8888 (0x22B8)
; IE 8: 8000 (0x1F40)
; IE 7: 7000 (0x1B58)

I think There is something wrong with the grammar of javascript sentences

I have used 'eval' or 'execScript' before, that sometimes work  sometimes don't work

[Letraindusoir]

After Set FEATURE_BROWSER_EMULATION in the registry for AutoIt3.exe to "0x2AF9",It's Working Fine

It's amazing

Thanks Nine !

You are welcome

var fruits = new Array();
fruits[0] = "pear";
fruits[1] = "peach";
fruits[2] = "pineapple";
fruits[3] = "strawberry";
console.log(fruits)

The above statement runs on the browser console without error
Not with eval or execScript.
It seems that this is also a puzzling problem

[Nine]

it works also for me using var fruits = new Array();  You may have a glitch in your code.
