Doesn't work needs to be ripped out of the troubleshooting lexicon. It means that what you tried did not produce the results you expected. It begs the questions 1) what did you try?, 2) what did you expect? and 3) what happened instead?

From autoit, I can attach to an IE browser, IE browser is running a html page with javascript, How can I get javascript variable's value in the browser?

For example, I get the input field's value by doing:

$oForm = _IEFormGetObjByName ($oIE, "form1")

$oQuery = _IEFormElementGetObjByName ($oForm, "f")

MsgBox(0, "Document Created Date", $oQuery.value)

How can I retrieve the a javascript variable's value? Are javascript variable an object under the document?

Too terse. Try again.

That would be 'eval' if I understand you properly...

For example:

#include <IE.au3>

$oIE = _IECreate()
_IEDocWriteHTML($oIE, "<html><head><script luanguage = 'javascript'>foo='bar';</script></head><body></body></html>")

ConsoleWrite("foo = " & $oIE.document.parentwindow.eval('foo') & @CR)

One more question: Should "IsDeclared" work for checking the existance of a javascript variable?

For example:

if not $oIE.document.parentWindow IsDeclared("j") Then

;;; The variable "j" is not declared

EndIf

That would be 'eval' if I understand you properly...

For example:

#include <IE.au3>

$oIE = _IECreate()
_IEDocWriteHTML($oIE, "<html><head><script luanguage = 'javascript'>foo='bar';</script></head><body></body></html>")

ConsoleWrite("foo = " & $oIE.document.parentwindow.eval('foo') & @CR)
