6 posts in this topic

After I attach to an IE browser, how do I access the javascript variable in IE? Are they under document as objects?

Too terse. Try again.


Free Internet Tools: DebugBar, AutoIt IE Builder, HTTP UDF, MODIV2, IE Developer Toolbar, IEDocMon, Fiddler, HTML Validator, WGet, curl

MSDN docs: InternetExplorer Object, Document Object, Overviews and Tutorials, DHTML Objects, DHTML Events, WinHttpRequest, XmlHttpRequest, Cross-Frame Scripting, Office object model

Automate input type=file (Related)

Alternative to _IECreateEmbedded? better: _IECreatePseudoEmbedded  Better Better?

SciTe Debug mode - it's magic: #AutoIt3Wrapper_run_debug_mode=Y 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)

Thanks!!!

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)
