vick,

Welcome to the AutoIt forum.

But please pay attention to where you post - the "Examples" section where you started this thread is clearly marked: "Do not post general support questions here".  I have moved it for you, but would ask you to be more careful in future.

vick,

And when you post code please use Code tags - see here how to do it.  Then you get a scrolling box and syntax colouring as you can see above now I have added the tags.

got it sir

You have a check for your jquery object:

$jQuery = _InsertjQuery( $objAppIE )
If IsObj($jQuery) Then

But no Else clause to handle if it does not find object. Is it getting into the If statement? Where in the code, exactly, do you find it failing?

i have modified code like below

While Not ( IsObj($objScript.jQuery))
                Sleep (100)
                ;MsgBox(0,"","not found")
            WEnd

so here if I remove comment from msgbox and run script i got msgbox not found so i assume that my script is waiting here in loop.

I would thinks this should be checking against $objWindow.jQuery, not $objScript.jQuery. However, I couldn't get that to work either.

i tried  $objWindow.jQuery as well. but same result.

here a way to use jquery from AutoIt within a BrowserControl (not in IE)

https://www.autoitscript.com/forum/topic/185383-ie-11-automatic-using-jquery/?do=findComment&comment=1331640

 

[vick]

hi sir,

 

your example is working but hard to understand. can you try to look in my script what i am missing pls?

[Gianni]

Hi @vick,

for what I've tested in previous topics, the problem is that in recent versions of IE, the ability to refer to javascript objects is lost, while is still possible in the "Browser Control" instead. Take a look at these topics to see some evidence on this matter:

https://www.autoitscript.com/forum/topic/185387-value-of-js-variable-in-ie/

https://www.autoitscript.com/forum/topic/176731-autoit-javascript-roundtrip/

on post #13 of the first of previous topics @genius257 provided a way to bypass the proble, but it makes use of the "ExecScript" method that seems " is no longer supported" (read here: https://msdn.microsoft.com/en-us/library/ms536420(v=vs.85).aspx) even if at the moment seems that is still working.

Anyway, since I've still not found another way to reference javascript without the use of the "ExecScript" method, here is a script that allows you to use jQuery within an IE browser from within AutoIt using genius257's way.

You can modify also your script using the way used here to reference jQuery.

; This is not an optimal example; it demonstrates
; techniques that in my opinion you should not follow.

#include <ie.au3>

Global $oIE = _IECreate('http://www.google.com/') ; open a browser
Local $sScript_jQuery = BinaryToString(InetRead('http://code.jquery.com/jquery-1.9.1.js')) ; get jQuery listing into a variable

Local $oHead = _IETagNameGetCollection($oIE, "head", 0) ; reference the Head object

$objScript = $oIE.document.createElement('script') ; create a script element
$objScript.type = 'text/javascript'
$objScript.language = 'javascript'
$objScript.text = $sScript_jQuery ; fill the script element with the jQuery listing
$oHead.appendChild($objScript) ; insert the script into the page

; ...I suppose this allows to bring references from objects created in the "javascript global object" context, to the IE's context
; (from "javascript" context scope to "document" context scope)
$oIE.Document.parentWindow.execScript("document.body.jQuery = jQuery;")
$oIE.Document.parentWindow.execScript("document.body.eval = eval;")

$ojQuery = $oIE.Document.body.jQuery ; a reference to jQuery from within AutoIt
$oEval = $oIE.Document.body.eval ; a reference to eval from within AutoIt

While Not (IsObj($ojQuery))
    Sleep(100)
WEnd

MsgBox(0, "Debug", "jQuery is ready: IsObj($ojQuery) --> " & IsObj($ojQuery))

$ojQuery.noConflict() ; Relinquish jQuery's control of the $ variable

MsgBox(0, "", "Hit 'OK' and the Google's logo will Fade Out using jQuery")
; You can use the $oEval variable to run jQuery
$oEval("jQuery('#hplogo').fadeOut(3000);")
Sleep(4000) ; give enough time to the above jQuery effect to be performed

MsgBox(0, "", "Hit 'OK' now and the Google's logo will Fade In using jQuery again")
; You can also use the $ojQuery variable to run jQuery
$ojQuery('#hplogo').fadeIn(3000)
Sleep(4000) ; give time to jQuery to show the effect.

$oEval("alert('Bye Bye from javascript');")

_IEQuit($oIE)

yes it is working this way. can we use Xpath same way?

thanks
