Hi,

I have a web page that seems to dynamically create all the buttons the same way. As result, they all have same classes and names. If I try to click them, nothing happens.

I am currently testing with following script:

Local $oBtns = _IETagNameGetCollection($oIE, "button")


For $oBtn In $oBtns

    If String($oBtn.classname) == "this is the popular button name" Then

        $oFound = $oBtn

        If IsObj($oFound) Then

            _IEAction($oBtn, "click")

            ConsoleWrite($oBtn.classname & @CRLF)

        EndIf

    EndIf

Next

Classname is populated correctly. Unfortunately, the _IEAction click does not apply on any of the them.

DOM Explorer sees the buttons following way:

<button class="this is the popular button name"></button>

No name, no id, no label.

Is there any way to click these buttons?

Is there any way to differentiate the buttons from each other?

Thanks

Just because the page is private doesn't mean you can't make a reproducer.

Does this match the sort of page you are working with?

#include <FileConstants.au3>
#include <IE.au3>

Local $sFileName = "reproducer.html"
Local $sPath = @SCriptDir & "/" & $sFileName
Local $sURL = "file:///" & $sPath


IF Not FileExists($sPath) Then
    ; write file
    Local $hFile = FileOpen($sPath, $FO_OVERWRITE)
    FileWrite($hFile, "<html><head><title>Identical Buttons</title></head><body><button class=""btnclass""></button><button class=""btnclass""></button></body></html>")
    FileClose($hFile)
EndIf


Local $oIE = _IECreate($sURL)
Local $oDoc = _IEDocGetObj($oIE)

If Not IsObj($oDoc) Then
    $oIE = _IEAttach($sFileName, "url")
    $oDoc = _IEDocGetObj($oIE)
EndIf


Local $oBtns = _IETagNameGetCollection($oDoc, "button")
For $oBtn In $oBtns
    If String($oBtn.classname) == "btnclass" Then
        $oFound = $oBtn

        If IsObj($oFound) Then
            _IEAction($oBtn, "click")
            ConsoleWrite($oBtn.classname & " " & @error & @CRLF)
        EndIf
    EndIf
Next

_IEQuit($oIE)

_IEQuit($oIE)

That was it exactly.

While wondering why I did not get your IE object to work, I updated AutoIT and that fixed the original problem....

Sorry about the hassle everyone and thank you for your help! :) I feel embarrassed now..

Most of the time, if there are the same class/id/name string names, the tag has a unique parent id/name/class/etc.

eg.

<div id=uniqueName><input class="nonuniqueName" type="button"></div>

You could get the object of the uniqueName, then its child and you have the unique button for that tag without bleeding into all the other ones.

This is necessary for CSS rendering/positioning/etc.

In this >library there are some class functions.  Like how you use the _IEGetObjByName() function, you could use the _IEJS_JSGetObjByClassName() and use the "Index" parameter if you know which index the button falls into in the html.

Edit:

Evidently Mat hit what you needed, I'm unsure what it was that did it atm though lol.

Hi,

I used the reproducer in combination with the IEJS.

Added:

#include <IEJS.au3>

$testing = _IEJS_JSGetObjByClassName($oDoc, "btnclass", "button", 1)

#include <FileConstants.au3>
;#include <IE.au3>
#include <IEJS.au3>

Local $sFileName = "reproducer.html"
Local $sPath = @SCriptDir & "/" & $sFileName
Local $sURL = "file:///" & $sPath


IF Not FileExists($sPath) Then
    ; write file
    Local $hFile = FileOpen($sPath, $FO_OVERWRITE)
    FileWrite($hFile, "<html><head><title>Identical Buttons</title></head><body><button class=""btnclass""></button><button class=""btnclass""></button></body></html>")
    FileClose($hFile)
EndIf


Local $oIE = _IECreate($sURL)
Local $oDoc = _IEDocGetObj($oIE)

If Not IsObj($oDoc) Then
    $oIE = _IEAttach($sFileName, "url")
    $oDoc = _IEDocGetObj($oIE)
EndIf

Local $oBtns = _IETagNameGetCollection($oDoc, "button")
For $oBtn In $oBtns
    If String($oBtn.classname) == "btnclass" Then
        $oFound = $oBtn

        If IsObj($oFound) Then
            _IEAction($oBtn, "click")
            ConsoleWrite($oBtn.classname & " " & @error & @CRLF)
        EndIf
    EndIf
Next

$testing = _IEJS_JSGetObjByClassName($oDoc, "btnclass", "button", 1)

_IEQuit($oIE)

This results to:

btnclass 0
btnclass 0
!>19:42:55 AutoIt3.exe ended.rc:-1073741571
+>19:42:55 AutoIt3Wrapper Finished.
>Exit code: 3221225725    Time: 7.474

The failing line is of course the only one I added. Did I understand something wrong about the function syntax (IEObject, class name, class, occurense)?

I'd agree with SmOke_N

If there is infact some unique parent, you can use my signature to grab the child, like this (an example of finding the input with SmOke_N's strucutre.

$xpath = "//div[@id='uniqueName']/input[@class='nonuniqueName']"
IEbyXPATH-Grab IE DOM objects by XPATH IEscriptRecord-Makings of an IE script recorder ExcelFromXML-Create Excel docs without excel installed GetAllWindowControls-Output all control data on a given window.

Unless you mean the fact that you didn't use the _iejs_jsgetobjbyclassname() function really at all... i guess not?

#include <FileConstants.au3>
;#include <IE.au3>
#include <IEJS.au3>

Local $sFileName = "reproducer.html"
Local $sPath = @SCriptDir & "/" & $sFileName
Local $sURL = "file:///" & $sPath


IF Not FileExists($sPath) Then
    ; write file
    Local $hFile = FileOpen($sPath, $FO_OVERWRITE)
    FileWrite($hFile, "<html><head><title>Identical Buttons</title></head><body><button class=""btnclass""></button><button class=""btnclass""></button></body></html>")
    FileClose($hFile)
EndIf


Local $oIE = _IECreate($sURL)
Local $oDoc = _IEDocGetObj($oIE)

If Not IsObj($oDoc) Then
    $oIE = _IEAttach($sFileName, "url")
    $oDoc = _IEDocGetObj($oIE)
EndIf

Local $oBtn = _IEJS_JSGetObjByClassName($oDoc, "btnclass", "button", 1)
If Not IsObj($oBtn) Then
    ConsoleWrite("oops" & @CRLF)
    Exit 1
EndIf

ConsoleWrite("What are you waiting for?" & @CRLF)
_IEQuit($oIE)

BTW, what version of IE are you using?

I kept getting the activex popup with the code above, after debugging that, I noticed I left a debug string in the javascript for that function... so I'll be updating my code shortly with a fix for that and one other thing on the major version function.

Re-installed AutoIT now with x64 binaries to test if I would get better results.

"C:\Program Files (x86)\AutoIt3\Include\IEJS.au3" (615) : ==> Recursion level has been exceeded - AutoIt will quit to prevent stack overflow.:
Func _IEJS_GetObjType(ByRef $oObj)

->19:08:14 AutoIt3.exe ended.rc:1
+>19:08:14 AutoIt3Wrapper Finished.
>Exit code: 1    Time: 2.984

It failed on the same line but probably gives more information about the root cause than the previous one did.

I have a comment on the _IEJS_CallObjExecScript() down by the Eval call.  If both failed, it is the only place where a recursion would happen.

Why would they both fail?  Your browser is not allowing javascript injection or the browsers javascript interpreter is broken.

Why?:

1.  You haven't enabled javascript.

2.  There was an update on Dec 18 (if you check the IE11 posts around the internet and on this forum), you need to uninstall that.
