Automating some tasks on HTML page...

18 posts in this topic

Good evening everyone :)

Before all, I want to say that I'm doing this script to see how _IE* functions work, and see if my studs can hack a quiz I'm working on.

I want to clarify that I'm not automating any game, bypassing any CAPTCHAs, or anything that could damage anyone.

I was trying to autofill a form, based on which question is displayed.

The question is always stored in here:

<header>
    <h1><span class="questionid">1. </span>Here goes the question</h1>
</header>

And answers are stored in here:

<ul class="answers">
    <li><label><span><input id="answer_0" name="answer[]" type="radio" value="0">Answer 1</span></label></li>
    <li><label><span><input id="answer_1" name="answer[]" type="radio" value="1">Answer 2</span></label></li>
    <li><label><span><input id="answer_2" name="answer[]" type="radio" value="2">Anwser 3</span></label></li>
    <li><label><span><input id="answer_3" name="answer[]" type="radio" value="3">Answer 4</span></label></li>
</ul></fieldset></form></div>

And, there are 15 questions like this.

How can automatically fill my form?

Thanks in advance :)

Francesco

try the examples of IE.UDF or search the forum.

If you do not take mitigations in your server part on speed of answers I am sure people can hack your frontend thru the browser (provide a list of questions/answers and fill the forms quickly is a piece of cake).

If you make your site internet reachable we can try on your site

Good morning @junkew:)

Thanks for your reply.

I was looking at _IE* functions, but, I was unable to access to h1 text.

I tried with this, but I didn't manage to access to the innertext of h1:

Local $objIE_h1 = _IETagNameGetCollection($objIE, "h1")
If @error Then
    ConsoleWrite("Errore durante la lettura degli h1 nella pagina. - Errore: " & @error & @CRLF)
Else
    Local $strInnerText = _IEPropertyGet($objIE_h1, "innertext") ; ===========> It returns error 4.
    If @error Then
        ConsoleWrite("Errore durante la lettura della proprietà di h1. - Errore: " & @error)
    Else
        MsgBox($MB_ICONINFORMATION, "", $strInnerText)
    EndIf
EndIf

What am I doing wrong? :)

You get a collection back get property will only work on 1 element at a time. so $objIE_h1[0] or $objIE_h1[1]

case sensitive maybe? innerText?

alternatives:       textContent or innerHTML

 

see this example

I tried with this code below, but errors occurs:

Local $objIE_h1 = _IETagNameGetCollection($objIE, "h1") ; => It should return just one h1, because in the page there is only one h1.
    If @error Then
        ConsoleWrite("Errore durante la lettura degli h1 nella pagina. - Errore: " & @error & @CRLF) ; => No errors here
    Else
;~      For $objElement In $objIE ; => This displays nothing
;~          ConsoleWrite($objElement.textContent & @CRLF)
;~      Next
        Local $strInnerText = _IEPropertyGet($objIE_h1[0], "innerText") ; If I try with array element, this is the error that it returns:
        ; Expected a variable in user function call.:
        ; Local $strInnerText = _IEPropertyGet($objIE_h1[0], "innerText") ; Tried with innertext, innerText and textContent, but it's the same...
        ; Local $strInnerText = _IEPropertyGet(^ ERROR
        
        If @error Then
            ConsoleWrite("Errore durante la lettura della proprietà di h1. - Errore: " & @error)
        Else
            MsgBox($MB_ICONINFORMATION, "", $strInnerText)
        EndIf
    EndIf

try a loop around your example.

Check if you get 0,1 or n elements back

Local $oElements = _IETagNameAllGetCollection($objIE,"h1")
For $oElement In $oElements
    MsgBox($MB_SYSTEMMODAL, "Element Info", "Tagname: " & $oElement.tagname & @CRLF & "id: " & $oElement.id & @CRLF & "innerText: " & $oElement.innerText)
Next

I tried with this code right here, and nothing happened:

Local $objIE_h1 = _IETagNameGetCollection($objIE, "h1") ; => It's _IETagNameGetCollection(), and not _IETagNameAllGetCollection() as you prompted in the previous post!
    If @error Then
        ConsoleWrite("Errore durante la lettura degli h1 nella pagina. - Errore: " & @error & @CRLF)
    Else
        MsgBox($MB_ICONINFORMATION, "", @extended) ; => This MsgBox is to see how many h1 have been found ( It displays 1, as it is ).
        For $objElement In $objIE
            ConsoleWrite("Tagname: " & $objElement.tagname & @CRLF & "Id:" & $objElement.id & "Inner text:" & $objElement.innerText & @CRLF)
        Next

try the examples first to rule out nothing is wrong with your installation

Most likely there is no h1 (or maybe its case sensitive to be H1)

Whats your definition of "nothing happened" you either had output on console or a msgbox. If not the AutoIt broke on your first line of coding. 

I make the assumption you have the #include <IE.AU3> at top of your script.

The example gave me the expected result, so, I think we can exclude that there's nothing wrong with the installation of AutoIt;

There is only one h1 in the HTML, and it's not H1. By the way, the @extended after the _IETagNameCollection() confirms what I'm saying.

I tried with both ConsoleWrite() and MsgBox(), and in both cases I have had no output.

Absolutely yeah, or I should have had a bunch of errors in the script :)

Distraction errors have been always my Achille's heel!

Thank you so much! :)

Now I'll process this innerText with a Select...Case...EndSelect, and click on the correct answer...

Let's see :)

By the way, I'll post here if I'll need any information about _IE* functions :)

Thanks again for your support!

Have a wonderful day :)

Good morning everyone :)

@junkew

I managed to have textes of questions, but now, I have to click on the correct answer in order to continue with the quiz form.

This is what I tried:

For $i = 0 To 3 ; There are 3 answers, so I scan them in this For...Next loop
    $objAnswer = _IEGetObjById($objIE, "answer_" & $i) ; According to the id of the form, I get the object
    If @error Then
        ConsoleWrite("Errore durante la lettura della risposta #" & $i & " - Errore: " & @error & @CRLF)
    Else
        $strAnswer = $objAnswer.value ; =================> Here, I tried with innerText, textContent, innerHTML, but I always have a blank string
                                      ;                    It seems to be good with textContent, because the script was doing the clicks, but now
                                      ;                    seems broken...
        ConsoleWrite("Risposta: " & $strAnswer & @CRLF)
        If StringInStr($strAnswer, "ANSWER") Then ; Here it is the answer
            _IEAction($objAnswer, "focus")
            If @error Then
                ConsoleWrite("Errore durante il click sull'elemento. - Errore: " & @error)
                $blnGo = False ; I use this in a nested While, in order to have a flag which let continue ( if True ) the loop...
            Else
                Send("{ENTER}", $SEND_DEFAULT)
                $blnGo = True
                ExitLoop
            EndIf
        EndIf
    EndIf
Next

EDIT:

This is the HTML code, and I have to extract the text "ANSWER":

<li><label><span><input id="answer_0" name="answer[]" type="radio" value="0">ANSWER</span></label></li>

What can I do? :)

Thanks :)

No text is retrieved between <input> TEXT </input>...

Maybe I should look for the <span> instead of <input> ?

I really don't know! :)

My advice is to make it first in Excel with VBA

1. new module

2. add thru menu tools, references to

a. Microsoft Internet Controls

b. Microsoft HTML controls

3. new subroutine like this

#If VBA7 Then
    Declare PtrSafe Sub Sleep Lib "kernel32" (ByVal dwMilliseconds As LongPtr)
#Else
    Declare Sub Sleep Lib "kernel32" (ByVal dwMilliseconds As Long)
#End If

Sub testie()
    Dim oIE As New InternetExplorer                'A new IE object
    Dim oDocument As HTMLDocument                  'The main document that is opened/navigated to
    Dim oElements As IHTMLElementCollection        'Collection of elements
    Dim oElement As IHTMLElement                   'A specific element that can be queried
    Dim iTry As Long
    
    oIE.Visible = True  'Make me visible
    
    oIE.Navigate2 "www.google.nl"   'Navigate to my website
    'Wait till page is loaded or 50 * 200 is 10 seconds max
    Do While (oIE.Busy Or oIE.readyState <> 4) And (iTry < 50)
        iTry = iTry + 1
        DoEvents
        Sleep 200
    Loop

    If (oIE.Busy Or oIE.readyState <> 4) Then
        MsgBox "something wrong with loading page"
    End If
    
    Set oDocument = oIE.document
    Set oElements = oDocument.getElementsByTagName("input")
    
    Debug.Print "Found elements length:" & oElements.Length
    For Each oElement In oElements
        Debug.Print oElement.Name & oElement.className & oElement.innerHTML & oElement.Type & oElement.Title & oElement.outerHTML
    Next
    
End Sub

4. press F5 run

5. And when you debug/breakpoint in the forloop you can reveal all properties in the locals\quickwatch window

I managed to do what I was trying to do with this:

$objSpans = _IETagNameGetCollection($objIE, "span")
                    For $objElement In $objSpans
                        If $i >= 4 Then
                            $strAnswer = $objElement.innerText ; Testo della risposta
                            If StringInStr($strAnswer, "ANSWER") Then
                                $j = $i - 4
                                ConsoleWrite($j & ") Risposta: " & $strAnswer & @CRLF)
                                $objInput = _IEGetObjById($objIE, "answer_" & $j)
                                If @error Then
                                    ConsoleWrite("Errore durante la lettura della risposta #" & $i & " - Errore: " & @error & @CRLF)
                                Else
                                    _IEAction($objInput, "click")
                                    If @error Then
                                        ConsoleWrite("Errore durante il click sull'elemento. - Errore: " & @error)
                                        $blnGo = False
                                    Else
                                        Send("{ENTER}", $SEND_DEFAULT)
                                        $blnGo = True
                                        ExitLoop
                                    EndIf
                                EndIf
                            EndIf
                            $i+=1
                        Else
                            $i+=1
                        EndIf
                    Next
                    $i = 0
                    $j = 0

but now, I have to timing the questions' scan ( because the scan is done as soon the answer is let, so... ).

How could I add a sort of "when the answer is let, then wait for a different question, and proceed with all the code".

Or something similiar... :)

Thanks in advance :)

      Hi all,
       
      Anyone have any idea how to close all open tabs except a specific one I manually open.  Assuming I don't know what is open in all the tabs except just the one I want to keep open.
       
      I didn't want to use sendkeys and I was trying to use the following code to list the title (or url) of the 3 open tabs and  after I got that part working I would just close the other 2. This sample only displays the title of the first open tab
      #include <IE.au3> Const $ie_new_in_tab = 0x0800 $oIE = _IECreate("https://www.autoitscript.com") __IENavigate($oIE, "https://www.autoitscript.com/forum/", 1, $ie_new_in_tab) ;(obj,url,wait,param) __IENavigate($oIE, "https://www.google.com/", 1, $ie_new_in_tab) ;(obj,url,wait,param) Local $aIE[1] $aIE[0] = 0 Local $i = 1, $oIE While 1     $oIE = _IEAttach("", "instance", $i)     If @error = $_IEStatus_NoMatch Then ExitLoop     ConsoleWrite(_IEPropertyGet($oIE, "title") & @CRLF)     ReDim $aIE[$i + 1]     $aIE[$i] = $oIE ;each item holds object     $aIE[0] = $i ;first item holds count     $i += 1 WEnd MsgBox($MB_SYSTEMMODAL, "Browsers Found", "Number of browser instances in the array: " & $aIE[0]) ; This doesn't return the list of tabs in the console just the first tab  
      Thanks for any and all help

      Hey,
      i would like to set a value into an INPUT field.
      Checked the _IEFormElementSetValue function but that does require _IEFormGetObjByName and this is where the problem comes in. The input field I want to write to is not a part of a form tag. It is part of a table.
      <input type="text" class="w2" id="nabidka_vozidel_formular_tach_od" name="nabidka_vozidel_formular_tach_od" onchange="GLOBAL.pocetInzerceNZ(&quot;nabidka_vozidel_formular&quot;,&quot;tach_od&quot;,&quot;&quot;);" autocomplete="off"> I tried this but that didn't work:
      $oDownloadSamples = _IEGetObjById($oIE, "nabidka_vozidel_formular_tach_od") _IEFormElementSetValue($oDownloadSamples, "123") If you want to try the site I'm working with is https://www.tipcars.cz/. There is a menu on the top left hand side and if you click the "vyhledat" button the input fields will show up.
      Thanks
