FF.au3 (V0.6.0.1b-10)

[13lack13lade]

@mootius:

The function _FF_Call is for executing JavaScripts:

FFEx.au3

@13lack13lade:

You can interact with them e.g. with _FFXpath and _FFClick.

Look please on the examples: _FFClick and _FFXpath

The XPath can you copy from FireBug.

 

Hey, got firebug, not sure how to interact with the buttons since they all have the same class name, no id, no tags, nothing this is what it says when i view source code of the object im trying to click on

<div class="html-face">Location</div>

using firebug to copy xpath i get :

/html/body/div/div/div[2]/div/div[4]/div/div[2]/div/div[2]/div/div/div/div[3]/div/div[2]/div/div[3]/div/div[2]/div/div[5]/table/tbody/tr/td/table/tbody/tr/td[3]/div/div/div/div/div

how do i use any of this to click on the button?

For give me I'm new to the ff.au3 library but how would i go about getting a list of id's class's or name's from a specific element then retrieve the inner text from each element returned.

like this

<div id="conainer">

<div id="box1">
some text
</div>

<div id="box2">
some text
</div>

<div id="box3">
some text
</div>

</div>

[SupaNewb]

Here is a half a$$ script I wrote to check ff and mozrepl status (it is only reliable if firefox.exe is installed in default location).

I just use "get status" button. Hope it is helpful to you.

[Rickname]

Same problem as

Arclite86

 

I did EVERYTHING PERFECT :

Started MozRep, set it as auto start, put FF.au3 and FFEx.au3 in the Includes directory and included thme in my project, and then tested a little example script from the example menu of this UDF and same ERRORS as Arclite86 ((
 

[Rickname]

Ok I managed the above, I don't know how but somehow, BUT I have ANOTHER BIG problem ! :

I included the FF UDF but it still gives me "undefined function" error !
 

The funny part is, that actually it includes the file because if I put a Msgbox() function in the UDF , it runs the function so it reads the UDF but it does'nt recognises the declared functions from it globally

Can you explain this ??

Post your script that isn't working, otherwise we'd be guessing what you did wrong.

I am guessing this is the 'undefined Function error'. I had no issues until upgrading Autoit version 3.3.8.1 to version 3.3.10.2.

Strange though, if I paste the entire UDF (FF.au3) in any of my scripts then it works like a charm(without turning off Au3check).

This is your issue. Try opening and saving the file with a different encoding method.

I dont know exactly how to solve this, should I create a new map in the "HKEY_LOCAL_MAHCINESOFTWAREWow6432NodeMozilla Firefox" named *CurrentVersion* like its been shown in the error and than create  a Main map?  How can i solve this so autoit can locate firefox?

[Danp2]

Somewhere along the way, a backslash has been accidentally removed from the ff.au3 code. To solve the issue, change this line:

Local $sFFExe = RegRead($sHKLM & "" & RegRead($sHKLM, "CurrentVersion") & "\Main", "PathToExe")

to:

Local $sFFExe = RegRead($sHKLM & "\" & RegRead($sHKLM, "CurrentVersion") & "\Main", "PathToExe")

thank you so much, it worked.. finally

[tommytx]

wow! that was exactly what was wrong with mine alos... Thanks

[Arclite86]

Firefox doesn't work hidden

I have tried this

_FFStart("https://website.com", False, Default, False, True)

and this

_FFStart("https://website.com", Default, Default, True)

But it is not working , PLease Help!

[Danp2]

As mentioned in the other thread, you need to update the UDF by changing the two instances of "[CLASS:MozillaUIWindowClass]" to "[CLASS:MozillaWindowClass]".

Hello everyone,

Thanks

Please correct me if I am wrong, but this part of the code of _FFTableWriteToArray just doesn't make sense, since tables are not constructed this way. To solve this the second half should be deleted, because it doesn't swith the row and makes each row consist of the same information from the first row.

$aRows = _FFXPath($sTable & "//tr//td[" & $i + 1 & "]", $sReturnMode, 6, $iFilter)

Else
        $iCols = _FFXPath($sTable & "//tr[last()]//td", Default, 10)
        Local $aTable[$iRows][$iCols]

        If $iCols > $iRows Then
            For $i = 0 To $iRows - 1
                $aCols = _FFXPath($sTable & "//tr[" & $i + 1 & "]//td", $sReturnMode, 6, $iFilter)
                If $aCols[0] > 0 Then
                    For $j = 0 To $iCols - 1
                        $aTable[$i][$j] = $aCols[$j + 1]
                    Next
                EndIf

                    For $j = 0 To $iRows - 1

Excellent, thank you for this script.

Translated some comments and variable names to English:

 

I apologize if responding to a 5 year old post with an update is considered poor form but I frequently refer to this thread when looking for further information on FF.au3 and suspect I'm not the only one and decided to post the code below for posterity. I've made a few small updates to the MozRepl_Detect() function originally created by Stilgar (Thorsten Willert) and updated by Manadar. I needed to deploy a script that uses mozrepl to several workstations and found the original script useful, but badly in need of an update to accomodate 64-bit OS's and the latest versions of Firefox. I wasn't very thorough and didn't add much in the way of error-checking, but it got the job done. Please feel free to edit/correct as you see fit .

    AutoIt Version: v3.3.12.0
    Author: Thunder-man (Frank Michalski)

    Script Function:  _MozRepl_Detect()
    Description:      Checks a Firefox profile for the MozRepl extension and installes it if not available.
    default:          $sProfile = "default"
    Return values:    True or False
    V 1.0 ==> 15.09.2007
    V 1.1 ==> 02.08.2008, updated by Stilgar (Thorsten Willert)
    changed the path-macro to @AppDataDir
    changed the ""-profil to "default"
    V1.2 ==> 03.03.2009, updated by Stilgar (Thorsten Willert)
    changed MozLab to MozRepl
    V2.0 ==> 17.03.2009, added intall-option for MozRepl by Stilgar (Thorsten Willert)
    V3.0 ==> 6/11/2014 by Gonnosuke.  Changes are below:
        *  Updated the download path for mozrepl
        *  Added support for Wow6432Node reg entry when 32bit FF is installed on 64-bit OS  
         (Note: Win7/8.x have an AppPaths reg key that make the process of reading path info easier. 
          I haven't used it here for the sake of consistency but if interested the key is below: 
          HKLM\SOFTWARE\Wow6432Node\Microsoft\Windows\CurrentVersion\App Paths 
        *  Updated the routine that reads FF path and version information from the registry. 
        *  The profiles.ini file has a (new?) key called IsRelative. The default is 1 and if true then the Path
         includes a forward slash instead of a backslash. If IsRelative=1 then I use StringReplace as a quick fix
        *  Extension info is now saved with .xpi file extension e.g. "\extensions\mozrepl@hyperstruct.net.xpi  
        *  Tested with FF versions 29.x  but will likely work with other recent versions of FF.

Edit: I forgot to mention that if you want to configure MozRepl to start automatically without user intervention just append the following line to the user.js file in the FF profile directory:  user_pref("extensions.mozrepl.autoStart", true);  If the user.js file doesn't exist, simply create it, and mozrepl will be enabled when FF is restarted. The user.js takes precedence over the prefs.js file so please be aware that once you make this change, anyone using that profile will not be able to undo the setting via about:config.
