Retrieving Elements Within a Frame

ilhom · 06 Sep 2019, 11:33

In the javascript below in an Internet Explorer page I'm trying to obtain the value of iw_board_deviceName.

<html>
 <head>...</head>
 <frameset rows="57,1*">
  <frame name="toplogo" src="top.asp" frameborder="0" noresize="" scrolling="NO">...</frame>
  <frameset cols="230,*">
   <frame name="contents" src="contents.asp" frameborder="0">...</frame>
   <frame name="main" src="setup_option.asp" frameborder="0" marginwidth="0" marginheight="0" scrolling="auto">
    <html>
     <head>...</head>
     <body onload="iw.ChangeOnLoad();">
      <h2>System Information</h2>
      <form name="sysinfo" onsubmit="return CheckValue(this)" action="/forms/iw_webSetParameters" method="POST">
       <table width="100%">
        <tbody>
         <tr>
          <td width="30%" class="column_title">Device name</td>
          <td width="70%">
           <input name="iw_board_deviceName" type="text" size="40" maxlength="31" value="Device MAC Address" />

I've referred to several pages online to retrieve this value, however I have been unsuccessful. Here are a few I've been referencing.
https stackoverflow.com/questions/11563638/how-do-i-get-the-value-of-text-input-field-using-javascript Broken Link for safety
https codippa.com/how-to-select-an-element-inside-a-frame-using-javascript/ Broken Link for safety

Code: Select all

;Create ie Window
wb := ComObjCreate("InternetExplorer.Application")

;Make ie Window Visible
wb.Visible := 1

;Navigate to Moxa page
wb.Navigate("http 192.168.127.253  ")  Broken Link for safety

;Wait while page loads
While wb.readyState != 4 || wb.document.readyState != "complete" || wb.busy
	Sleep, 20

;Retrieve MAC address - TESTING
MAC := wb.window.frame["main"].document.getElementsByName("iw_board_deviceName")
;MAC := wb.window.frames["main"].document.getElementID("iw_board_deviceName")
;MAC := wb.document.getElementById("myframe1").contentWindow.document.getElementByID("iw_board_deviceName")

;Display Info from the page
MsgBox %MAC%

Can anyone help figure out what I'm doing wrong? The msgbox currently displays no information, so I'm obviously failing to retrieve the info I'm looking for.

Edit: The wb.Navigate line of code I have works. For some reason it keeps stripping the :// between the IP address and http on this forum.

In this part wb.window.frame["main"], it says frame without a final s.

Is that a typo just here in your post? or is it also a typo in your code?

I tried with both the s and without the s just to test. No luck with either one.

You should use frames.
Also, getElementsByName returns a collection, so you need to get its first element with square brakets and then its value
For example getElementsByName('name')[0].value

MAC := wb.window.frames["main"].document.getElementsByName("iw_board_deviceName")[0].value

I get an error on this line stating it's an unknown name.

Getfree · 06 Sep 2019, 15:23

What happens if instead of wb.window.frames you write wb.document.frames ?

ilhom · 06 Sep 2019, 15:37

I received an unspecified error doing that.

I searched through the source code of the site and that is the only instance of iw_board_deviceName so I don't see how that name would be getting confused.

What kind of control is wb? Is it a Shell.Explorer ActiveX control? How are you creating it?

Edited original post. Can't believe I forgot to include the variable creation.

wb := ComObjCreate("InternetExplorer.Application")

Getfree · 06 Sep 2019, 15:59

Do any of these give you the number 3?
MsgBox % wb.document.frames.length
MsgBox % wb.document.parentWindow.frames.length
MsgBox % wb.window.frames.length

ilhom · 06 Sep 2019, 16:05

Message box displayed 3:
MsgBox % wb.document.frames.length
MsgBox % wb.document.parentWindow.frames.length

Unknown name error, and displayed nothing in the message box:
MsgBox % wb.window.frames.length

Getfree · 06 Sep 2019, 16:12

You are all set, then.
MAC := wb.document.frames["main"].document.getElementsByName("iw_board_deviceName")[0].value

ilhom · 06 Sep 2019, 16:35

That line of code provides me this error

Error: 0x80020101 -
Specifically: Frames

Try your script on a local HTML file, like this one:

Code: Select all

<html>

<frameset rows="57,1*">
	<frame name="toplogo" src="about:blank"></frame>
	<frameset cols="230,*">
		<frame name="contents" src="about:blank"></frame>
		<frame name="main" src="frame.html">
	</frameset>
</frameset>

</html>

Create a frame.html file as well.

This is to rule out that the problem isn't some sort of permissions or access violations related to cross-frame scripting.

try adding parentWindow

Code: Select all

wb.document.parentWindow.frames["main"].document.getElementsByName("iw_board_deviceName")[0].value

I tried navigating to this html file and I still receive the same error:

Bumping.

Still struggling on this and I feel a bit stumped. I've searched online for a while now and everything I've found is consistent with what was suggested here. Perhaps it has something to do with the fact the frame is within 2 framesets?

Code: Select all

Pwb:= ComObjCreate( "InternetExplorer.Application" )
Pwb.Navigate("https://www.w3schools.com/tags/tryit.asp?filename=tryhtml_frame_cols")
Pwb.Visible:= True
While ( Pwb.Busy || Pwb.ReadyState != 4 )
   Sleep 10	
msgbox page loaded

oIE := IEGet()
msgbox % oIE.document.documentElement.OuterHtml

iFrame := ComObject( 9, ComObjQuery(oIE.document.parentWindow.frames["iframeResult"],"{332C4427-26CB-11D0-B483-00C04FD90119}","{332C4427-26CB-11D0-B483-00C04FD90119}"), 1)
msgbox % iFrame[0].document.documentElement.OuterHtml



IEGet(name="") {
   IfEqual, Name,, WinGetTitle, Name, ahk_class IEFrame     ;// Get active window if no parameter
   Name := (Name="New Tab - Windows Internet Explorer")? "about:Tabs":RegExReplace(Name, " - (Windows|Microsoft)? ?Internet Explorer$")
   for wb in ComObjCreate("Shell.Application").Windows()
      if wb.LocationName=Name and InStr(wb.FullName, "iexplore.exe")
         return wb
}

      if wb.LocationName=Name and InStr(wb.FullName, "iexplore.exe")
         return wb
}

I adjusted the msgbox % oIE.document.documentElement.OuterHtml to FileAppend, % oIE.document.documentElement.OuterHtml, GuiFrameTest.txt so that I could inspect the output easier. I'm not that familiar with JavaScript, so I can't tell what exactly I'm looking for. Could an explanation be provided for the IEGet() function, and what exactly iFrame is looking for?

You can search for commands that are used in that function and read manual what they do.
