Cannot navigate frame's innerHTML because it shows as empty.
Cannot navigate frame's innerHTML because it shows as empty.
- I'm trying to setup some IE automation. Currently I'm trying to access an anchor that is within a frame of the page. I cann access the frame element but, when I view its innerHTML it is empty and the hasChildNodes method returns false. Using the IE Developer toolbar add-on for IE I can see the DOM, the inner HTML of the frames and the anchor I want to navigate to but I'm unable to navigate via PS. Following is example of HTML I'm trying to traverse:
Here is my PS script:<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML Transitional//EN"><META http-equiv="Content-Type" content="text/html; charset=utf-8"> <HTML> <FRAMESET oncontextmenu="return false;" id="DESKTOPWRAPPERID" name="DESKTOPWRAPPERMAIN" frameSpacing="0" rows="46, *" frameBorder="0"> <FRAMESET oncontextmenu="return false;" id="DESKTOPMAINID" name="DESKTOPMAIN" frameSpacing="2" frameBorder="0" cols="220px, *"> <FRAME id="leftFrameId" title="Navigation Frame" onfocus="top.gFocus=false;" name="leftFrame" frameSpacing="2" src="/skle/HIMXXOServlet/ZdooMdJuMJqo-n2nxlqpNNg-aRt-toN_*/!STANDARD?Stream=NavigationPane&PrimaryPageName=Portal" frameBorder="0" scrolling="no" /> </FRAMESET> </FRAMESET> </HTML>
PS>$ie = new-object -com "InternetExplorer.Application" PS>$ie.navigate(<site url goes here>) PS>$ie.visible = $true ...wait for page to load... PS>$ie.document.getElementById("leftFrameId").name PS>leftFrame ...So I'm able to access the frame element... PS>$ie.document.getElementById("leftFrameId").innerhtml PS> ...Nothing is returned for innerHTML property... PS>$ie.document.getElementById("leftFrameId").hasChildNodes() PS>false ...No child nodes, however, viewing DOM via IE Developr Toolbar Add-on shows child nodes...Any suggestions would be appreciated. Thanks.

- Hi,
It’s more of a Web development issue, it’s suggested to submit a new post in the MSDN forum to get more suggestions. They are the best resource for this kind of problem.

- Maybe you have to check your IE security settings.

http://blogs.msdn.com/powershell/archive/2006/09/10/748883.aspx - Thanks for they reply. Helpful suggestions but they did not resolve the problem. I did some more research and found a proposed solution that states that I must navigate to the url of the frame in order to traverse it. I did this using the IHTMLDocument4::createDocumentFromUrl method and I was able to traverse the frame's dom, however, when I try to invoke the click method on my anchor control nothing happens. Is that the best method to use or is there a better way to navigate the frame's url(src)?
- I'll admit to not completely following what you're doing...
Now you mention trying to invoke a click method... Is that a click method or click event? Events aren't supported in PowerShell v1. Out-of-the-box at least... If you're using v1, I don't know how you'd (assuming it is possible) leverage: http://www.codeplex.com/pseventing . The click method; not the event. As an example, I'm trying to do the following:
PS>$btn = $ie.document.getElementById("elementid")
PS>$btn.click()
The problem is that the html control with the ID 'elementid' (an anchor tag in my situation) is in a series of nested frames. I can access the frame where the anchor control resides but, the frame shows as having no child nodes. It has been suggested that I need to navigate to the frame's src url in order to traverse its child nodes. The only way I've been able to do this is to use IHTMLDocument4::createDocumentFromUrl method. I call this method and save the result, which should be the frame's DOM, to a PS variable. I then call getElementById() and locate my anchor tag and save a reference to it in another PS variable, say $anchor. I then try to call $anchor.click() and nothing happens. That is my dilemma.- Hi,
I create a 2.html file:
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML Transitional//EN"><META http-equiv="Content-Type" content="text/html; charset=utf-8">
<HTML>
<FRAMESET oncontextmenu="return false;" id="DESKTOPWRAPPERID" name="DESKTOPWRAPPERMAIN" frameSpacing="0" rows="460, *" frameBorder="0">
<FRAMESET oncontextmenu="return false;" id="DESKTOPMAINID" name="DESKTOPMAIN" frameSpacing="2" frameBorder="0" cols="2200px, *">
<FRAME id="leftFrameId" title="Navigation Frame" onfocus="top.gFocus=false;" name="leftFrame" frameSpacing="2" src="1.html" frameBorder="0" scrolling="no">
</FRAME>
</FRAMESET>
</FRAMESET>
</HTML>
And then run the following commands:
$ie = New-Object -comObject InternetExplorer.Application
$ie.visible = $true
$ie.navigate('e:\2.html')
$ie.Document.body.innerHTML
Got the following result:
<FRAMESET id=DESKTOPMAINID oncontextmenu="return false;" frameSpacing=2 name=DESKTOPMAIN cols="2200px, *" frameBorder=0><FRAME i
d=leftFrameId onfocus=top.gFocus=false; title="Navigation Frame" frameSpacing=2 src="1.html" frameBorder=0 name=leftFrame scroll
ing=no></FRAMESET>
Please try the same files on your side.
Thanks.

However, my problem is when I try to navigate the html nodes directly under the frame with id=leftFrameId. I did not post any HTML under this frame in my example above and I apologize for any confusion. There is HTML that exists under this frame but I am unable to view or navigate it.
And after writing the paragraph above I went and did what I should have done from the very beginning...I viewed the source of the page. What I found is that the frame's content is dynamically constructed via javascript. I feel like a heel not doing this before.
Does anyone know how to go about automating a control's click event when the control is dynamically constructed (i.e. not sent as straightforward HTML from server to client)? Should i open this question in a new post? - Hi,
