IE Document Scrolling Problem

[StringingLong]

Having problems attempting to scroll the browser page in IE in some websites.

#include <IE.au3>

$oIe = _IECreate()
;$url1 = "https://signup.live.com/signup.aspx"   DOESNT SCROLL
;$url2 = "http://www.twitter.com"                        DOESNT SCROLL
;$url3  = "http://www.yahoo.com"                       SCROLLS
;$url4 = "http://www.facebook.com"                 SCROLLS
_IENavigate($oIe, $url)
$oIe.document.parentwindow.scroll(0, 200)

Any solutions to this?

I expect there is Javascript code on those pages that is actively working against you by scolling certain items into view in the background. I doubt that the .scoll method is not working.

Hi Dale thanks for reply.

Yes, I figured Javascript is getting in the way here. I wanted to run this by anyone here to ask if there is a workaround for this.

Looking at the JS source for the first url above, I see the exact line of JS causing this. It is housed in a function and gets called throughout many places.

The function situates around setting focus and calls scrollIntoView(true). I believe that is where it is forcing the issue.

I understand there is _IEHeadInsertEventScript to insert the overriding JS (btw, thanks for writing IE UDF). Looking at IE UDF source, this is appended (inserted after) into the head tag.

The args are:

$o_object = $oIe

$s_htmlFor = "document"

$s_event = ??? there is no event

$s_script = the overriding script

The third arg, $s_event though, seems to not let me be able to use this. The reason is because I am not trying to override a event, but rather a JS function.

It looks like I have to write my own _IEInsertJS to get around this?

Here is a function I use in my own code to accomplish this, along with two others I wrote at the same time:

Func IEEval($o_object, $s_eval)
    Return $o_object.document.parentWindow.eval($s_eval)
EndFunc ;==>IEEval

Func IEHeadInsertScript($o_object, $s_script)
    Local $o_head, $o_element
    $o_head = _IETagNameGetCollection($o_object, "head", 0)
    $o_element = $o_object.document.createElement('script')
    $o_element.type = 'text/javascript'
    $o_element.text = $s_script
    $o_head.appendChild($o_element)
    Return 1
EndFunc ;==>IEHeadInsertScript
 
Func IEHeadInsertStyle($o_object, $s_style)
    Local $o_head, $o_element
    $o_head = _IETagNameGetCollection($o_object, "head", 0)
    $o_element = $o_object.document.createElement('style')
    $o_element.type = 'text/css'
    $o_element.styleSheet.cssText = $s_style
    $o_head.appendChild($o_element)
    Return 1
EndFunc ;==>IEHeadInsertStyle

Dale, thanks for this. These three will come in very handy later.

I tried using IEHeadInsertScript() and overloading the function which I thought was causing the page to not scroll. I basicaly set it to do nothing and not pass the call onto the original JS function.

Unfortunately,it didnt trigger any execution at all.

I eventually came to a solution involving using _IEAction($formObj, "focus") along with Send tab keys and reverse tab keys to scroll. Not the most ideal solution as it involves knowing what form fields fit the height of the screen/page and of course it is screen height dependent. But for now it works.
