measure lenth of a webpage?

[neo007]

Hi all,

I'm working on a script about a website. This website has many pages that are named by numbers. All pages are the same length. My script will navigate pages one by one and read the text of each.

The problem is, some pages show 0 text, you have to refresh several times to fix it. In this case, there's no slider at right hand.----Normally the slider is the same length for these pages( = pagedown twice).

So, I want to check every page's slider length and then decide whether to refresh.

I checked the help file, found nothing.

I noticed that there's a :

#Include <GuiSlider.au3>

_GUICtrlSlider_GetThumbLength($hWnd)

But I used Au3info.exe, can not find any slider object in an IE window, so can not get "$hWnd".

Any idea, please?

Thanks.

Perhaps _IEPropertyGet and get the height of the BODY object.

Perhaps _IEPropertyGet and get the height of the BODY object.

Thanks Dale, but "BODY" is not in the property list of _IEPropertyGet

Look at this example:

$oIE = _IE_Example("form")

$oForm = _IEFormGetObjByName($oIE, "ExampleForm")
$oTextArea = _IEFormElementGetObjByName($oForm, "textareaExample")

; Get coordinates and dimensions of the textarea
$iScreenX = _IEPropertyGet($oTextArea, "screenx")
$iScreenY = _IEPropertyGet($oTextArea, "screeny")
$iBrowserX = _IEPropertyGet($oTextArea, "browserx")
$iBrowserY = _IEPropertyGet($oTextArea, "browserY")
$iWidth = _IEPropertyGet($oTextArea, "width")
$iHeight = _IEPropertyGet($oTextArea, "height")

; Outline the textarea with the mouse, come to rest in the center
MouseMove($iScreenX, $iScreenY)
MouseMove($iScreenX + $iWidth, $iScreenY)
MouseMove($iScreenX + $iWidth, $iScreenY + $iHeight)
MouseMove($iScreenX, $iScreenY + $iHeight)
MouseMove($iScreenX, $iScreenY)
MouseMove($iScreenX + $iWidth/2, $iScreenY + $iHeight/2)

#include <IE.au3>

$oIE = _IE_Example("form")
$oBody = _IETagNameGetCollection($oIE, "BODY", 0)
ConsoleWrite($oBody.scrollHeight & @CR)

And you'll see that the _IEPropertyGet value returns the same answer as big_daddy's solution:

#include <IE.au3>

$oIE = _IEAttach("autoit")
$oBody = _IETagNameGetCollection($oIE, "BODY", 0)
ConsoleWrite("scrollHeight: " & $oBody.scrollHeight & @CR)
ConsoleWrite("Body Height: " & _IEPropertyGet($oBody, "height") & @CR)

Are you sure?

#include <IE.au3>

$oIE = _IE_Example("form")
$hWnd = _IEPropertyGet($oIE, "hwnd")
$oBody = _IETagNameGetCollection($oIE, "BODY", 0)

ConsoleWrite("scrollHeight: " & $oBody.scrollHeight & @CR)
ConsoleWrite("Body Height: " & _IEPropertyGet($oBody, "height") & @CR)

WinSetState($hWnd, "", @SW_MAXIMIZE)

ConsoleWrite("scrollHeight: " & $oBody.scrollHeight & @CR)
ConsoleWrite("Body Height: " & _IEPropertyGet($oBody, "height") & @CR)

ConsoleWrite("scrollHeight: " & $oBody.scrollHeight & @CR)
ConsoleWrite("Body Height: " & _IEPropertyGet($oBody, "height") & @CR)

You two have made this point more clear for me.

I tried your code, (I didn't use "autoit"), the result:

scrollHeight: 695

Body Height: 886

In this set of pages, only the last one is short, and if there's net problem, the content of a page seems to be zero, I have to refresh......otherwise all pages seem to be the same length.

With more test I find out that different pages have the same body height(886), even if it's the last page. But scrollheight of the last page is short.

Are you sure?

Can't argue with that! How curious... my example attaching to the AutoIt forum webpage did in fact return identical values.

There are a whole bunch of these measurement properties and they are all over the board between different browsers and versions.

I like big_daddy's suggestion the best.
