getElementById doesn't return anything

[BreakTheWind]

Hey!

I've been looking at forums for hours but I can't get getElementById to work.

My code:

Code: Select all

^!q::

text := pwb.document.getElementById("DV_NUTRIENT_77").innertext

msgbox %text%

I'm trying to get the protein value from a nutritional website for a certain type of food.

This is the HTML:

Code: Select all

<div class="nf4 left" style="width:31px;">
<span id="DV_NUTRIENT_77">88%</span>
</div>

Why is this not working?

Hope that's not all of your code?!
That is working fine for me ...

Code: Select all

F1::
    pwb := ComObjCreate( "InternetExplorer.Application" )                       ; Create an IE object 
    pwb.Visible := true                                                         ; Make the IE object visible 
    pwb.Navigate("https://autohotkey.com/board/topic/68594-get-element-help/")  ; Navigate to a webpage 
    while, pwb.busy
      sleep, 10
    MsgBox, % var := pwb.document.getElementById("mqbutton").innertext
    Return

Thanks, that did work.
I did saw many examples creating the object first, but I saw one that had "pwb" that didn't create an object, so I thought its a variable that creates its own object and does everything automatically, but I was very wrong. It works now, thanks!
I'm not sure how I failed to do it for so much time.

You should definitely add the below added code, otherwise you'll end up with multiple remaining IE instances (In case you decide to run that thing in "stealth" mode).

[...]
MsgBox, % var := pwb.document.getElementById("mqbutton").innertext "`n" title
Sleep, 500
pwb.quit() ; quit IE instance
Return
