how to get a IE tag value by class name ?

[Sanchezu]

Hi.

I'm new to autoit, but I have some scripting experience.

I'm trying to get the value of a DIV tag from a html page. This DIV tag has no "id" or "name" attributes so I can't use _IEGetObjByName or _IEGetObjById.

My only option is to search the DIV tag by "class" attribute....

If anyone can help me with this, thanks in advance.

This is the code I'm using:

#include <IE.au3>
$oIE = _IECreate ("http://www.test.com", 0, 0, 1, 0)

$tags = $oIE.document.GetElementsByTagName("div")
For $tag in $tags
    $class_value = $tag.GetAttribute("class")
    If $class_value = "levelBar" Then
        MsgBox(0, "Level: ", "Level found :)")
    EndIf
Next

_IEQuit ($oIE)

I get no msg box, so I'm wondering why it cannot find the div tag with class attribute ="levelBar"

IE has problems with that func. use className instead:

$class_value = $tag.className

[Sanchezu]

that worked

thanks a lot

You can retrieve the Tagname by _IETagNameGetCollection, look it up in the help

I used the same code and my problem is that I can put any value in the if $class_value = "any value" then msgbox and it will launch the msgbox... Can somebody explain that to me please?

Use

If String($class_value) = "levelBar" Then

If there is no Classname, 0 is returned. This forces a numeric comparison instead of the string one you want... it converts your string to 0 and 0 = 0.

Thank you (:

Is there anyway to click on a button when I get his class? I've just tried with _IEAction but it doesn't works... But I'm not sure this is possible

Assuming you want to click the DIV you were searching for above (though most buttons are <inputs>)

#include <IE.au3>
$oIE = _IECreate ("http://www.test.com", 0, 0, 1, 0)
 
$oCorrectObj = ""

$tags = $oIE.document.GetElementsByTagName("div")
For $tag in $tags
$class_value = $tag.GetAttribute("class")
If string($class_value) = "levelBar" Then
    $oCorrectObj = $tag

MsgBox(0, "Level: ", "Level found :)")
    ExitLoop

EndIf
Next
 
If IsObj ( $oCorrectObj ) Then
 
_IEAction ($oCorrectObj, "click")


EndIF


_IEQuit ($oIE)

edit: just realized this is a super old post, but the same structure can be used for whatever your element is

Yep that's what I've tried but it didn't work :/

bling8d ... what web page are you attempting to interact with. I can take a look at it and see how to help you?

[bling8d]

It's a very well known website and I guess nobody here will answer me If I'd give it x)

_IENavigate($object, 'javascript:document.querySelector(".classname").href')

easiest method is by far the above. my one lline example simply evals javascript to select the class then returns the href. i know this posst is old but i figured someone might bee interested to know this can be done in one line
