Is there a way to check if the DOM property exist before accessing it? I'm getting error when trying to access a class which do not exist. In this example, I have a collection of anchor tags. Some anchor has className while some do not. When I loop, AutoIT throw an error on anchors which do not have className

Code with error:

Local $oTags = _IETagNameGetCollection($oResult, "A")

For $tag in $oTags
If $tag.className = "ABC" Then
; Do something
EndIf
Next

I'm looking for something like this (or any other solution)

Local $oTags = _IETagNameGetCollection($oResult, "A")

For $tag in $oTags
If $tag.isProperty(className) AND $tag.className = "ABC" Then
; Do something
EndIf
Next

Thanks.

You could add a COM error handler and set @error if the property does not exist.

_IEErrorHandlerRegister() makes this easy. Or use the latest beta that makes COM errors non-fatal.

Doesn't work needs to be ripped out of the troubleshooting lexicon. It means that what you tried did not produce the results you expected. It begs the questions 1) what did you try?, 2) what did you expect? and 3) what happened instead?
