true false in quotes?

TheMSsForum.com: The Microsoft Software Forum

Hi,

Are there any rules for using or not using quotes around true or false.
Witness the following: (Hold the alt key and click the document)

<html>
<head>
<script language=vbs defer>

sub document_onclick()

if d1.contentEditable=true then 'doesn't work
msgbox "d1.contentEditable=true"
else
msgbox d1.contentEditable=true
end if

if d1.contentEditable="true" then 'works
msgbox "d1.contentEditable=""true"" "
else
msgbox d1.contentEditable="true"
end if

if window.event.altKey=true then 'works
msgbox "window.event.altKey=true"
else
msgbox window.event.altKey=true
end if

if window.event.altKey="true" then 'doesn't work
msgbox "window.event.altKey=""true"" "
else
msgbox window.event.altKey="true"
end if

end sub
</script>

</head>
<body>
<div id=d1 contentEditable=true>&nbsp;</div>
</body>
</html>

These all work for me...

sub document_onclick()

msgbox "typename(d1.contentEditable) is " _
& typename(d1.contentEditable) _
& " with a value of " & d1.contentEditable

if d1.contentEditable then
msgbox "1) d1.contentEditable is true"
else
msgbox "1) d1.contentEditable is not true"
end if

if cbool(d1.contentEditable) = true then
msgbox "2) d1.contentEditable is true"
else
msgbox "2) d1.contentEditable is not true"
end if

if d1.contentEditable = "true" then
msgbox "3) d1.contentEditable is true"
else
msgbox "3) d1.contentEditable is not true"
end if

end sub

The reason why your script is behaving differently is because of the
difference in types of the properties you're accessing.

contentEditable evaluates to a string, as this seems to be a rather
dynamic property. So when you want to check the value of it, you need
to enclose it in quotes and compare it as a string. But I would
recommend you to cast it to a boolean with CBool, CBool("true") =>
True. Be careful though - the cast will fail if the value of the
property cannot be evaluated as a Boolean (i.e. anything else than
true/false).

window.event.altKey, on the other hand, seems to be a real boolean,
which is why you can test it directly with True/False but not
"True"/"False".

If you dig deep enough, you'll prolly find somewhere on MSDN the type
of each property.

Good luck!

Johan
