New issue 1798 by [email protected]: TypeError not (properly?) raised
http://code.google.com/p/v8/issues/detail?id=1798
While developing an internal project based on V8/PyV8 I identified a
strange behavior in V8. Following the sample html page I used for my test
<html>
<body>
<script>
var a = 1;
alert("alert(a)");
alert(a);
alert("alert(doc.nonexistent)");
alert(doc.nonexistent);
alert("alert(doc.nonexistent.a)");
alert(doc.nonexistent.a);
</script>
</body>
</html>
When the script is executed I can observe this output
[2011-10-29 21:33:42] [Window] Alert Text: alert(a)
[2011-10-29 21:33:42] [Window] Alert Text: 1
[2011-10-29 21:33:42] [Window] Alert Text: alert(doc.nonexistent)
[2011-10-29 21:33:42] [Window] Alert Text: None
[2011-10-29 21:33:42] [Window] Alert Text: alert(doc.nonexistent.a)
Traceback (most recent call last):
[..]
TypeError: TypeError: Cannot read property 'a' of undefined ( @ 10 : 22 )
-> alert(doc.nonexistent.a);
Now I would expect a TypeError exception raised even when trying to
referencing doc.nonexistent but I see it does not happen and the alert
function simply returns without raising it. Is it the way it should work or
is it a bug?
Thanks and regards,
Angelo
