The behaviour can be seen in this little snippet (execute it as a global script):
var name = {};
name.FirstName = 'Tom';
alert(name.FirstName);
The alert yields undefined
in Chrome but works in IE and Firefox. I also get a weird value when I do
alert(name);
window.name has a special purpose, and is supposed to be a string. Chrome seems to explicitly cast it to a string, so var name = {};
actually ends up giving the global variable name
(i.e. window.name
) a value of "[object Object]"
. Since it's a primitive, properties (name.FirstName
) won't "stick."
To get around this issue, don't use name
as a global variable.
