Follow-up Comment #23, bug #37223 (project gnash):
>From more testing and a hint from Gnash's `Function.call()` implementation
<http://git.savannah.gnu.org/cgit/gnash.git/tree/libcore/asobj/Function_as.cpp?id=9229f6fa59061eb930179c6f6a616be541d1139f#n159>,
I found that the correct `this` object inside ExternalInterface
callback registered with `undefined` or `null` instance is, in fact,
ActionScript's *`_global` object*.
I have made a semi-automated test SWF/HTML for verifying this aspect of
ExternalInterface, attached as `js2flash-nothis.zip`.
This is text output from `js2flash-nothis.html` on browser with Flash Player:
PASSED: Flash should properly register nullthis_call ExternalInterface
callback
PASSED: Flash should properly register undefinedthis_call ExternalInterface
callback
PASSED: ExternalInterface should be available
PASSED: nullthis_call ExternalInterface callback registration should not fail
PASSED: undefinedthis_call ExternalInterface callback registration should not
fail
PASSED: nullthis_call ExternalInterface callback should be called
PASSED: this pointer inside nullthis_call should be equal to undefined value
PASSED: this pointer inside nullthis_call should be equal to null value
PASSED: this pointer inside nullthis_call should not strictly equal to
undefined value
PASSED: this pointer inside nullthis_call should not strictly equal to null
value
PASSED: Appending this pointer inside nullthis_call to empty string should
give "undefined" string
PASSED: this pointer inside nullthis_call should be strictly equal to _global
object
PASSED: undefinedthis_call ExternalInterface callback should be called
PASSED: this pointer inside undefinedthis_call should be equal to undefined
value
PASSED: this pointer inside undefinedthis_call should be equal to null value
PASSED: this pointer inside undefinedthis_call should not strictly equal to
undefined value
PASSED: this pointer inside undefinedthis_call should not strictly equal to
null value
PASSED: Appending this pointer inside undefinedthis_call to empty string
should give "undefined" string
PASSED: this pointer inside undefinedthis_call should be strictly equal to
_global object
PASSED: There should be 19 tests run
You'd see that all checks were passed.
