<!-- The <EMBED> element is wrapped inside a <DIV>, which has both a 'load'
|
|
and a 'message' event listener attached. This wrapping method is used
|
|
instead of attaching the event listeners directly to the <EMBED> element to
|
|
ensure that the listeners are active before the NaCl module 'load' event
|
|
fires. This also allows you to use PPB_Messaging.PostMessage() (in C) or
|
|
pp::Instance.PostMessage() (in C++) from within the initialization code in
|
|
your NaCl module.
|
|
|
|
The src points to a manifest file, which provides the Native Client plug-in
|
|
a mapping between architecture and NaCl Executable (NEXE).
|
|
|
|
We use a non-zero sized embed to give Chrome space to place the bad plug-in
|
|
graphic, if there is a problem.
