problem in detecting the embeded node by javascript?

[vishnumurthy prabhu]

I have developped nacl application as given in examples and tried to
embed in the html document with the help of embed tag. The problem is
inorder to make call the to native client module via javascript, I
need to have access to the embeded node which is made possible by
getElementById(<id of embeded tag>).
I am doing so by calling the a function onload event as given in few
of the examples which comes along with nacl-sdk. But it returns
blank(getelementbyid). actual code snippet is as follows:
javascript:
var global_stack=null;
function onObjLoad()
{
global_stack=document.getElementById('mystack');
alert(global_stack);
}
in body of HTML doc, I have:

var nexes = 'x86-32: stack.nexe\n';
contentDiv.innerHTML = '<embed name="nacl_module" '
+ 'id="mystack" '
+ 'width=0 height=0 '
// + 'nexes="' + nexes + '" '
+ 'type="application/x-nacl-srpc" '
+ 'onload="onObjLoad()" />'; -------(1)
document.getElementById('mystack').nexes = nexes;onObjLoad(); -----
(2)

(1) value of global_stack=[Object embedElement]
(2)global_stack=
It is blank. so, I dont have access to nacl module. can any one tell
what is the problem?

The problem is probably bug #500: http://code.google.com/p/nativeclient/issues/detail?id=500

Take a look on "hello, world" example: http://code.google.com/p/nativeclient-sdk/source/browse/trunk/src/examples/hello_world/hello_world.html

Looks like your sel_ldr_bin is expired. Try to update it.

Looks like you are trying to use external NaCl plugin (probably remains of some previous experiments?). That's why I've asked about:version . Correct version looks like this:

Google Chrome	6.0.427.0 (Official Build 49010)
WebKit	534.1
V8	2.2.12
User Agent	Mozilla/5.0 (X11; U; Linux x86_64; en-US) AppleWebKit/534.1 (KHTML, like Gecko) Chrome/6.0.427.0 Safari/534.1
Command Line	/opt/google/chrome/google-chrome --enable-nacl       --internal-nacl --enable-gpu-plugin

 

Note: you need version 6.x and must make sure --enable-nacl flag is there (--internal-nacl and --enable-gpu-plugins are added automatically).

[David Springer]

It's possible that you have an instance of the old FireFox plugin for NaCl installed.  You will have to uninstall it.  Then, as Victor correctly points out, run Chromium with --enable-nacl.

If you are on a Linux computer, make sure that you have hardware 3D acceleration turned on, otherwise the 3D examples will not work.
