I tried to enumerate properties of XMLHttpRequest but got an error:

Error: Permission denied for <http://192.168.122.199> to get
property
XMLHttpRequest.channel

I simply skipped in the loop in my code that property by:

if (k == "channel") continue;

I wonder if there is a way to detect the permission of properties
similar to this:

/*WRONG code*/
if (xhr.channel) {
accessable = true;
}else{
accessable = false;
}

I tried to enumerate properties of XMLHttpRequest but got an error:

I've tried that too, and gotten similar errors in Mozilla Firefox.
Annoying.

Either wrap the access, e.g. `s = xhr[name]` in a try/catch or use a
map of only the things you care about. E.g.

var importantKeys = {
method : true,
async : true,
status : true
// etc.
};

You'll probably want a new function either way.
