PhantomJS and XHR Cross-domain request

[Finalfire]

Hello everybody,

I'm working a little with PhantomJS: I need a stand-alone js version to automatize some batch processing.

I've some problem about using Cross-domain XHR. Following is the source I'm using:

var x = new XMLHttpRequest();

x.onreadystatechange = function() {

console.log("I'm in with status: " + x.status);

if (x.status === 200 && x.readyState === 4) {

console.log("ciao");

}

}

x.open("GET", "http://www.google.com", true);

x.send(null);

Unfortunately I receive some messages: 

undefined:0 INVALID_STATE_ERR: DOM Exception 11: An attempt was made to use an object that is not, or is no longer, usable.

I'm in with status: 0 

Then execution of that file is still alive, doing anything.

Can someone explain me why there's this behavior? Apparently, I can use page.open() but I need to do a lot of operation on Document element and PhantomJS does not allow me to return document element from a page.evaluate(), plus I can't send arguments to page.evaluate() and I need it :( Maybe I'm wrong on last point but I tried everything, can't do anything.

Im running on Leopard 10.5.8, compiled Qt + PhantomJS with /deploy script.

Thanks to anyone,

F.

Cross-posting because the problem is about page.evaluate() function: I can't return anything from within evaluate. Is it normal? There's some hope to enhance it? I think it's a huge limitation, even if evaluate() is a sandboxed function.

Interesting idea, use the file module to create dynamic js files.  Json encode data and then use the injectjs method of a webpage .

That sounds like http://code.google.com/p/phantomjs/issues/detail?id=28.

page.evaluate can return an object just fine. See some of the
examples, find them using:

git grep '= page.evaluate'
