使用Google Chrome V22将数据从CouchDB复制到PouchDB，以便在Windows 7上进行离线存储

Question

I am trying to replicate data from CouchDB to PouchDB for offline storage using the code to pull data from CouchDB:

db.replicate.from('http://test.iriscouch.com/todo','idb://todo', function (err, changes) {
if (err) {
    console.log(err);
}
else {
    console.log(changes);
}});
$scope.loadTodos(response.rows);

I get these errors:

• Failed to load resource: the server responded with a status of 405 (Method Not Allowed)
• XMLHttpRequest cannot load http://test.iriscouch.com/todo/ . Origin null is not allowed by Access-Control-Allow-Origin.
• Uncaught TypeError: Cannot call method 'id' of undefined

Is there something I'm not doing correct?

要使PouchDB与CouchDB通信，它需要在同一个域上运行，或者需要在Pouch和Couch之间安装CORS-Proxy，这是由于浏览器强制实施的原始策略，CouchDB的下一个版本将有希望本地支持这个，但同时对于一个生产网站，我会发现最简单的方法是使用nginx让小袋和沙发在同一个域上运行
