1. Through IFRAME
2. Through JSONP
3. Set http header, Access-Control-Allow-Origin:*
4. Server proxy
5. nginx reverse proxy to achieve cross-domain

Anything to add?

How can we not have PHP’s powerful tool class, curl. How perfect can we achieve with this

<code>window.name</code>

Set Access-Control-Allow-Origin:* should belong to CORS

Use window.navigator for cross-domain
This solution can only be used in ie6 and ie7
because there is a bug in ie6 and ie7. That is, the navigator of the parent page and the child page are shared.

General solutions are postMessage, <code>window.name</code>, window.navigator.

postMessage is used in standard browsers.
<code>window.name</code> and window.navigator are used in ie, but the implementation of <code>window.name</code> must regularly check whether name has changed, while navigator does not exist.

feature detection The priority is postMessage, navigator, name.

See the picture below:

The mainstream ones include cors, HTML5 postmessage, josnp, and server proxy
