cross-domain

问题 I'm thinking of using window.postMessage directly for cross-domain communication. If I do: postMessage() from the parent frame Load an iframe window.addEventListener("message", callback, false); from the child iframe When will the messages I posted before loading the iframe be executed? Are they guaranteed to be executed at all? Are there timing guarantees? I would like to pass a parameter from the top frame that influences the initialization of the child frame. 回答1: The postMessage()

I'm trying access a cross-domain URL via AJAX with jsonp. The problem is that the other domain (a directory listing at my university) is very old and I doubt the server supports jsonp. In Firefox, I get a "XML tag name mismatch (expected META)" error. In chrome I get a "Uncaught SyntaxError Unexpected

When I test my website with a mobile connection, the scr-attributes path is changed from src="http://example.com/get_image.php to src="http://1.1.1.1/bmi/example.com/get_image.php , I guess that has something to do with my mobile internet provider.
