|
* Mozilla's XMLHttpRequest is modelled after Microsoft's IXMLHttpRequest
|
|
* object. The goal has been to make Mozilla's version match Microsoft's
|
|
* version as closely as possible, but there are bound to be some differences.
|
|
*
|
|
* In general, Microsoft's documentation for IXMLHttpRequest can be used.
|
|
* Mozilla's interface definitions provide some additional documentation. The
|
|
* web page to look at is http://www.mozilla.org/xmlextras/
|
|
*
|
|
* Mozilla's XMLHttpRequest object can be created in JavaScript like this:
|
|
* new XMLHttpRequest()
|
|
* compare to Internet Explorer:
|
|
* new ActiveXObject("Msxml2.XMLHTTP")
|
|
*
|
|
* From JavaScript, the methods and properties visible in the XMLHttpRequest
|
|
* object are a combination of nsIXMLHttpRequest and nsIJSXMLHttpRequest;
|
|
* there is no need to differentiate between those interfaces.
|
|
*
|
|
* From native code, the way to set up onload and onerror handlers is a bit
|
|
* different. Here is a comment from Johnny Stenback <jst@netscape.com>:
|
|
*
|
|
* The mozilla implementation of nsIXMLHttpRequest implements the interface
|
|
* nsIDOMEventTarget and that's how you're supported to add event listeners.
|
|
* Try something like this:
|
|
*
|
|
* nsCOMPtr<nsIDOMEventTarget> target(do_QueryInterface(myxmlhttpreq));
|
|
*
|
|
* target->AddEventListener(NS_LITERAL_STRING("load"), mylistener,
|
|
* PR_FALSE)
|
|
*
|
|
* where mylistener is your event listener object that implements the
|
|
* interface nsIDOMEventListener.
|
|
*
|
|
* The 'onload', 'onerror', and 'onreadystatechange' attributes moved to
|
|
* nsIJSXMLHttpRequest, but if you're coding in C++ you should avoid using
|
|
* those.
|
|
*
|
|
* Conclusion: Do not use event listeners on XMLHttpRequest from C++, unless
|
|
* you're aware of all the security implications. And then think twice about
|
|
* it.
