goog.net.IframeIo

Abort the current Iframe request

Adds an event listener to the event target. The same handler can only be added once per the type. Even if you add the same handler multiple times using the same type then it will only be called once when the event is dispatched.

Invokes a callback function when this object is disposed. Callbacks are invoked in the order in which they were added. If a callback is added to an already disposed Disposable, it will be called immediately.

Dispatches an event (or event like object) and calls all listeners listening for events of this type. The type of the event is decided by the type property on the event object.

If any of the listeners returns false OR calls preventDefault then this function will return false. If one of the capture listeners calls stopPropagation, then the bubble listeners won't fire.

Disposes of the object and its resources.

Removes listeners from this object. Classes that extend EventTarget may need to override this method in order to remove references to DOM Elements and additional listeners.

Fires all registered listeners in this listenable for the given type and capture mode, passing them the given eventObject. This does not perform actual capture/bubble. Only implementors of the interface should be using this.

Gets the callback function used to check if a loaded IFrame is in an error state.

Gets the last custom error.

Gets the last error message.

Gets the last error code.

Get the uri of the last request.

Gets the goog.events.ListenableKey for the event or null if no such listener is in use.

Gets all listeners in this listenable for the given type and capture mode.

Returns the parent of this event target to use for capture/bubble mechanism.

NOTE(chrishenry): The name reflects the original implementation of custom event target (goog.events.EventTarget). We decided that changing the name is not worth it.

Returns the last response html (i.e. the innerHtml of the iframe).

Parses the content as JSON. This is a legacy method for browsers without JSON.parse or for responses that are not valid JSON (e.g. containing NaN). Use JSON.parse(this.getResponseText()) in the other cases.

Returns the last response text (i.e. the text content of the iframe). Assumes plain text!

Returns the document object from the last request. Not truly XML, but used to mirror the XhrIo interface.

Whether there is any active listeners matching the specified signature. If either the type or capture parameters are unspecified, the function will match on the remaining criteria.

Adds an event listener. A listener can only be added once to an object and if it is added again the key for the listener is returned. Note that if the existing listener is a one-off listener (registered via listenOnce), it will no longer be a one-off listener after a call to listen().

Adds an event listener that is removed automatically after the listener fired once.

If an existing listener already exists, listenOnce will do nothing. In particular, if the listener was previously registered via listen(), listenOnce() will not turn the listener into a one-off listener. Similarly, if there is already an existing one-off listener, listenOnce does not modify the listeners (it is still a once listener).

Associates a disposable object with this object so that they will be disposed together.

Removes all listeners from this listenable. If type is specified, it will only remove listeners of the particular type. otherwise all registered listeners will be removed.

Removes an event listener from the event target. The handler must be the same object as the one added. If the handler has not been added then nothing is done.

Sends a request via an iframe.

A HTML form is used and submitted to the iframe, this simplifies the difference between GET and POST requests. The iframe needs to be created and destroyed for each request otherwise the request will contribute to the history stack.

sendFromForm does some clever trickery (thanks jlim) in non-IE browsers to stop a history entry being added for POST requests.

Sends the data stored in an existing form to the server. The HTTP method should be specified on the form, the action can also be specified but can be overridden by the optional URI param.

This can be used in conjunction will a file-upload input to upload a file in the background without affecting history.

Example form:

   <form action="/server/" enctype="multipart/form-data" method="POST">
     <input name="userfile" type="file">
   </form>
 

Sets the callback function used to check if a loaded IFrame is in an error state.

Sets whether to ignore the response from the server by not adding any event handlers to fire when the iframe loads. This is necessary when using IframeIo to submit to a server on another domain, to avoid same-origin violations when trying to access the response. If this is set to true, the IframeIo instance will be a single-use instance that is only usable for one request. It will only clean up its resources (iframes and forms) when it is disposed.

Sets the parent of this event target to use for capture/bubble mechanism.

Sets the target to be used for event.target when firing event. Mainly used for testing. For example, see goog.testing.events.mixinListenable.

Removes an event listener which was added with listen() or listenOnce().

Removes an event listener which was added with listen() by the key returned by listen().

If monitoring the goog.Disposable instances is enabled, stores the creation stack trace of the Disposable instance.

Find an iframe by name (assumes the context is goog.global since that is where IframeIo's iframes are kept).

Find an instance of the IframeIo object by name.

Handles incremental data and routes it to the correct iframeIo instance. The HTML page requested by the IframeIo instance should contain script blocks that call an externed reference to this method.

Static send that creates a short lived instance of IframeIo to send the request.

Prefix for frame names

The number of milliseconds after a request is completed to dispose the iframes. This can be done lazily so we wait long enough for any processing that occurred as a result of the response to finish.

Suffix that is added to inner frames used for sending requests in non-IE browsers
