// About: Support and Testing
//
// Information about what version or versions of jQuery this plugin has been

// jQuery Versions - 1.3.2
// Browsers Tested - Internet Explorer 6-8, Firefox 3, Safari 3-4, Chrome, Opera 9.
//
// About: Release History
//
// 0.5 - (9/11/2009) Improved cache-busting

// I couldn't get window.postMessage to actually work in Opera 9.64!
has_postMessage = window[postMessage] && !$.browser.opera;
// Method: jQuery.postMessage
//
// This method will call window.postMessage if available, setting the
// targetOrigin parameter to the base of the target_url parameter for maximum
// security in browsers that support it. If window.postMessage is not available,
// the target window's location.hash will be used to pass the message. If an
// object is passed as the message param, it will be serialized into a string
// using the jQuery.param method.
//
// Usage:
//
// > jQuery.postMessage( message, target_url [, target ] );
//
// Arguments:
//
// message - (String) A message to be passed to the other frame.
// message - (Object) An object to be serialized into a params string, using
// the jQuery.param method.
// target_url - (String) The URL of the other frame this window is
// attempting to communicate with. This must be the exact URL (including
// any query string) of the other window for this script to work in
// browsers that don't support window.postMessage.
// target - (Object) A reference to the other frame this window is
// attempting to communicate with. If omitted, defaults to `parent`.
//
// Returns:
//
// Nothing.
$[postMessage] = function( message, target_url, target ) {
if ( !target_url ) { return; }
// Serialize the message if not a string. Note that this is the only real
// jQuery dependency for this script. If removed, this script could be
// written as very basic JavaScript.
message = typeof message === 'string' ? message : $.param( message );
// Default to parent if unspecified.
target = target || parent;
if ( has_postMessage ) {
// The browser supports window.postMessage, so call it with a targetOrigin
// set appropriately, based on the target_url parameter.
target[postMessage]( message, target_url.replace( /([^:]+:\/\/[^\/]+).*/, '$1' ) );
} else if ( target_url ) {
// The browser does not support window.postMessage, so set the location
// of the target to target_url#message. A bit ugly, but it works! A cache
// bust parameter is added to ensure that repeat messages trigger the
// callback.
target.location = target_url.replace( /#.*$/, '' ) + '#' + (+new Date) + (cache_bust++) + '&' + message;
}
};
// Method: jQuery.receiveMessage
//
// Register a single callback for either a window.postMessage call, if
// supported, or if unsupported, for any change in the current window
// location.hash. If window.postMessage is supported and source_origin is
// specified, the source window will be checked against this for maximum
// security. If window.postMessage is unsupported, a polling loop will be
// started to watch for changes to the location.hash.
//
// Note that for simplicity's sake, only a single callback can be registered
// at one time. Passing no params will unbind this event (or stop the polling
// loop), and calling this method a second time with another callback will
// unbind the event (or stop the polling loop) first, before binding the new
// callback.
//
// Also note that if window.postMessage is available, the optional
// source_origin param will be used to test the event.origin property. From
// the MDC window.postMessage docs: This string is the concatenation of the
// protocol and "://", the host name if one exists, and ":" followed by a port
// number if a port is present and differs from the default port for the given
// protocol. Examples of typical origins are https://example.org (implying
// port 443), http://example.net (implying port 80), and http://example.com:8080.
//
// Usage:
//
// > jQuery.receiveMessage( callback [, source_origin ] [, delay ] );
//
// Arguments:
//
// callback - (Function) This callback will execute whenever a <jQuery.postMessage>
// message is received, provided the source_origin matches. If callback is
// omitted, any existing receiveMessage event bind or polling loop will be
// canceled.
// source_origin - (String) If window.postMessage is available and this value
// is not equal to the event.origin property, the callback will not be
// called.
// source_origin - (Function) If window.postMessage is available and this
// function returns false when passed the event.origin property, the
// callback will not be called.
// delay - (Number) An optional zero-or-greater delay in milliseconds at
// which the polling loop will execute (for browser that don't support
// window.postMessage). If omitted, defaults to 100.
//
// Returns:
//
// Nothing!
$.receiveMessage = p_receiveMessage = function( callback, source_origin, delay ) {
if ( has_postMessage ) {
// Since the browser supports window.postMessage, the callback will be
// bound to the actual event associated with window.postMessage.
if ( callback ) {
// Unbind an existing callback if it exists.
rm_callback && p_receiveMessage();
// Bind the callback. A reference to the callback is stored for ease of
// unbinding.
