The plugins site is currently in development.

We've been looking to provide a higher-quality, spam-free experience at the plugins site for some time, and a major error on our part forced us to shut down the current site before we could put the new one in place. We are developing a new site, and you can follow along with its development on GitHub. For more information about this transition, including steps you can take as a plugin author to prepare, please read our post about what's going on.

postmessage


jquery postmessage plugin

Submitted by daepark on February 2, 2010 - 7:08pm

Modern browsers now support cross-window/cross-domain/cross-origin messaging
through window.postMessage.

postmessage is a simple wrapper for window.postMessage and the window message
event, for those who wish to use this feature in a more jQuery-like way.

postmessage falls back to window location hash polling for browsers that do
not support window.postMessage (i.e., IE7).

postmessage allows messaging back and forth using JSON where
window.postMessage only allows simple string-based messages.

postmessage also allows for complete request/response roundtrips using
success/error callbacks modeled after jQuery.ajax.

postmessage is tested on Safari 4, WebKit (Nightlies), Chrome 4, Firefox 3,
IE8, IE7 and Opera 10.10.

API

$.pm(options)

$.pm.bind(type, fn, [origin], [hash])

$.pm.unbind([type], [fn])


jQuery postMessage: cross-domain scripting goodness

Submitted by Ben Alman on October 23, 2009 - 11:16am

jQuery postMessage enables simple and easy window.postMessage communication in browsers that support it (FF3, Safari 4, IE8), while falling back to a document.location.hash communication method for all other browsers (IE6, IE7, Opera).
