Hi,
Thanks for contacting Microsoft.
The HTML5 postMessage function provides a great way for mutually
distrusting documents (even cross-domain) to communicate securely and with high performance and reliability. Unfortunately, as reported on
Connect, the HTML5 postMessage function does not work between tabs/windows in IE8. (This limitation is an artifact of the Loosely-Coupled IE feature, in which content in different tabs/windows may run in a different
process.) Update: As of IE11, this issue has not yet been fixed.
For more information, please refer to the article below.
