| 9 | * Non-jQuery fork by Jeff Lee |
| 10 | * |
| 11 | * This fork consists of the following changes: |
| 12 | * 1. Basic code cleanup and restructuring, for legibility. |
| 13 | * 2. The `postMessage` and `receiveMessage` functions can be bound arbitrarily, |
| 14 | * in terms of both function names and object scope. Scope is specified by |
| 15 | * the the "this" context of NoJQueryPostMessageMixin(); |
| 16 | * 3. I've removed the check for Opera 9.64, which used `$.browser`. There were |
| 17 | * at least three different GitHub users requesting the removal of this |
| 18 | * "Opera sniff" on the original project's Issues page, so I figured this |
| 19 | * would be a relatively safe change. |
| 20 | * 4. `postMessage` no longer uses `$.param` to serialize messages that are not |
| 21 | * strings. I actually prefer this structure anyway. `receiveMessage` does |
| 22 | * not implement a corresponding deserialization step, and as such it seems |
| 23 | * cleaner and more symmetric to leave both data serialization and |
| 24 | * deserialization to the client. |
| 25 | * 5. The use of `$.isFunction` is replaced by a functionally-identical check. |
| 26 | * 6. The `$:nomunge` YUI option is no longer necessary. |
