using optional data arg to $.getJSON with jsonp callback

using optional data arg to $.getJSON with jsonp callback


I like passing query string params to $.getJSON as an array using the
optional data argument because it's more readable. However when using
a jsonp callback parameter it gets encoded to callback=%3F, causing it
to fail. Any way to accomplish this without modifying jquery?
This patch to jquery made it work:
