I've got a basic version of globally-scoped, cross-domain code-splitting up and running that uses simple script-tags for the cross-domain load right now.</pre><pre> Re: <script> tag error reporting. In my investigations, this has been particularly bad and highly variable across browsers. I came away with three conclusions: 1. onload or onreadystatechange works across all browsers to detect a successful load, but it's moot because you can use JSONP callbacks to do this. 2. onerror works some of the time in some of the browsers. It fails on various combinations of resolve errors, error status codes and other failure conditions. For all browsers (except Opera) that don't support it directly, It can be emulated with onreadystatechange/onload and lack of a JSONP callback. 3. Opera can't detect that a script failed to load in any way that I've found: none of window.onerror, script.onerror, script.onreadystatechange will fire when the script fails to load. Matt.
