cross-domain javascript

I am producing a javascript-based widget. Nothing complex just a few document.writes...

When I place it inline in开发者_运维技巧 the page it renders fine in all browsers. When I place it externally and load it via <script src="http://example.com/path/to/site"/> it fails to render in Firefox and IE but not Chrome.

Anyone know why and a possible workaround?

Maybe you should close it with </script> instead of XML-style.
