cocos2d-x JavaScript
#1

Hi everyone,
I am using cocos2dx html5 in window phone 8 javascript app template.
When using plist or tmx assets, it throws error:

XMLHttpRequest cannot load file:///res/Enemy.plist. Cross origin requests are only supported for HTTP.

How can i avoid it? Thanks!

The files need to be loaded from web severs.
