Can't render a texture for WebGL plane

Can't render a texture for WebGL plane

I have already learned how can I add some objects in WebGL, rotate them.

The source code of my WebGL app: http://pastebin.com/dgpyMv0j
When I launch Chrome debugger, it gives me such an erros:
PS I've tried to search in web some info, but there isn't much information
for my issue, just few links.
