Prevent site directory from being displayed

I have a subdomain on which I have put up all the js code for my webiste to interact with another application. For eg: at code.example.com

Whenever, the user types this address,code.example.com, all the conte开发者_C百科nts of the directory are listed. How do I prevent this thing? I do not have nay index.html or index.aspx here.
