问题:

I am trying to load coffee script inside a sample.coffee file along with the coffee-script.js file and perform some simple operations on the HTML. But i am not able to load the sample.coffee file.

<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml">
  <head>
    <title></title>
    <script src="sample.coffee" type="text/coffeescript"></script>      
    <script src="coffee-script.js" type="text/javascript"></script>
  </head>
  <body>
  </body>
</html>

Here is the coffeescript code inside sample.coffee

message = "Welcome to Coffeescript"
alert message

I referred the blog http://forgivingworm.wordpress.com/2010/09/27/running-coffeescript-in-browser/

I trying to run this in MVC4 project on .cshtml. So I am running under MS world.

I am not sure if this is possible or not? any insight into this would be greatly appreciated.

I dont think this will work like you tried it. You will need something like requirejs and the coffeescript loader at https://github.com/jrburke/require-cs.

However I would strongly discourage this and rather have it compiled before loading into the browser (require.js is encouraged though). You might find grunt.js helpful for "building" your app before deploying.

I am able to solve this issue by using the CoffeeSharp http://tomlokhorst.github.com/CoffeeSharp/ It gives handler for .coffee files also converts the coffeescript to javascript on the browser.

Also I am able to compile the coffeescript to javascript during the build event itself which solves deployment and performance related issues.

That html works fine for me. I used the coffee-script.js found here: https://cdn.rawgit.com/jashkenas/coffeescript/1.11.1/extras/coffee-script.js and my sample.coffee is:
