coffeescript with jquery ajax

Question

$.ajax '/',
    type: 'GET'
    dataType: 'html' error: (jqXHR, textStatus, errorThrown) ->
        $('body').append "AJAX Error: #{textStatus}"
    success: (data, textStatus, jqXHR) ->
        $('body').append "Successful AJAX call: #{data}"

there is something wrong with the above code,I can't compile it into js

-_-|||,i found the reason , it mixed with "tab" and "space" ,so it can't work — magicshui

When using coffee-script.js, you should see compile-time errors on your browser's console. If your browser doesn't have a console, grab the Firebug Lite bookmarklet. — Trevor Burnham

The compiler gives the error

Parse error on line 3: Unexpected 'IDENTIFIER'

referring to the line

dataType: 'html' error: (jqXHR, textStatus, errorThrown) ->

The problem is simply that there's no comma (or line break) between 'html' and error. Here's the fixed code:

$.ajax '/',
    type: 'GET'
    dataType: 'html'
    error: (jqXHR, textStatus, errorThrown) ->
        $('body').append "AJAX Error: #{textStatus}"
    success: (data, textStatus, jqXHR) ->
        $('body').append "Successful AJAX call: #{data}"

I highly recommend using an editor with a built-in "Build" command, especially one that can work on selected text. It makes syntax errors a lot easier to pin down.

NetBeans is one such editor that so far I like for a free IDE. Look under tools->plugins to add the CoffeeScript plugin then right click your .coffee file and select CoffeeScript->autocompile. No need to install commandline tools.

@trevor do you recommend a particular build system for the editor? Ideally Sublime Text? Currently I am using a build system as part of a framework.

@Scoop If you're using the official CoffeeScript tmbundle with ST2, there should already be a Build command that works for your CoffeeScript.
