Question

I am trying to use jQuery with CoffeScript. I was following the instructions form a blog which indicated to use $ -> or jQuery -> instead of .ready() . I played around with the code a bit but I can’t seem to understand what I am getting wrong. Just trying to learn a little bit.

Here is the code that works in jQuery:

$(document).ready( function() {
$("span.today").closest("td").css("background-color", "#7792ad")
});

Here is what I was expecting to work in CoffeScript:

$ ->
$("span.today").closest("td").css("background-color", "#7792ad")

It doesn’t work though.

Answer 1

Try this:

$ ->
    $("span.today").closest("td").css("background-color", "#7792ad");

A general principle is that many unnecessary parentheses and braces can be dropped because indention can be used instead of braces to denote blocks of code
