This works:

$('#products.table tr').click ->
  $(@).toggleClass('row_selected')

This doesn't:

$('#products.table tr').live 'click', (event) ->
  $(@).toggleClass('row_selected')

Error in browser's console:

[Error] TypeError: 'undefined' is not a function (evaluating '$('#products.table tr').live')
    ready (products.js, line 10)
    fire (jquery.js, line 3049)
    fireWith (jquery.js, line 3161)
    ready (jquery.js, line 434)
    pleted (jquery.js, line 105)

What am I missing?

What am I missing?

• javascript
• jquery
• ruby-on-rails
• coffeescript
• click

live has been deprecated as of jQuery version 1.7, and Rails 3's default jQuery version is 1.9. You need to use on instead:

Try:

$(document).on 'click', '#products.table tr', (event) ->
  if ( $(@).hasClass('row_selected') )
    $(@).removeClass('row_selected')
  else
    $(@).addClass('row_selected')

or, you could use the toggleClass method as suggested in the ments as:

$(document).on 'click', '#products.table tr', (event) ->
  $(@).toggleClass('row_selected')
