I am trying to use Coffeescript, but I am having a problem on my web application. Its methods are not called until I reload the page.

I think that what is missing is the $(document).ready(function () { part, but I couldn't find how to do it in the web.

file_name.js (works great)

$(document).ready(function () {
  $(document).on('click', '.add_fields', function(event) {
    event.preventDefault();
    /* Act on the event */
    time = new Date().getTime()
    regexp = new RegExp($(this).data('id'), 'g')
    $(this).before($(this).data('fields').replace(regexp, time))
  });
});

file_name.coffee (doesn't work)

jQuery ->
  $('form').on 'click', '.add_fields', (event) ->
    time = new Date().getTime()
    regexp = new RegExp($(this).data('id'), 'g')
    $(this).before($(this).data('fields').replace(regexp, time))
    event.preventDefault()

How can I fix this?

• 1 Coffeescript is just fancy Javascript. "On document ready" is not a feature of Javascript language, but feature of the browser or jQuery library. So, when in doubt, just write same Javascript code with block indentation instead of curly brackets, and replacing function() with -> – metalim Commented Jun 6, 2018 at 19:53
