Question

given the following:
where data is a string received as an AJAX value and data has a value of ‘good’:

console.log data          # good
console.log typeof data   # string
console.log typeof 'data' # string

if data is 'good'
  console.log 'test' # NOTHING!!!

I don’t understand…

makes me want the good ol’ JavaScript back…

A more complete example after a suggestion:

The following does not work either…

  $('#profile_slug').keyup(()->
    if $(this).val() != original_slug
      value = encodeURIComponent $(this).val()
      console.log value
      $.get('/live_validate/slug?slug='+value, (data)->

        console.log data
        console.log typeof data
        console.log typeof 'data'

        `
        if (data == 'good') {
          console.log('test');
        }

       `

update 2

oddly enough:

console.dir data
console.dir 'good'

good
No Properties

good
No Properties

update 3

controller

  if @slug.nil?
    @message = "good"
  else
    @message = "bad"
  end

view

!= @message

coffeescript

new_data = data.replace /^\s+|\s+$/g, ""

result

same sh*t.

update 4 + answer

This code ended up being what I needed, at first it didn’t work quite well with everything else I had going on, but it is the final piece in the puzzle, allowing me to make sure there are no invisible spaces before or after the received string.

    $.get('/live_validate/slug?slug='+value, (data)->
        # console.log data

        stripped_data = data.replace /^\s+|\s+$/g, ""

        # console.log encodeURIComponent data
        # console.log (data.charCodeAt(i) for i in [0...data.length])       


        if stripped_data is 'good'
          $('#profile_slug').addClass('valid-field')
          $('#profile_slug').removeClass('invalid-field')
        else if stripped_data is 'bad'
          $('#profile_slug').addClass('invalid-field')
          $('#profile_slug').removeClass('valid-field')

Answer 1

It ended up being an invisible character at the end of the ajax response string… thanks all!
