get object value inside function coffeescript

Question

title = ->
  $("#post_title").keyup ->
    @value

When I try to call to title() function I'm getting [object Object] .

I have to add to the function value to this code:

"<li>" + "<div class='btn-group'>" + "<a href='/en" + "/posts/preview_search/" + "?post[title]=" +  title() + "</a>" + "</div>" + "</li>"

How can I get the @value returned by the object instead of the object?

Thanks!

Answer 1

The keyup event will happen after the function returns, therefore it can't be assigned to title using the function's return value. One way would be to do whatever you need to do with title inside the function:

$("#post_title").keyup ->
  title = @value
  # use title

Answer 2

Try:

title = ->
      $("#post_title").keyup (e) ->
        $(e.target).attr 'value'
