Display Form Input Value With CoffeeScript in Rails

Question

Original Question: I'm working towards validation of a user's email with a regular expression after the event of 'focusout' in javascript, but for right now I'm trying to simply get to the point where I can grab the value that was inputted into the field:

code so far:

$(document).on "page:change", ->
    $user_email = $('#user_email_form')

    $user_email.on 'focusout', ->
        alert($user_email.val)

What I want this to do is simply display the text that was entered into an alert box, but instead it is displaying a whole bunch of javascript in the alert box.

Answer

$(document).on "page:change", ->

    $(".phone_form").mask("(999) 999-9999")
    $(".ssn_form").mask("999-99-9999");

    $('#user_email_form').on 'focusout', ->
        alert($(@).val())

You need to call val() as a function as so: $user_email.val()

Also, when you do .on, you get the target as this, so you can just do this.

$user_email.on 'focusout', ->
  val = $(@).val()
