Handle spine ajax errors with jQuery .. by Ian White

ajax_error.js.coffee

Handle global ajax errors with jQuery:
$(document).ajaxError (xhr, status, error) =>
  console.log("Global ajaxError", arguments)
  if xhr.status is 403
    window.location = "http://backend.myapp.com/login"


Handle individual jQuery ajax requests:
$.ajax(
  url: url
).done((result, status, xhr) =>
  # The request was successful
  @user = result.user
).fail((xhr, status, error) ->
  # The request failed, check for a 403 error (or any response code) here
  if xhr.status is 403
    window.location = "http://backend.myapp.com/login"
)


Handle ajax errors on a specific Spine Model:
Person.bind "ajaxError", (record, xhr, settings, error) =>
  console.log("Person", "ajaxError", arguments)
  if xhr.status is 403
    window.location = "http://backend.myapp.com/login"
