Coffeescript undefined variable

Question

I have the following coffeescript:

  $("#complete").click ->
    bootbox.dialog "Remember, if you complete the workorder you won't be able to add labor and materials.", [
      label: "Complete"
      class: "btn-success"
      callback: ->
        $("td").filter(':contains("ID:")').each ->
          woid = $(this).nextAll().text()
        $.update "/workorders/" + woid,
         workorder:
           wostatus_id: 232
    ,
     label: "Cancel"
      class: "btn-danger"
      callback: ->
        return 'false'
    ]

When it runs, I get this in the browser console:

Uncaught ReferenceError: woid is not defined

Thanks for the help!

Variables are scoped to the function where you first assign to them. To make woid available, initialize it to null outside your filter callback:

    woid = null

    $("td").filter(':contains("ID:")').each ->
      woid = $(this).nextAll().text()
    $.update "/workorders/" + woid,
     workorder:
       wostatus_id: 232

And as always, check your compiled JavaScript when debugging. The answer will usually be quite obvious.
