jquery non funziona correttamente, senza errori segnalati

Question

Sto lavorando su un codice jQuery che ha una forma

• lista dei paesi a discesa
• Stati Uniti, stato nell'elenco a discesa
• non usa casella di testo di stato

L'obiettivo è quello di avere un menu a discesa Paese,

Se un utente seleziona USA allora verrà mostrato l'elenco di stato USA e nascondere l'altro ingresso del testo di stato.

Se un utente seleziona un paese diverso da allora gli Stati Uniti allora dovrebbe nascondere l'elenco dello stato USA e mostrare la casella di testo di input Stato

Questa quasi funziona correttamente con il mio codice qui sotto a meno che ci sia un problema.

Il mio codice nasconderà l'elenco a discesa Stato USA, se si seleziona un paese non-USA. Tuttavia, se si seleziona gli USA, mostrerà l'elenco a discesa Stato che è grande, ma non riesce a nascondere la casella di testo di stato. Io non riesco a capire il motivo per cui, ho inviato un codice completo esempio di lavoro in modo da cann vedere il problema dal vivo se si cura di guardare si trova qui http://jsbin.com/alige

Qualsiasi aiuto sarebbe molto apprezzato.

PS) La ragione di che necessitano di questo codice in più con il cambiamento grilletto è perché a volte un utente già dispone di un paese / stato salvato in un database e quando caricare la pagina di un paese e lo stato sarà pre-selezionati in modo che po ' di codice si assicura che non necessita di un cambiamento / click per renderlo aggiornare il caricamento della pagina.

Ecco il codice.

Il jquery javascript

  $(document).ready(function () { 
    $("#otherstate").hide(); 
    $("#country").trigger("change");

    } else { 
      $("#usstate").show(); 
      $("#otherstate").hide();     
    } 
  });

Answer 1

E 'perché l'ID per la casella di testo è othstate e nello script si nasconde otherstate .

Answer 2

la tua casella di immissione testo è id="othstate" ma nel codice ti riferisci ad essa come $('#otherstate')
