Bestückung auswählen mit AJAX JSON-Array

Question

Ich habe eine Anwendung, die mit SagePay (Payment Gateway) integriert werden muss.

Es gibt eine Liste von Ländern in ISO-3166-1-Format here, die ich hinzufügen möchte.

Die Liste erscheint json Daten innerhalb eines Arrays countries genannt werden:

countries = [ 
    {code: "GB", name: "United Kingdom"}, 
    {code: "AF", name: "Afghanistan"}, 
    {code: "AX", name: "Aland Islands"}, 
    // ... 
]; 

Ich habe ein select Element mit der ID country:

<select id="country"></select> 

habe ich versucht, Ajax, wie hinzuzufügen folgt diese Elemente zu meinem select Elemente auf Seite laden:

$.ajax({ 
    url: '/js/countrycodes.js', 
    type: 'POST', 
    dataType: 'json', 
    success: function(json) { 
     $.each(json, function(i, value) { 
      $('#country').append($('<option>').text(code).attr('value', name)); 
     }); 
    } 
}); 

Dies scheint nichts zu tun. Wenn ich console.log(json) im success Rückruf es nichts produziert.

Ich weiß, ein Problem ist, dass die JSON-Daten in einem Array ist, countries, aber nicht sicher, wie dies zu analysieren.

Ich habe überprüft, um sicherzustellen, ich bekomme ein HTTP 200 auf /js/countrycodes.js und dies ist zugänglich, wie auch die anderen Dateien wie jquery sind.

Jede Hilfe würde sehr geschätzt werden.

bearbeiten ist dies der Ausgang, wenn ich einige der vorgeschlagenen Antworten in meiner Konsole ausführen:

Answer 1

Hier ist eine Alternative: da Ihre Länderliste statisch ist und in einer js-Datei enthalten, die es als eine Variable deklariert, kann es nur auf Ihrer Seite in der normalen Art und Weise aufgenommen werden, ohne die Notwendigkeit für Ajax:

<select id="country"></select> 
<script type="javascript" language="text/javascript" src="/js/countrycodes.js"></script> 
<script> 
//use the countries variable which was declared in the countrycodes script file. 
$.each(countries, function(i, value) { 
    $('#country').append($('<option>').text(value.code).attr('value', value.name)); 
}); 
</script> 

Answer 2

$.ajax({ 
    url: '/js/countrycodes.js', 
    type: 'POST', 
    dataType: 'json', 
    success: function(json) { 
     $.each(json, function(i, value) { 
      $('#country').append($('<option>').text(value.code).attr('value', value.name)); 
     }); 
    } 
}); 

sollte es beheben. Sie haben einfach value. verpasst, um auf die Eigenschaften innerhalb des aktuellen Objekts in der Schleife zu verweisen. In deiner Version sind code und name nicht von irgendwo her gekommen. Sie erhalten ihre Werte nicht automatisch, sondern sind Eigenschaften von value.
