Jsonを使用してコードイグナイタービューにデータをディップスレイしようとしています。戻ります
[{"id": "5"、 "cityname": "Manegerial Estate"}、{"id": "6"、 "cityname": "Kilimani"}、{"id": "12"、 "cityname" :"職人"}]
コードの一部。オプション選択で返されたalueをエコーするにはどうすればよいですか。上記のようにselectの戻り値をエコーします
var post_url = "control_form/get_cities_by_state/"+ state_id;
$.ajax({
url: post_url,
type: "POST",
// dataType: 'json',
success: function(cities) //we're calling the response json array 'cities'
{
alert(cities);
$('#f_city').empty();
$('#f_city, #f_city_label').show();
$.each(cities,function(id,city)
{
var items=cities['id'];
alert(items);
var opt = $('<option />'); // here we're creating a new select option for each group
opt.val(id);
opt.text(city);
$('#f_city').append(opt);
});
}); //end AJAX
} else {
$('#f_city').empty();
$('#f_city, #f_city_label').hide();
}//end if
}); //end change
});
