Question

我从API获取数据但它没有出现在我的下拉列表中。

如果我与?act=showprovince回应，结果就在那里。

                        province = province + '';
                        $(id).append(province);
                    });
            },
            error:function(){

我已经检查了您的代码，所有问题都在 JavaScript 函数loadProvinsi()的这一行中：

province = '<option value="'n['province_id']'">'+n['province']+'</option>';

您错过了两个' + '标志！

所以正确的代码就像：

province = '<option value="'+n['province_id']+'">'+n['province']+'</option>';

其余代码看起来没问题，通过这两个小的更改下拉列表显示省

如果您可能需要完整的javascript函数，loadProvinsi()将如下所示：

function loadProvinsi(id){
    $('#oricity').hide();
    $('#descity').hide();
    $(id).html('loading...');
    $.ajax({
        url:'process.php?act=showprovince',
        dataType:'json',
        success:function(response){
            $(id).html('');
            $province = '';
                $.each(response['rajaongkir']['results'], function(i,n){
                    province = '<option value="'+n['province_id']+'">'+n['province']+'</option>';
                    province = province + '';
                    $(id).append(province);
                });
        },
        error:function(){
                $(id).html('ERROR');
        }
    });
}
