Jquery getJSON通过id自动排序我的数据

{
    "3" : "Danie Beach","1" : "Miami","2" : "Weston"
}

{
    "1" : "Miami","2" : "Weston","3" : "Danie Beach"
}

如果您需要订购,您应该在JSON中嵌入一个数组：

{
    "beaches" : [
        {"key" : "3","value" : "Danie Beach"},{"key" : "1","value" : "Miami"},{"key" : "2","value" : "Weston"}
    ]
}

使用示例

jQuery.ajax({
    ...
    dataType: 'json',success: function(data) {
        jQuery.each(data.beaches,function(i,beach) {
            alert(i+': beach['+beach.key+'] = '+beach.value);
        });
    }
});
