jQuery getJSON按ID自动对我的数据进行排序

这是一个关联数组：顺序无关紧要。以下JSON对象是等效的：

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

如果需要排序，则应在JSON中嵌入一个数组：

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

用法示例：

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