javascript - 使用 jquery $.each 解析具有多维数组值的 json

Question

我想使用 jquery 解析 json 值，我无法使用 $.each 获取所有值，但我可以获取密钥。我不知道如何解析这些值。我的项目中使用了以下代码。所以以下是我需要解析它的json。

{
    "0": {
        "Date": "2013-09-05 03:56:30"
    },
    "1": {

    "34": {
        "Category": {
            "id": "2",
            "parent_id": null,
            "name": "Education",

        }
    }
}


$.getJSON("http://demourl/something?date=0000-00-00",function(data){

                                     $.each(data, function(i,value){
                                          alert(i);
                                          alert("city"+value.City.id);-->i cannot get the city or category values
                                            });




                                     });

你说得不够多，但如果你试试这个，你会明白的

$.each(data, function(k, v){
    if('Date' in v) console.log('Date : ' + v.Date);
    if('Category' in v) console.log('Category : ' + v.Category.name);
    if('City' in v) console.log('City : ' + v.City.cityname);
});

检查这个例子。
