Question

我试图解析以下JSON：

{
"customers": [
{ "name":"joe" , "cars":[
    {"name":"honda","visits":[
        {"date":"01/30/14","Id":"201"},
        {"date":"01/30/14","Id":"201"},
        {"date":"02/12/14","Id":"109"}
        ]},
         {"name":"Nissan","visits":[
        {"date":"01/30/14","Id":"201"},
        {"date":"02/12/14","Id":"109"}
        ]}
    ]},

{ "name":"bob" , "cars":[
    {"name":"escalade","visits":[
         {"date":"01/05/14","Id":"301"},
        {"date":"01/18/14","Id":"551"}
        ]},
         {"name":"corvette","visits":[
         {"date":"01/05/14","Id":"301"},
        {"date":"01/18/14","Id":"551"}
        ]}
    ]} 
]
}

使用以下jQuery脚本：

$("document").ready(function(){

        $.getJSON("data1.json", function(json) {
    console.log(json); // this will show the info it in firebug console

            $.each(json.customers,function(customer){
        console.log(customer.name);
        console.log(customer.cars);     
    });
});

});

JSON正在控制台中传出，但我试图解析的字段是未定义的。谁能告诉我我做错了什么？

我认为这里的问题是你使用$.each，你的回调函数将接收索引作为第一个参数，值作为第二个参数，看起来你期望第一个参数是值。因此，在您当前的代码中customer将是一个索引（0，1等），而不是来自JSON的对象。

尝试将$.each来电更改为以下内容：

$.each(json.customers, function(index, customer) {
    console.log(customer.name);
    console.log(customer.cars);     
});

解析后的元素未定义
