循环使用多个对象的 json

Question

我有一些 json 代码，其中包含多个对象，如下所示：

这些是对象内的值：

这是 json 代码：

[{"pk_records_id":"34","record_artist":"Bouncing Souls","record_title":"How I Spent My Summer Vacation","record_added_date":"2011-05-05 17:36:34","record_category":"punkrock","record_price":"11.00","record_cover_link":"img\/Bouncing Souls-How I Spent My Summer Vacation.jpg","record_amount_sold":null,"record_amount_stock":"400","record_description":"A great follow-up to Hopeless Romantic"},{"pk_records_id":"4","record_artist":"Descendents","record_title":"Everything Sucks","record_added_date":"2011-03-11 00:00:00","record_category":"punkrock","record_price":"12.00","record_cover_link":"img\/descendents_everything_sucks.jpg","record_amount_sold":"3124","record_amount_stock":null,"record_description":null}]

这是我尝试使用的代码，所以我能够检索值（显然）：

success: function(obj_records){
    $.each(obj_records, function(index, value) {
        alert(obj_records.index.pk_records_id); 
    });             
} 

但这不起作用。我怎样才能检索数据？

编辑：

如果我使用此代码，我会为 json 代码中的每个字符获得一个数组。

$.each(obj_records, function(index, value) {        
    alert(index + " : " + value);     
});  

Answer 1

尝试使用

for (var i=0; i<json.length; i++) {
   alert("JSON Data: " + json[i].pk_records_id);
  // you need to write each key name here
}

Answer 2

从表面上看，您访问的结果不正确。

尝试：

success: function(obj_records){
    $.each(obj_records, function(index, value) {
        alert(value.pk_records_id); 
    });             
} 

Answer 3

我不确定（没有地方测试它），但我认为你想要：

success: function(obj_records){
    $.each(obj_records, function(index, value) {
        alert(value.pk_records_id); 
    });             
} 

Answer 4

我相信您想要的是这样的：

success: function(obj_records){
    $.each(obj_records, function(index, value) {        
        alert(value.pk_records_id);     
    });             
} 

函数头内的 value 参数是您要循环的 obj_records 数组的单个对象。
