Question

我在调用PHP后调用JSON编码数据：

[  
   {  
      "id":"4",
      "name":"Kg",
      "vital_sign_list_id":"3",
      "created":"2016-03-01 18:52:27",
      "modiefied":"2016-03-01 18:52:27"
   },
   {  
      "id":"5",
      "name":"Pound",
      "vital_sign_list_id":"3",
      "created":"2016-03-01 18:52:27",
      "modiefied":"2016-03-01 18:52:27"
   }
]

有两个数据，我想使用循环解码并使用 jquery 来使用数据。我怎样才能实现它？

Answer 1

尝试以下代码：

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.0.0-beta1/jquery.js"></script>
<script>
    json = '[{"id":"4","name":"Kg","vital_sign_list_id":"3","created":"2016-03-01 18:52:27","modiefied":"2016-03-01 18:52:27"}, {"id":"5","name":"Pound","vital_sign_list_id":"3","created":"2016-03-01 18:52:27","modiefied":"2016-03-01 18:52:27"}]';
    var obj = $.parseJSON( json);
    $.each(obj, function(index, val){
       alert(val.name);
       //you can access other data by using val.id, val.created etc
    });
</script>

你可以试试这种方式

＆＃13;

var data = [{"id":"4","name":"Kg","vital_sign_list_id":"3","created":"2016-03-01 18:52:27","modiefied":"2016-03-01 18:52:27"}, {"id":"5","name":"Pound","vital_sign_list_id":"3","created":"2016-03-01 18:52:27","modiefied":"2016-03-01 18:52:27"}];



for(var i = 0 ; i < data.length; i++){
  
  console.log("ID "+ i +": "+ data[i].id);
  console.log("Name "+ i +": "+ data[i].name);
  console.log("Vital "+ i +": "+ data[i].vital_sign_list_id);
  }

Answer 3

json_encode(jsonArrVar);

在你的json php文件中使用它来编码你的json数据。并在jquery中使用json.parse或eval函数解析它。
