Question

我已经看了半天才解决这个问题，但似乎没什么用。我想使用jQuery从一个基本上如下所示的文件中加载JSON：

[{"field_a":"1","field_b":"1000","field_c":"PRINCIPAL CASH"},
{"field_a":"2","field_b":"2000","field_c":"TRUST ASSETS"},
{"field_a":"3","field_b":"3000","field_c":" BONDS"},
{"field_a":"4","field_b":"4000","field_c":" STOCKS"}]

我想要做的是解析JSON以动态填充输入字段，所以像（请注意??字段??和??字段值是我需要知道的）：

<input id="field_a" name="field_a" value="">
<input id="field_b" name="field_b" value="">
<input id="field_c" name="field_c" value="">

<script type="text/javascript">
$(function(){

    //GET THE JSON DATA
    $.getJSON('../coreScripts/selectGeneralLedger.php', function(data) {

       //PARSE TO FIELDS
        $.each(data, function(index) {  
            $("#"+data[index].??field name??).attr("value",  data[index].??field value??);
        }) //END PARSE

     }); //End get JSON 

});
</script>

我知道如何使用数据[index] .field_a手动访问字段值，但在我的生活中不能弄清楚如何动态解析它。任何帮助，将不胜感激。

adeneo在评论中给了我以下解决方案。简单。这是脚本：

var data = [{"field_a":"1","field_b":"1000","field_c":"PRINCIPAL CASH"}, {"field_a":"2","field_b":"2000","field_c":"TRUST ASSETS"}, {"field_a":"3","field_b":"3000","field_c":" BONDS"}, {"field_a":"4","field_b":"4000","field_c":" STOCKS"}];


$.each(data, function(index, obj) {  
    $.each(obj, function(key, value) {
        $('<input />', {id: key, name:key, value:value}).appendTo('body');
    });
});

如果我不理解你，那可能就是答案。

 $.each(data, function(index) {  
     $.each(data[index] ,function(key,value){
            console.log("key :" + key + " value :" + value );
     })
 }) //END PARSE

key变量是您要求的答案。
