循环遍历动态对象 - Jquery

Question

我知道这可以很容易地完成，我只是想不通。我有一个由 SPARQL 查询生成的动态对象。它像这样返回 JSON：

data = {
    "p": { "type": "uri" , "value": "http://www.company.com/PDE/SpecGuide#MatrixColumn" } ,
    "o": { "type": "literal" , "datatype": "http://www.w3.org/2001/XMLSchema#integer" , "value": "1" } ,
    "obj": { "type": "uri" , "value": "http://www.company.com/PDE/SpecGuide#airtouch" } ,
    "lbl": { "type": "literal" , "value": "Airtouch" }
  } ,
  {
    "p": { "type": "uri" , "value": "http://www.company.com/PDE/SpecGuide#MatrixRow" } ,
    "o": { "type": "literal" , "datatype": "http://www.w3.org/2001/XMLSchema#integer" , "value": "1" } ,
    "obj": { "type": "literal" , "value": "Smooth_Paint" } ,
    "hdr": { "type": "literal" , "datatype": "http://www.w3.org/2001/XMLSchema#boolean" , "value": "true" }
  } 

我唯一关心的是键和value['value']所以我需要过滤掉其余的。最终，我正在寻找这个：

data = [
{1: {p: "http://www.company.com/PDE/SpecGuide#MatrixColumn",
     o: "1", 
     obj : "Smooth_Paint"} ,
{2 : {p: "http://www.company.com/PDE/SpecGuide#MatrixColumn",
     o: "1", 
     obj : "other_values"}
     otherKey: "more_values}
]

这让我发疯，因为我知道这并不是特别困难，但我无法弄清楚。我尝试了

的变体

$.each(data, function(key,valueObj){
   data.key = {key: valueObj.value};
   list.push(data)
});

但我最终得到了这样的变体：

{1:{key: "http://www.company.com/PDE/SpecGuide#MatrixColumn"}}
{2: {key: "1"}}
{3:{key: "http://www.company.com/PDE/SpecGuide#airtouch"}}
{4:{key: "Airtouch"}}

Answer 1

$.each() 回调中的第一个变量始终是索引。

您可以使用for...in 来获取附加到对象本身的属性hasOwnProperty()。 See more

var data = [{
    "p": { "type": "uri" , "value": "http://www.company.com/PDE/SpecGuide#MatrixColumn" } ,
    "o": { "type": "literal" , "datatype": "http://www.w3.org/2001/XMLSchema#integer" , "value": "1" } ,
    "obj": { "type": "uri" , "value": "http://www.company.com/PDE/SpecGuide#airtouch" } ,
    "lbl": { "type": "literal" , "value": "Airtouch" }
  } ,
  {
    "p": { "type": "uri" , "value": "http://www.company.com/PDE/SpecGuide#MatrixRow" } ,
    "o": { "type": "literal" , "datatype": "http://www.w3.org/2001/XMLSchema#integer" , "value": "1" } ,
    "obj": { "type": "literal" , "value": "Smooth_Paint" } ,
    "hdr": { "type": "literal" , "datatype": "http://www.w3.org/2001/XMLSchema#boolean" , "value": "true" }
  }]
  var list = [];
  $.each(data, function(index, obj){
    var newData = {}
    for(key in obj){
        if(obj.hasOwnProperty(key))
        {
            newData[key] = obj[key]['value']
        }
    }
    var data = {}
    data[list.length+1] = newData
    list.push(data)
  })
  console.log(list)
