Javascript http请求并转换为json，并与json进行比较 我想向url发出http请求，比如 这将为我提供xml 我想皈依 这个从1到json的xml可以说是json 1 现在我向url let发出一个rest请求 假设它返回一个json，假设json 2

json 1

[

现在Id是json1和json2之间的常量，我想生成一个json结果，如下所示，让我们调用json3

[
    {
        "id": "123",
        "testname": "test123",
        "name": "John Doe",
        "active": true,
        "type": "test6",
        "country":"USA",
         "state":"KA"
    }

 {
        "id": "456",
        "testname": "test564",
        "name": "Ship Therasus",
        "active": true,
        "type": "test7",
         "country":"UK",
         "state":"MA"
    }
]

现在我尝试了1和3，但2不知道该做什么，比较和结合，我不确定该做什么，如果有任何帮助将是巨大的

function fun() 
{
  var data="hello";
  $.post('http://localhost/ws/service.asmx/HelloWord',{},function(response) 
  {     data = response;
  }).error(function(){
  alert("Sorry could not proceed");
});

    return data;
}

您可以尝试以下方法：

<script>
$(document).ready(function(){
var result=[];
    var x=[{"id": "123","testname": "test123", "name": "John Doe","active": true,"type": "test6"},{"id": "456", "testname": "test564", "name": "Ship Therasus", "active": true,"type": "test7" }];
var y = [{ "id": "123", "country": "USA", "state": "KA", "age": 24,"group": "g1"},{ "id": "456", "country": "UK", "state": "MA", "age": 28, "group": "G2"}];
for (i in x){
    for (j in y){
      if(x[i].id == y[j].id){

          result.push($.extend(x[i], y[j]));

          }
       }
   }  
console.log(result);

});
</script>

$（文档）.ready（函数（）{
var结果=[]；
var x=[{“id”：“123”，“testname”：“test123”，“name”：“John Doe”，“active”：true，“type”：“test6”}，{“id”：“456”，“testname”：“test564”，“name”：“Ship Therasus”，“active”：true，“type”：“test7”}]；
变量y=[{“id”：“123”，“国家”：“美国”，“州”：“KA”，“年龄”：24，“集团”：“g1”}，{“id”：“456”，“国家”：“英国”，“州”：“MA”，“年龄”：28，“集团”：“G2”}]；
对于（x中的i）{
对于（j in y）{
如果（x[i].id==y[j].id）{
结果.push（$.extend（x[i]，y[j]）；
}
}
}  
控制台日志（结果）；
});

<script>
$(document).ready(function(){
var result=[];
    var x=[{"id": "123","testname": "test123", "name": "John Doe","active": true,"type": "test6"},{"id": "456", "testname": "test564", "name": "Ship Therasus", "active": true,"type": "test7" }];
var y = [{ "id": "123", "country": "USA", "state": "KA", "age": 24,"group": "g1"},{ "id": "456", "country": "UK", "state": "MA", "age": 28, "group": "G2"}];
for (i in x){
    for (j in y){
      if(x[i].id == y[j].id){

          result.push($.extend(x[i], y[j]));

          }
       }
   }  
console.log(result);

});
</script>
