在Java脚本中合并两个json对象？

Question

Have u merged two jsons in javascript ??

Problem:

a={id:123,name:john,status:success};
b={id:123,status:inprocess,transId:245};

Output json should be like

{id:123,name:john,status:success,transId:245};

All the values from a should override the ones in b and also the uncommon key/values should appear in output json.

I tried out some recursive options but cudnt acheive the output.

Answer 1

your a and b variable are not valid json.

<script>
//change your a and b variable to this.
 a={id:123,name:'john',status:'success'}; 
 b={id:123,status:'inprocess',transId:245};
$(document).ready(function(){

  $.extend(a,b);

});
</script>

and a will have structure like

{
    id: 123
    name: "john"
    status: "inprocess"
    transId: 245

}

I've used jquery api

update.

without jquery

   a={id:123,name:'john',status:'success'}; 
   b={id:123,status:'inprocess',transId:245};

  extend(a,b);

where extend function is:

 function extend(a, b){
    for(var key in b)
        if(b.hasOwnProperty(key))
            a[key] = b[key];
    return a;
 }

ref1 , ref2 , ref3

Answer 2

It's simple

for (var p in a)
   b[p] = a[p];

Answer 3

let x = {
  a: 1,
  b: 2,
  c: 3  
}

let y = {
  c: 4, 
  d: 5,
  e: 6
}

let z = Object.assign(x, y)

console.log(z)

z:
{
  a:1,
  b:2,
  c:4, 
  d:5,
  e:6,
}

---> NOTICE : the object z take the y's c attribute
