Updating JSON object using another JSON object

Question

I am using AngularJS

How to update the "name" and "gender" in this JSON object:

{ name: "John", gender: "male", status: "single", createdBy: "Andrew" }

With this "name" and "gender" in this JSON object:

{ name: "Anna", gender: "Female"}

The updated JSON object will be this:

{ name: "Anna", gender: "Female", status: "single", createdBy: "Andrew" }

Hoping for an informative response. Thank you!

//try this...
var json1 = { 
    name: "John", 
    gender: "male", 
    status: "single", 
    createdBy: "Andrew" 
};
var json2 = { 
    name: "Anna", 
    gender: "Female"
};
//extending json2 values to json1
angular.extend(json1, json2);

Just assign the new values to the properties,

   jsonObj.name = newObj.name;
   jsonObj.gender = newObj.gender;

DEMO

var jsonObj = { name: "John", gender: "male", status: "single", createdBy: "Andrew" };
var newObj = { name: "Anna", gender: "Female"};
jsonObj.name = newObj.name;
jsonObj.gender = newObj.gender;
console.log(jsonObj);

is there no way to just like merge the two obj? Like making: JsonObj1 = JsonObj2;

Sajeetharan Over a year ago

what do you mean by merge?

Sajeetharan Over a year ago

since you want to assign only specific properties, you cant completely assign the whole object. just assign the properties as mentioned in demo

Because this is an edit function. Some of the values of the old JSON Object are replaced by the values of the new JSON object. I just ran out of idea on how to do it.
