add array object into object

Question

var objectz = {};
objectz.a = 1;
objectz.b = 2

objArr = JSON.parse(localStorage.getItem('myItem'));

$.each(objArr, function(key,obj){
objectz.key = obj;
}

console.log(objectz);

I want to add array value into my existing obj, I got {1,2,10} where 3 to 9 is got override, where is my mistake?

Answer 1

Aside from syntax errors (copy/paste error?), your code is iterating through objArr and overwriting a property literally called "key" on objectz (ie objectz.key ). You are not using the function parameter iterator called key . If you wanted to use the function parameter called key to update objectz then you probably want to use objectz[key] .

It is hard to guess what localStorage.getItem('myItem') returns. Assuming objArr = [{c: 3},{d: 4},{e: 5},{f: 6},{g: 7},{h: 8},{i: 9},{j: 10}] , here is a corrected version of your code:

http://jsbin.com/viwiko/edit?js,console

var objectz = {};
objectz.a = 1;
objectz.b = 2;

objArr = [{c: 3},{d: 4},{e: 5},{f: 6},{g: 7},{h: 8},{i: 9},{j: 10}];
//JSON.parse(localStorage.getItem('myItem'));

//$.each(objArr, function(key,obj){
//  objectz.key = obj;//overwrites a property called 'key' for each element of objArr
//});

$.each(objArr, function(key,obj){
  objectz[key] = obj;//key will be the zero based array index (i.e. 0 to 7 for the example data)
});

console.log(objectz);

Answer 2

var objx = {};
objx.a = 1;
objx.b = 2

var objArr = JSON.parse(localStorage.getItem('myItem'));

$.each(objArr, function(key,obj){
objx[key] = obj;
}

console.log(objx);

object is a reserve word i believe if i am not mistaken
