Replace object value with other object's value of the same key with JavaScript

rated 0 times [ 135] [ 3] / answers: 1 / hits: 73688 / 9 Years ago, fri, october 9, 2015, 12:00:00

I've got two objects, item and results.
They've both got the same keys but possibly different values, for example:

item.id = '50'

item.area = 'Mexico'

item.gender = null

item.birthdate = null



results.id = '50'

results.area = null

results.gender = 'Male' 

results.birthdate = null

What I want to do is exactly the following:

if (item.id == null || items.id == 0)

{

    item.id = results.id;

}

but I'm looking for a way to do this for each value of my item object. You know, without having to write a huge function if my objects happen to have a lot more keys / values.
Any ideas?

Update : I misunderstood my own problem and the only issue was that I didnt really understand how to get an object value given a certain key. I couldnt really use any outside scripts or divs since Im using Azure's mobile service scripts.

for (var key in item) {

    if(item[key] == null || item[key] == 0){

        item[key] = results[0][key] 

    }             

}

It could do the trick !

var item = {};

var results={};



item.id = '50'

item.area = 'Mexico'

item.gender = null

item.birthdate = null



results.id = '50'

results.area = null

results.gender = 'Male'

results.birthdate = null



Object.keys(item).forEach(function(key) {

  if (item[key] == null || item[key] == 0) {

    item[key] = results[key];

  }

})

document.getElementById('dbg').innerHTML ='<pre>' + JSON.stringify(item , null , ' ') + '</pre>';



console.dir(item);

<div id='dbg'></div>
