How to get an object value, which property is equal to a variable value

Question

Please help me to solve the task below.

I want to display an object value, which property is equal to the variable txt. If txt = "my location", I want to display the value of “my location”.

And also I want to display it in such way:

city: value1,

street: value2

var obj = {“my name”: “first second”, “my location”: {“city”: “value1”, “street”: “value2”}};
objkeys = Object.keys(obj);
for (var i = 0; i < objkeys.length; ++i) console.log(objkeys[i]);
var txt = “my location”;
if (txt === objkeys[i]) console.log(???)

What should be written instesd of ???

Thanks!

The last line is not using the for loop; you should add { ... } — Jeroen Heier, Dec 15 '17 at 05:00

var obj = {"my name": "first second", "my location": {"city": "value1", "street": "value2"}};
var txt = "my location"

console.log(obj[txt])
// {"city": "value1", "street": "value2"}

What does this code do? Does it solve the problem? If yes, how? If not, why? – Rajesh Dec 15 '17 at 05:05

var obj = {"my name": "first second", "my location": {"city": "value1", "street": "value2"}};
var text="my location"
for (var key in obj[text]){
    console.log(key+':'+obj[text][key])
}

use obj[text] to get the value of "my location" in obj, here you will get an object. Then for each key of this obj, you can get the 'key' directly and use that key to get the value of each key in "my location" by obj[text][key]
