Unable to concatenate values from Object in JavaScript

Although it may seem trivial, the following code is giving me trouble:

window.temp1.targetInterests

It gives me back:

Object {Famosos: "Famosos", Musica: "Música", Humor: "Humor"}

I attempted to join it:

window.temp1.targetInterests.join('/')

and map it:

window.temp1.targetInterests.map(function(elem){
    return elem.name;
}).join(",");

but unfortunately, I keep receiving 

 Uncaught TypeError: undefined is not a function

Can someone point out where I am going wrong?

Your help is greatly appreciated.

Answer №1

One way to combine the keys is by using the Object.keys method:

var combinedKeys = Object.keys(window.temp1.targetInterests).join(",");

If you need the actual values, you can achieve that by looping through the object:

var combinedValues = [];
for (var prop in window.temp1.targetInterests) {
    combinedValues.push(window.temp1.targetInterests[prop]);
}
combinedValues = combinedValues.join(",");
