Access object property values in an array of objects javascript

Question

I have an array containing objects that looks like this:

var persArr = [
 {name: "Adam", age: 37}, 
 {name: "Ben", age: 36}, 
 {name: "Chris", age: 46}
 ];

What I would like to do is create a string variable which takes the given names in each object in the array and puts them together like this:

var str = "Adam, Ben, Chris";

Any suggestions as to achieve this?

Answer 1

You can use map and join:

var str = persArr.map(function (pers) {
 return pers.name;
}).join(", ");

Answer 2

Try with:

var names = [];
for (var k in persArr) {
 names.push(persArr[k].name);
}
var str = names.join(', ');

Answer 3

try something like this

 var persArr = [{name: "Adam", age: 37}, {name: "Ben", age: 36}, {name: "Chris", age: 46}];
 var ar_length = persArr.length;
 var temp_arr = [];
 for(var i= 0;i<ar_length;i++){
 temp_arr.push(persArr[i].name);
 }
 alert(temp_arr.join(','));
