Retrieve values from an array containing objects using JavaScript

As I am exploring Firebug, I encountered an issue where the console log of an array shows: Array [ ] Even though in the right panel of Firebug it is visible that the array contains 3 objects, I am unable to access them. Is there a way to retrieve these values? Here is an image for reference:

Answer №1

There are various JavaScript methods you can use to access items in an array:

var array = ['foo', 'bar', 'hello', 'world'];

// Using a simple for loop
for(var i in array){
    console.log('Value of array item: ', array[i]);
}

// Using forEach loop
array.forEach(function(value){
    console.log('Value of array item: ', value);
});

An array can contain strings, numbers, objects, booleans, etc as its items. Once you have accessed an item using one of the above methods, you can manipulate it according to your needs.

Here is more information on using forEach loops

You can also find information on using traditional for loops here
