Question

I am trying to create a Array of Array containing objects,

Here is my code,

var objA = new Array();

function myFunction(){
     objA ['1'] = new Array();
     objA ['1'].push({'bird':'parrot','animal':'rabbit'});
     var item = objA ['1'];
     alert(item['bird']);
}

Now ideally above code should alert ‘parrot’, but instead I get ‘undefined’.
What am I doing wrong?

Answer 1

You set the attribute to a new array:

objA ['1'] = new Array();

So, of course, when you retrieve it, you’re getting back an array.

var item = objA ['1'];

Arrays don’t have a bird attribute. The first item in the array does, though.

alert(item[0]['bird']);
