I have a array that looks like the following:

I would like to add a new item, named "attributes", which is also an array. I can I do that?

Thanks.

Answer 1

 var test = [{ enabled: true, key: 'FIN28', text: 'Service Agreement' }, { enabled: true, key: 'test', text: 'test test' }]; for (var i = 0; i < test.length; i++) { test[i]['attributes'] = []; } console.log(test); 

Answer 2

According to your comment, you want to add an attribute named "attribute" to the object inside your array. you can do it like this :

myarray[0].attribute = myvalue;

If you want to do it for every item of your array, you can do this :

for(var idx in myarray)
    myarray[idx].attribute = myvalue;
