Update multidimensional array by id?

I have a multi dimensional array like this:

var firstElement = $(this).first();
fielddata = {
  number: index,
  attributes: [
    { 'label_text': firstElement.text(), 
      'label_width': firstElement.width(), 
      'label_height': firstElement.height(), 
      'label_color': firstElement.css('color') 
    }
  ]
}

How can I change one of the values inside the attributes part but by id? so I make 'label_text' a different value?

I do not want to use the index.

You don't have a multidimensional array. You have an object; one of its properties is an array of objects.

In this case, it looks like you want to update label_text in the first (and only) object in the attributes list. If that's correct:

fielddata.attributes[0].label_text = 'whatever';

Will work, as would:

fielddata.attributes[0]['label_text'] = 'whatever';
