Interpret a javascript concatenated string as variable

Question

I get data via ajax. In results data.items I have:

image1, image2, ..., imageN

each represents an image name like 109298109991.jpg

I try to write a function

$.each(images, function(i,item){

  var image_n = 'data.items.image' + (i+1); 

  console.log(image_n.value);

  images_restruct.push({ 
  href: '/images/flowercatalog/'+ image_n
  title: 'Image' + i
 });
});

But image_n is interpreted as string data.items.image1, data.items.image2 ... data.items.imageN, not as 01010101001.jpg ... 00001112121.jpg

'data.items.image' : This makes it a string and not the actual image.Remove the quotes — The Dark Knight, Aug 15 '13 at 08:57

Thanks, var image_n = data.items['image' + (i+1)]; Work as expected. — Alexandru Para, Aug 15 '13 at 09:03
