jQuery get img source attributes from list and push into array

Question

I have this thumbnail list and would like push the image paths (sources) into an array: tn_array

Answer 1

You can create the array of src attributes more directly using map():

var tn_array = $("#thumbnails img").map(function() {
  return $(this).attr("src");
});

Edit: tn_array is an object here rather than a strict Javascript array but it will act as an array. For example, this is legal code:

for (int i=0; i

You can however call get(), which will make it a strict array:

var tn_array = $("#thumbnails img").map(function() {
  return $(this).attr("src");
}).get();

How do you tell the difference? Call:

alert(obj.constructor.toString());

The first version will be:

function Object() { [native code] }

The second:

function Array() { [native code] }
