I have the following object data:

var js_images = {
"newborn_set01_01.jpg":{"filename":"newborn_set01_01.jpg","title":"First Pic","description":"First description..."},
"newborn_set01_02.jpg":{"filename":"newborn_set01_02.jpg","title":"Second Pic","description":"Second description"},
"newborn_set01_03.jpg":{"filename":"newborn_set01_03.jpg","title":"Third Pic","description":"Third description"}
};

How would I do something as simple as creating an alert to show the description of newborn_set01_03.jpg?

This obviously doesnt work:

alert(js_images.newborn_set01_03.jpg.description);

  • the .jpg part of newborn_set01_03.jpg is probably throwing off the program.... well, actually the "." of the .jpg Commented Dec 4, 2012 at 2:07

In addition to dot notation, you can access object members using bracket notation:

alert(js_images["newborn_set01_03.jpg"].description);
