Parse JSON in jquery

Question

I'm trying to parse the following json line in jquery:

[{
 "pk": 19,
 "model": "films.movies",
 "fields": {
 "length": "92",
 "name": "Beetle Juice",
 "actor": "Keaton", 
 "img_set": [{
 "pk": 42,
 "model": "films.img",
 "fields": {
 "uploaded": "2010-10-08 21:44:30",
 "f_movie": 19,
 "url_med": "http://www.mondial-infos.fr/wp-content/uploads/2009/10/Beetlejuice.jpg"}
 }]
 }
},{
 "pk": 20,
 "model": "films.movies",
 "fields": {
 "length": "126",
 "name": "Batman",
 "actor": "Keaton", 
 "img_set": [{
 "pk": 43, 
 "model": "films.img",
 "fields": {
 "uploaded": "2010-10-08 21:44:54",
 "f_movie": 20, 
 "url_med": "http://bruehoyt.com/superheroes/DC/batman/bruce/batmankeaton3.jpg"}
 }]
 }
}]

I can't access anything after img_set though. What am I missing? Is this valid json?

I am attempting the following:

$.getJSON('/films/feeds/movie-by-actor/Keaton/',function(data) {
 $.each(data, function(i, movie) {
 alert(movie.fields.name);
 alert(movie.fields.img_set[0].pk);
 });
});

The first alert works. The second does not.

In addition, though I don't know that it matters, this is jquery within a django template.

• zod: are you getting an error? how you are accessing?
• Ian Henry: It's valid JSON. Do you mean you can't access any of the properties in the objects in the img_set array, or you can't access the second element in the main array? Code that demonstrates the problem you're having would help.
• Ed.: edited above with code I'm using to try to access data
• mcgrailm: you need alert(movie[0].fields.img_set[0].pk); because move is an array look at Nick's code see how he has it in his
• Ed.: Figured it out. Thanks, all!

Answer 1

The confusing part is probably the array of a single element, but img_set is still an array. Make sure you're accessing it with an index first, like this:

.img_set[0].pk
//for example:
data[0].fields.img_set[0].pk

Instead of just:

.img_set.pk

You can give it a try here.

• Ed.: First, thanks for the link. That's a handy tool. It's weird though that it works there, but it's not working in my code. Same methodology. . .
