I don't see a count property in your JSON data, and you didn't mention
eval'ing the JSON string (it's just a string until you do something with
it).
Assuming that you have received a string from your server in a variable
"json" containing the above JSON text:
json = eval( '(' + json + ')' );
var models = json.models;
for( var i = 0, n = models.length; i < n; ++i ) {
var model = models[i];
console.debug( model );
}
You can even use $.each if you like:
json = eval( '(' + json + ')' );
$.each( json.models, function( i, model ) {
console.debug( model );
});
