Answer 1

Be careful. If the json to the variable "result" is in your second code block, you can't expect to find any data by using "result.resort0" or "result.resort1". In your example, result contains a submember called "Resorts" which holds an array of submembers.

In other words, to cycle through all values, I would expect javascript like:

for(var i=0; i<result.Resorts.length; i++) {
  alert(result.Resorts[i].name);
  alert(result.Resorts[i].room1);
  alert(result.Resorts[i].room2);
}
