jquery ajax: newbie question

1. A file called test contai开发者_如何转开发ning the following line:

   [{"foo":"abc","bar":"01"},{"foo":"def","bar":"02"}]

2. jquery ajax:

   $.ajax({ url: "test", success: function(data) {....

Stupid question maybe, but shouldnt i be able to get the values in the function with something like data.foo ? Never used ajax before as you might have figured out :)

In your specific case, you can't exactly call data.foo because your data object is actually an array of objects, so you would access its properties with data[0].foo, data[1].foo and so on.

Yes, you would be able, the [{"foo":"abc","bar":"01"},{"foo":"def","bar":"02"}] data structure is called json and jQuery parses it without problem, it even has a specific method for json jQuery.getJSON. See examples here:
