When using jquery ajax with data that contains array, getting the parameter name with [] in the end

Question

$.ajax({
            url:"SomeURL",
            data: {                
                fields : ["field1", "field2"],                
            },
            success: function(data) {
            }
});

Getting this in the server:

name = fields[] , VALUE = field1
name = fields[] , VALUE = field2

(note the brackets)

Is that a bug? (This starting to happen after I upgraded to 1.5)

Thanx

Answer 1

It is not a bug, the serialization changed (but already in jQuery 1.4). Have a look at the traditional option:

traditional Boolean
Set this to true if you wish to use the traditional style of param serialization.

And from jQuery.param() (also have a look at the example):

As of jQuery 1.4, the $.param() method serializes deep objects recursively to accommodate modern scripting languages and frameworks such as PHP and Ruby on Rails. You can disable this functionality globally by setting jQuery.ajaxSettings.traditional = true;.
