Got a simple JSON question - here's the code that I'm using to setup a JSON dataset:

Code:
            var inputs = $('#addnewbuyer').contents().find('input');
            var postArray = new Array();
            var postJson = {};
            $.each(inputs, function(i,input){
                var inputId = $(input).attr('id');
                var inputVal = $(input).val();
                postJson = { inputId : inputVal };
            });
I'm using jQuery to assist with this.

Here's the problem. In the line where I set postJson I want the inputId to change based on the ID of the element I am using.

Is there an easier way to do this (or a way in which it will actually work)?
