http://docs.jquery.com/Selectors/input. And while I don't know what you're going to use it for, http://docs.jquery.com/Ajax/serialize might be of interest as well.

Answer 2

This code will find all input, select and textarea elements and construct an object mapping element names to their values:

var form = $("#someform");
var postData = {};

form.find(':input').each(function()
{
    postData[$(this).attr('name')] = $(this).val();
});
