Answer 1

Welcome to the marvelous world of AJAX. One of the issues with ajax calls is that different browsers have different implementations of ajax. It's better if you can use a javascript library that abstracts these differences. I'd suggest you to pick up jQuery. You can make ajax calls in jQuery using $.get() , $.post() or $.ajax()

Answer 2

看看jQuery.ajax 。

Answer 3
