In this article we have done some research into the
commonly-used four ways to locally update a web page using four respective
examples. These days, AJAX becomes one (accurately not the "one") of the
most popular and valuable techniques to create web applications with quicker response
and better user experience.
I have written this article only with the aim of summarizing
traditional solutions in achieving a partially updating effect so as to better
grasp the idea of AJAX. And, of course, the three foregoing ways have not become
obsolete at all but own each respective scenario.
