Building efficient websites with AJAX
Listing 1 shows the HTML code for a sortable table based on the free Mochikit  library. Besides the two includes in line 6 that bind Mochikit, the HTML source code is little different from a static table. The table tag needs a unique ID (sortable_table) as in the menu example here. The Mochikit-specific attributes mochi:format="int" and mochi:format= "gdate" in the <th> tags help Mochikit sort numeric and date columns correctly.
The previous example stores the table content in the HTML source code; the following example takes things one step further. The application picks up the table content without reloading the page from the server. Links, buttons, and menu items let the user fill the table with different values. Also, it is possible to display search results without page reloads.
If the lists are longer, it is faster to load just the first 25 entries. The user can then click a link or button to load the next 25. This approach reduces the wait time for the user as well as the server load.
