ajax - How to implement a Chained menu in PHP? -

-

I have to do an AJAX function to implement a chain menu + a result table.

What do I have to do:

First of all, the page automatically populates a vertical menu from MySQL and results table.

Secondly, when I click on an item in the menu, then it displays a submenu and a new result table in a certain area in the page.

Thirdly, when I click on an item submenu, it displays a sub-submenu in another set area of ​​this page and a new result table.

Last, when I click an item in sub-submenu, it displays a result table.

All the result tables are in the same position. It changes on the basis of clicks in the menu

I believe this is written in Javascript + jQuery, so that you learn from its source Able to

I'm using Oracle 10. # Tips for Hibernation & amp; Tricks It suggests writing in such a way: Integer number = (integer) session .createQuery ("Select Count (*) to ...."). UniqueResult (); I do not know what is the magic of the unique rule? Why does it fast? To compare, select "1 from mytable where parent_id = passId and rowrum", which is more efficient? If you are not interested in the number of records, then there is an EXISTS query one: Select 'y'
