AJAX Request that fetches ID as well and puts that into the HTML

I'm trying to make an Ajax search form - This form will simply search the database for names.

The table design is as follows:

id   name         开发者_JAVA技巧age
1    some name    10
2    some name2   11
3    some name3   12

Each name is associated with a unique ID.

I want to create a drop down menu of top hits when the user enters their search string.

Also, somehow in the background i would like to retrieve the associated ID with each result as well. That ID will be POST'ed to a form say

 myform.php

Now, my question is as follows:

1) How do i create the drop down menu? I believe i can follow this tutorial and simply customise it to create a drop down menu. http://www.w3schools.com/ajax/ajax_aspphp.asp This would be fairly simple.

2) The main question is, how do i keep track of the ID and selected name, so that i can POST that ID to myform.php

Thanks.
