Take the 2-minute tour ×  My task is to populate another select
list based on what is choosen from one select list, querying
populating data from database.  I think it goes something like:
2. On select list onChange method a query like select id,
description from table where child_id=_id_ is executed.   3.
Child select list is populated based on that query. Maybe the
result of query is returned in a controller method?

down vote accepted  I would like to recommend you to use Google,
because simple search will provide you the answer.  This code
sample will show you the way how to do it:
$.getJSON("/getSubCategories?id="+$(this).val(), function(j){
var options = '';  Now the Server side:  @RequestMapping(method
= RequestMethod.GET, value = "/getSubCategories") public String
handleRequest( @RequestParam("id") int id) {) { now build your
json string as optionValue and OptionDisplay. String json =
service.getSubCategories(id);  return json
