For example, in the "From" and "To" dropdown list:
http://www.bestplaces.net/col/col.aspx

before the "State" is selected, the "city" is disabled;
after the "State" is sected, the "city" is loaded.

Is there any general way to do these without considering languages (asp, jsp, php...)? or What are the key techniques to achieve this feature?

You can use any kind of scripting language for this.
If you are using server side scripting, Once both the selects are filled, you can submit the form by using onchange=""..
When the form is submitted, on server side find the cities and display them in the remaining selects..

If you see the city drop down menu are empty(view source.)

I guess they are using database to store city information

You can also do that using client side scripting but you have to load all the state and city informationc in javascritp/VBscript array,.
