title: 3 option select set value from database remove onchange
body: <p>I have 3 select option that load values depending on each other</p>
  
  <p>My first select is <code>Continent</code> it has the value of continent on load second select is <code>Country</code> this select will be loaded on change of continent then last select is <code>City</code> this will be loaded on change of country it works fine</p>
  
  <p>Currently because of the onchange event of the the select statement when i load data in the select from database it is not showing the correct data because the one that it is showing is the data when the on change event.</p>
  
  <p>My question is how do i stop the onchange event of the 3 select option so that i can load data from database i was thinking that stopping the onchange is the best way to load data from database. If there are any other option to load data on these select i will gladly try it.</p>
