This is a note for me to remember how to validate drop down list in Javascript. Although i have done this sooo many times but i still forget how to validate drop down list in javascript :p So hopefully with the help of this post, i’ll be able to refer if i forget again.

To validate drop down list in Javascript, follow the steps below:-

• First your drop down list must have a unique id. so give a id to your select tag like below:-

  <select id="country" name="country">

• Once you have select tag with an ID, you can write a function using the code below to validate the drop down list:-

  if ( document.getElementById('country').selectedIndex == 0 ) {
          alert ( "Please select your country" );
          return false;
  }
  

Hope i wont forget this piece of code again :p
