        $(document).ready(function() {
      $("select[name='dropdown']").change(function() {
         if($(this).val()==2){
             //do what u want here
           }//u can check your desired value here
     });
   });

    I think you want this.

    Try this demo http://jsfiddle.net/JGp9e/

    This will help, have a nice one!

    code

    $('select[name="dropdown"]').change(function(){

    if ($(this).val() == "2"){
        alert("call the do something function on option 2");
     }        
});​

    HTML

    <select name="dropdown" size=1>
    <option value="1">option 1</option>
    <option value="2">option 2</option>
</select>​

    You need to use change function

    $('select[name=dropdown]').change(function() {
    alert($(this).val());
});
