Question

This code is working fine if ($(this).val() == \"Spine\") but if ($(this).val() == \"Spine\"||\"Brian\") then the selection menu closes then opens

Answer 1

or use switch case

$("#optionbodyRegion").change(function(){
    switch ($(this).val())
{
   case "Spine": case "Brain": 
    document.getElementById('optioncontrast').options[0]=new Option("Select", "", false, false)
                    document.getElementById('optioncontrast').options[1]=new Option("With", "With", false, false)
                    document.getElementById('optioncontrast').options[2]=new Option("Without", "Without", false, false)
                    document.getElementById('optioncontrast').options[3]=new Option("With and Without", "With and Without", false, false)


                    $("#contrast").slideDown("fast"); //Slide Down Effect
   break;
 case "":
$("#contrast").slideUp("fast");   //Slide Up Effect
break;

  default: 
  break;
}
