Answer 1

Here is a rough idea , you need to refine it according to your need

<script type="text/javascript">

            $(function(){

            var sb1_val;
            var sb2_val;

             $('#sb1').on('change', function() 
             {
                sb1_val = this.value ;
             });

             $('#sb2').on('change', function()
             {
                sb2_val = this.value ;

                 console.log(sb1_val+','+sb2_val); //this will output the both
                 alert(sb1_val+','+sb2_val); //this will output the both

             });

            });


        </script>


    <select id='sb1'>
        <option value='car1'>car1</option>
        <option value='car2'>car2</option>

    </select>


    <select id='sb2'>
        <option value="golf1">golf1</option>
        <option value='golf2'>golf2</option>

    </select>

Answer 2

Here is a working demo in pure JavaScript.

The solution I have proposed is to capture the onchange event and display it in a div tag using innerHTML .

HTML:

<select id="select1">
   <option> cars </option>
   <option> bikes </option>
</select>
<div id="output"></div>

JavaScript:

document.getElementById("select1").onchange=function(){
    var e = document.getElementById("select1");
    selected1  = e.options[e.selectedIndex].text;
    if(selected2!="")
       document.getElementById("output").innerHTML = selected1 + ", " + selected2;

};

Answer 3

Simply use the .change() in jQuery.

$("select").change(function(){
    //output the values
    $("#my_output").val($("#s1").val() + "," + $("#s2").val());
});
