How to get result from select option?

I want to make a select option , where for each option display a different html text on div.

<form>
    <label>Select Country:</label>
    <select class="country">
        <option value="1">United States</option>
        <option value="2">India</option>
        <option value="3">United Kingdom</option>
    </select>
</form>

and jquery .

$("select.country").change(function(){
    var selectedCountry = $(".country option:selected").val();
   // alert("You have selected the country - " + selectedCountry);
    $('#mydiv').prepend('<h2> option one </h2>');
});

How can i achieve this . any idea.
