Question

How do you set the “city” value to the same thing as country value when there is no option for a city?

For example, Benin doesn’t have an option to select a city inside of it. At this link http://jsfiddle.net/yPb6N/1/, if you select “Benin”, underneath the dropdown it displays Benin undefined. How do you make it display Benin Benin?

<select id="country-select">
    <option value="us">US</option>
    <option value="germany">Germany</option>
     <option>Ireland</option>
    <option>Benin</option>
    <option>Italy</option>
</select>

<select id="us-select" class="sub-menu hide">
    <option value="austin">Austin</option>
</select>

<select id="germany-select" class="sub-menu hide">
    <option value="berlin">Berlin</option>
</select>
<p></p>
<font size="5"><font color="red"><div class="countryvalue" >Value</div></font></font> <br/>
​


function countrySelectChanged() {
    $('.sub-menu').hide();
    var selectedCountry = $('#country-select').val();
    if (selectedCountry) {
        $('#' + selectedCountry + '-select').show();
    }
}

$(document).ready(function() {

    $('#country-select').change(countrySelectChanged );
     countrySelectChanged();

    $("#country-select").change(function () {
          var str = $('#country-select').val() + " " + $("#" + $("#country-select option:selected").val()  + "-select option:selected").val();
          $("#country-select option:selected").each(function () {
            });
          $(".countryvalue").text(str);
        })
        .change();
    });
​

.hide {
display: none;            
}​

My code is not working

    if (($('#country-select').val() != "us") || ($('#country-select').val() != "germany")) {
    $("#" + $("#country-select option:selected").val() + "-select option:selected").val() == $('#country-select').val();
}

thanks 🙂

This line:

var str = $('#country-select').val() + " " + $("#" + $("#country-select option:selected").val()  + "-select option:selected").val();

Needs to be somthing like:

var country = $('#country-select option:selected').val();
var city = $("#" + country  + "-select option:selected").val() || country;
$(".countryvalue").text(country + " " +city);

This way, if the name of the city doesn’t exist, it will use the name of the country. Also, it doesn’t perform multiple selectors for the same element, which is wasteful.

Here is the updated fiddle.
