Question

I have 3 select boxes and one input.

I need to merge the selected values together and add it to the hidden input box.

For example:

<select name="select-choice-1" id="select-choice-1">
            <option value="1-">1</option>
</select>

<select name="select-choice-1" id="select-choice-2">
            <option value="5-">5</option>
</select>

<select name="select-choice-1" id="select-choice-3">
            <option value="2011">2011</option>
</select>

Finally I want to get:

Is this case the value would be:

1-5-2011

How could I get this functionality togehter please?

JSFiddle Demo:

one way to do it is:

HTML:

<select name="select-choice-1" id="select-choice-1">
    <option value="1-">1</option>
    <option value="2-">2</option>
    <option value="3-">3</option>
</select>

<select name="select-choice-1" id="select-choice-2">
    <option value="5-">5</option>
    <option value="6-">6</option>
    <option value="7-">7</option>
</select>

<select name="select-choice-1" id="select-choice-3">
    <option value="2011">2011</option>
    <option value="2012">2012</option>
    <option value="2013">2013</option>
</select>
<input type='hidden' id='myhidden' value='' />

JavaScript:

<script type='text/javascript'>
   $(document).ready(function() {
    $('select').each(function() {
        $(this).change(function() {
            var myele = '';
            $.each($('select option:selected'), function() {
                myele += $(this).val();
            });
            $('#myhidden').val(myele);
            console.log($('#myhidden').val());
        });
    });
   }); 
</script>
