Jquery change select option depending on anchor change

I have this piece of code for select option:

<select class="select-box" name="select-choice-month" id="select-locations">
  <option id="1">Select Region</option>
  <option id="2" value="eu">Europe</option>
  <option id="3" value="nam">North America</option>
  <option id="4" value="sam">Latin America</option>
  <option id="5" value="aspa">Asia/Pacific</option>
</select>

On select change I already have to change its background like this (displaying or hiding specific div):

$('#select-locations').change(function() {
    $('#form1, #form2, #form3, #form4, #form5').hide();
    $('#form' + $(this).find('option:selected').attr('id')).show();
});

But, now I have mini navigation which is also displaying or hiding same div's

<div id="map-menu">
    <a href="#" id="3">North America</a>
    <a href="#" id="4">Latin America</a>
    <a href="#" id="5">Asia/Pacific</a>
</div><!-- end of map-menu -->

Jquery for this:

$('#map-menu a').click(function() {
    $('#form1, #form2, #form3, #form4, #form5').hide();
    $('#form' + $(this).attr('id')).show();
});

How can I achieve when anchor is clicked and div is changed to change output (name) of selected option also? In first example that is working, but when I am changing it through anchors it doesnt work ...

Tnx for any answers

If I read your question correctly then I think the following should solve your problem and reduce code repetition.

$('#map-menu a').click(function() {
    $('#select-locations').val(this.id).change();
});

It will listen for a click on the as and then set the value of the select list to the clicked id. Once this is complete it will trigger the change event on the select list causing your change listener to be triggered.

Also a note on your ids they should not just be a number:

ID and NAME tokens must begin with a letter ([A-Za-z]) and may be followed by any number of letters, digits ([0-9]), hyphens ("-"), underscores ("_"), colons (":"), and periods (".").

Updated work around from comments

If you want to use your current HTML then it would be something like this:

$('#map-menu a').click(function() {
    var select = $('#select-locations');
    var option_to_select = $('option[id="' + this.id + '"]', select);
    select.val(option_to_select.val()).change();
});

But it should be noted that your code currently does not have unique ids so I suggest you namespace them like:

select_option_1
anchor_option_1

Then the above code would become:

$('#map-menu a').click(function() {
    var option_id = this.id.replace('anchor', 'select');
    var select = $('#select-locations');
    var option_to_select = $('option[id="' + option_id + '"]', select);
    select.val(option_to_select.val()).change();
});

And here it is as a jsFiddle you can run: http://jsfiddle.net/6tHnj/
