Get value from select box

[PF2G]

Hi,

how can i know (with an alert) the value i selected, from the #layout_select:

    <script>
                $(document).ready(function() {
                    var optarray = $("#layout_select").children('option').map(function() {
                        return {
                            "value": this.value,
                            "option": "<option value='" + this.value + "'>" + this.text + "</option>"
                        }
                    })

                    $("#column_select").change(function() {
                        $("#layout_select").children('option').remove();
                        var addoptarr = [];
                        for (i = 0; i < optarray.length; i++) {
                            if (optarray[i].value.indexOf($(this).val()) > -1) {
                                addoptarr.push(optarray[i].option);
                            }
                        }
                        $("#layout_select").html(addoptarr.join(''));
                    }).change();
                });
            </script>


            <select name="column_select" id="column_select">
                    <option value="col1">Com partida em</option>

$("#layout_select").val() should contain the selected value.

Sorry, i wasn't clear enough... I want to refresh the <p> text everytime i change the #layout_select

<script>
            $(document).ready(function() {
                var optarray = $("#layout_select").children('option').map(function() {
                    return {
                        "value": this.value,
                        "option": "<option value='" + this.value + "'>" + this.text + "</option>"
                    }
                })

                $("#column_select").change(function() {
                    $("#layout_select").children('option').remove();
                    var addoptarr = [];
                    for (i = 0; i < optarray.length; i++) {
                        if (optarray[i].value.indexOf($(this).val()) > -1) {
                            addoptarr.push(optarray[i].option);
                        }
                    }
                    $("#layout_select").html(addoptarr.join(''));
                }).change();


                var myString = $("#layout_select").val();
                var myArray = myString.split('_');

                $("p#val").text(myArray[1]);
            });
        </script>

        <p id="val"></p>
