My function:

$('#txtFecha').focusout(function () {

        var fecha = document.getElementById('txtFecha').value;
        var edad = '';

        //supose my date is dd/mm/yyyy
        if ((fecha.substring(2,3) != "/") && (fecha.substring(5,6) != "/")) {
            edad = '';
        }
        else {
            var dia = fecha.substring(0, 2);
            var mes = fecha.substring(3, 5);
            var anio = fecha.substring(6, 10);
            var diaActual = (new Date).getDay();
            var mesActual = (new Date).getMonth();
            var anioActual = (new Date).getFullYear();

            if (mes > mesActual)
                edad = anioActual - anio - 1;

            if (mesActual == mes && dia > diaActual)
                edad = anioActual - anio - 1;

            edad = anioActual - anio;

            if (edad < 0 || edad > 100)
                edad = '';

        }
        $("#txt2Edad").val(edad);

    });

--markup--
<input id = "eAge" type = "text"/>
<input type=  "button" id = "fAge"  value = "find"/>
<input id = "age" type = "text"/>

--jQuery --

$("#fAge").click(function() {
    var currentYear = (new Date).getFullYear();
    var year = $("#eAge").val().split(',');
    $("#age").val(currentYear - year[1]);
});

here's the jsFiddle link to it -- http://jsfiddle.net/GGgqx/

Kris,

I had a similar issue and used this page as a ref a while ago:

or this:

just wrap your call inside the required jquery button click etc.

cheers
