How can I add additional value to variable in jquery

Question

I am trying to add dates to a slider and need to increment the values on click. I currently start with the year - 2

$('#adddates').click(function() {
    var year = 2;
    $("#slider").dateRangeSlider({
        bounds: {
            min: new Date(Today.getFullYear() - ++year, 0, 1),
            max: new Date(Today.getFullYear(), Today.getMonth(), Today.getDate())
        }
    });
});

On click I am only getting an additional year. I need to increase the number of the year variable from 2 on each click. How can this be achieved?

On click you are getting an additional year, meaning one. That is evident when using ++year. So can you clarify what you mean then by saying increase the number of the year variable from 2? Do you mean using year += 2 ? — AGE

He wants to maintain the state of year such that it doesn't get reset, at least that is what it sounds like. — JonH

If you're asking how to maintain the year value declare it outside of your click event:

$( document ).ready(function() {
    var year = 2; // abstracting the year away from the click function
    $('#adddates').click(function() {
        $("#slider").dateRangeSlider({
            bounds: {
                min: new Date(Today.getFullYear() - ++year, 0, 1),
                max: new Date(Today.getFullYear(), Today.getMonth(), Today.getDate())
            }
        });
    });
});

Please note however, if for any reason you do some sort of server side post back this value will be reset.

Wouldn't it make more sense to keep it inside the $(document).ready but outside the $("#adddates').click(function ?
