Callback Options (Pro)

With callback options, you can run function before and after slide transition effect, for example:

var myEvoSlider = $("#mySlider").evoSlider({
    before: function(){
        alert( this.getIndex() );
    },
    after: function(){
        alert( this.getIndex() );
    }
});
                

You can access the Evo Slider API from the inside of the callback function using the this keyword.
