How to highlight the selected day [solution]

[HarrySiereveld]

FYI:

action: function () {
$(".day").removeAttr("style"); // to remove style on all previous selected days
$("#" + this.id+"_day").css("background-color", "#ffff00"); // to add style on selected day
var date = $("#" + this.id).data("date"); // if needed to get date-specific data
},
