Is there a way to style jquery's datepicker days?

Question

Let\'s say I want 5/2/2011 (or any other day) to be a different color than the rest of the days. Is this possible?

This is an example item for a particular day

You can do this by adding a beforeShowDay callback

Bind your callback:

$("input:text.date").datepicker({
    beforeShowDay: SetDayStyle
});

Create your function with some static array of bad dates or construct this array somewhere else:

var badDates = new Array("5/2/2011");
function SetDayStyle(date) {
    var enabled = true;
    var cssClass = "";

    var day = date.getDate();
    var month = date.getMonth() + 1; //0 - 11
    var year = date.getFullYear();
    var compare = month + "/" + day + "/" + year;

    var toolTip = badDates.indexOf(compare) + " " + compare

    if (badDates.indexOf(compare) >= 0) cssClass = "bad";

    return new Array(enabled, cssClass, toolTip);
}

Create your styles

.bad { background: red; }
.bad a.ui-state-active { background: red; color: white; }

The function takes a date as a parameter and must return an array with [0] equal to true/false indicating whether or not this date is selectable, [1] equal to a CSS class name(s) or '' for the default presentation, and [2] an optional popup tooltip for this date. It is called for each day in the datepicker before it is displayed.
