更改Lift/Scala中某些CalendarItem的背景

我正在尝试使用Lift和CalendarMonthView小部件来构建一个 预约制。

CalendarMonthView和Lift配合得很好,但我有个问题 无法更改上显示的某些日历项的样式

根据API文档,我使用以下代码来更改

class MySnippet {
    def test (xhtml: NodeSeq) = {
        val c    = Calendar.getInstance
        val meta = MonthViewMeta (Calendar.SUNDAY, Locale.getDefault)

        c.set (2010, 0, 0)

        bind ("cal", xhtml, 
              "widget" -> CalendarMonthView (c, meta, cals, Empty, 
                                             Empty, Empty))
    }

    def cals = {
        val c1 = Calendar.getInstance
        val c2 = Calendar.getInstance

        c1.set (2010, 0, 5, 10, 0)
        c2.set (2010, 0, 6, 10, 0)

        val calitem1 = CalendarItem ("4", c1, CalendarType.MEETING).
                       optional (
                           _.subject     ("Red Item"),
                           _.description ("Background should be read")
                       )

        val calitem2 = CalendarItem ("5", c2, CalendarType.MEETING).
                       optional (
                           _.subject     ("Green Item"),
                           _.description ("Background should be green"),
                           _.baseCSSClassName ("greenItem")
                       )


        List (calitem1, calitem2)
    }

}

我已经确认在输出HTML中,calitem2有一个“cssClass” 属性设置为“greenItem”。

var calendars = {
    "items": [{"id": "4", "start": 20, "end": 48,
               "weekDay": "3", "startTime": "10:0",              
               "subject": "Red Item", "month": 0, "dayOfMonth": 5,              
               "description": "Background should be read"},
              {"id": "5", "start": 20, "end": 48, "weekDay": "4", 
               "startTime": "10:0", "subject": "Green Item", "month": 0, 
               "dayOfMonth": 6, "description": "Background should be green", 
               "cssClass": "greenItem"}]
};             

我还重写了CalendarMonthView附带的原始样式css 把它放在WEB-INF/classes/toserv/calendars/monthview下。

我已经浏览了它,并确保它是我的修改版本,其中添加了 下面的“greenItem”CSS类。

.greenItem {
        margin: 1px;

}

.greenItem a {
        margin-left: 1px;
        color: #FFFFFF;
        text-decoration: none;
        background-color: #00FF00;
        display: block;

}

.greenItem a:hover {
        text-decoration: none;
        background-color: #ff6655;
        display: block;

}

.greenItemHead {
        margin: 1px;

}

.greenItemHead a {
        margin-left: 1px;
        color: #FFFFFF;
        text-decoration: none;
        background-color: #00FF00;
        display: block;

}

.greenItemHead a:hover {
        text-decoration: none;
        background-color: #ff6655;
        display: block;

}

.greenItemBody {
        margin: 1px;

}

.greenItemBody a {
        margin-left: 1px;
        color: #FFFFFF;
        text-decoration: none;
        background-color: #00FF00;
        display: block;

}

.greenItemBody a:hover {
        text-decoration: none;
        background-color: #ff6655;
        display: block;
}

但是当我浏览我的日历页面时,第二个日历项仍然是 在红色背景中,CSS类似乎不起作用。

我不熟悉JavaScript和JQuery,所以我会错过什么吗?
