ReferenceError:事件未定义

本文关键字：未定义 事件 ReferenceError | 更新日期: 2023-09-27 18:04:22

在我的asp.net mvc3页面中，我使用jquery来显示一个日历来显示数据库中添加的事件。它在google chrome中工作正常，但在firefox 19.0.2中显示如下错误

                alert(s);
                showevents(s);

ReferenceError:事件未定义

您可能在showevents功能开始时遗漏了var event;。看到评论:

beforeShowDay: function (date) {
    var result = [true, '', null];
    var matching = $.grep(events, function (event) {
        return event.Date.valueOf() === date.valueOf();
    });
    if (matching.length) {
        // event is not defined
        result = [true, 'highlight', event.Title];
    }
    return result;
},
onSelect: function (dateText) {
    var date, selectedDate = new Date(dateText), i = 0, event = null;
    while (i < events.length && !event) {
        date = events[i].Date;
        if (selectedDate.valueOf() === date.valueOf()) {
            // event is not defined
            event = events[i];
        }
        i++;
    }
    if (event) {
        //return [true, "Highlighted", event.Title];
        // event is not defined
        alert(event.Title);
    }
}
