jQWidgets jqxScheduler contextMenuOpen 属性

jQWidgets是一个 JavaScript 框架，用于为 PC 和移动设备制作基于 Web 的应用程序。它是一个非常强大、经过优化、独立于平台且得到广泛支持的框架。 jqxScheduler小部件用于在一天、一周、一个月、时间线日、时间线周以及时间线月视图中显示一组约会。

每当从显示的 jqxScheduler 打开上下文菜单时， contextMenuOpen 属性用于设置或返回调用的函数。它是函数类型，默认值为 null。

句法：

设置 contextMenuOpen 属性。

$("#Selector").jqxScheduler({ 
    contextMenuOpen: function (list, appointment, event) {
        $('#log').text("Context menu is opened!");
    },
});

返回 contextMenuOpen 属性。

var contextMenuOpen = 
    $('#Selector').jqxScheduler('contextMenuOpen');
