jquery datetimepicker组件实现只选择年月的时间选择器

将配置项修改为以下：
{
    language: 'zh-CN',
    minView: 3,
    maxView: 4,
    format: 'yyyy-mm',
    datepicker: false,
    startView: 3,
    daysOfWeekDisabled: ['01', '02', '03', '04', '05', '06', '00'],
    onRenderDay: function(date) {
        return false;    
    }
}
