Easyui时间选择框重构

　　【只能选择年和月且下拉框只显示月份】　

<input id="attYearMonth" class="easyui-datebox" data-options="editable:false">

//初始化时间下拉框
function getTimePicker() {
    $('#attYearMonth').datebox({
        //显示日趋选择对象后再触发弹出月份层的事件，初始化时没有生成月份层
        onShowPanel: function () {
            //触发click事件弹出月份层
            span.trigger('click');
            if (!tds)
                //延时触发获取月份对象，因为上面的事件触发和对象生成有时间间隔
                setTimeout(function () {
                    tds = p.find('div.calendar-menu-month-inner td');
                    tds.click(function (e) {
                        //禁止冒泡执行easyui给月份绑定的事件
                        e.stopPropagation();
                        //得到年份
                        var year = /d{4}/.exec(span.html())[0],
                            //月份
                            //之前是这样的month = parseInt($(this).attr('abbr'), 10) + 1; 
                            month = parseInt($(this).attr('abbr'), 10);

                        //隐藏日期对象                     
                        $('#attYearMonth').datebox('hidePanel')
                            //设置日期的值
                            .datebox('setValue', year + '-' + month);
                    });
                }, 0);
        },
        //配置parser，返回选择的日期
        parser: function (s) {
            if (!s) return new Date();
            var period = $("#TimeID").combobox("getValue").toString();
            if (period != "Year") {
                var arr = s.split('-');
                return new Date(parseInt(arr[0], 10), parseInt(arr[1], 10) - 1, 1);
            } else {
                return new Date(parseInt(s, 10), 1, 1);
            }
        },
        //配置formatter，只返回年月 之前是这样的d.getFullYear() + '-' +(d.getMonth()); 
        formatter: function (d) {
            var period = $("#TimeID").combobox("getValue").toString();
            if (period != "Year") {
                var currentMonth = (d.getMonth() + 1);
                var currentMonthStr = currentMonth < 10 ? ('0' + currentMonth) : (currentMonth + '');
                return d.getFullYear() + '-' + currentMonthStr;
            } else {
                return d.getFullYear();
            }
        }
    });

    //日期选择对象
    var p = $('#attYearMonth').datebox('panel'),
        //日期选择对象中月份
        tds = false,
        //显示月份层的触发控件
        span = p.find('span.calendar-text');
    var curr_time = new Date();

    //设置前当月
    $("#attYearMonth").datebox("setValue", myformatter(curr_time));
}
//更改时间格式
function myformatter(date) {
    //获取年份
    var y = date.getFullYear();

    var period = $("#TimeID").combobox("getValue").toString();
    if (period != "Year") {
        //获取月份
        var m = date.getMonth();
        if (m == 1) {
            return y + '-' + (m + 1);
        }
        return y + '-' + m;
    } else {
        return y;
    }
}

　　【用周期下拉框来控制时间选择框的显示值】

function changeDate() {
    var period = $("#TimeID").combobox("getValue").toString();
    var time = $("#attYearMonth").datebox('getValue');
    var date = new Date();
    var y = date.getFullYear();
    var m = date.getMonth();
    var curr = "";
    if (m == 0) {
        y = date.getFullYear() - 1;
        curr = y + "-12";
    } else {
        curr = y + '-' + (m < 10 ? ('0' + m) : m);
    }
    if (time.indexOf('-') > 0 && period == "Year") {
        $("#attYearMonth").datebox('setValue', y);
    }
    if (time.indexOf('-') < 0 && period != "Year") {
        $("#attYearMonth").datebox('setValue', curr);
    }
}

　　【自定义年选择控件（只能选择年）】

function initTimeOptions() {
    var temp = [{ TimeName: '2014', TimeCode: '2014' }, { TimeName: '2015', TimeCode: '2015' }, { TimeName: '2016', TimeCode: '2016' },
    { TimeName: '2017', TimeCode: '2017' }, { TimeName: '2018', TimeCode: '2018' }, { TimeName: '2019', TimeCode: '2019' },
    { TimeName: '2020', TimeCode: '2020' }, { TimeName: '2021', TimeCode: '2021' }, { TimeName: '2022', TimeCode: '2022' },
    { TimeName: '2023', TimeCode: '2023' }, { TimeName: '2024', TimeCode: '2024' }, { TimeName: '2025', TimeCode: '2025' }];
    //var list = JSON.stringify(data);

    $("#attYearMonth").combobox({
        data: temp,
        editable: false,
        valueField: 'TimeCode',
        textField: 'TimeName',
        onSelect: function (data) {
            TimeCode = data.TimeCode;
            TimeName = data.TimeName;
        }
    });
    var date = new Date();
    var year;
　　//一月默认选择上一年
    if (date.getMonth() + 1 == 1) {
        year = date.getFullYear() - 1;
    } else {
        year = date.getFullYear();
    }
    $("#attYearMonth").combobox("setValue", year);
}
