daterangepicker时间范围选择插件

最近前端需要根据一定时间区间选择数据库里面的数据。我们使用bootstrap的

daterangepicker,只要添加daterangepicker.js、daterangepicker.css以及moment.js，bootstrap插件即可。这个控件可以实现如下图的效果。

在使用这个控件前需要设置相应的参数。

                        dateLimit:{

                           months:3

                        },

                        timePicker: true, //显示时间

                        timePicker24Hour: true, //时间制

                        showDropdowns:true,//显示下拉月份选择

                        defaultDate: new Date(),

                        drops:'down',

                        opens:'right',

                        startDate: '1989-01-01',//起始时间

                        endDate: '3013-12-31',//结束时间

                        autoUpdateInput: false,

                        locale:locale,//本地化设置。

                        ranges:{}

但是这个控件左边的月份、年份改变后，右边也是随着改变，间隔是一个月份。目前没有研究到底需要设置哪个参数，可以将时间跨度不是一个月的间隔。来看一下这个插件左右日期改变函数写法。

monthOrYearChanged: function(e) {
            var isLeft = $(e.target).closest('.drp-calendar').hasClass('left'),
                leftOrRight = isLeft ? 'left' : 'right',
                cal = this.container.find('.drp-calendar.'+leftOrRight);

            // Month must be Number for new moment versions
            var month = parseInt(cal.find('.monthselect').val(), 10);
            var year = cal.find('.yearselect').val();

            if (!isLeft) {
                if (year < this.startDate.year() || (year == this.startDate.year() && month < this.startDate.month())) {
                    month = this.startDate.month();
                    year = this.startDate.year();
                }
            }

            if (this.minDate) {
                if (year < this.minDate.year() || (year == this.minDate.year() && month < this.minDate.month())) {
                    month = this.minDate.month();
                    year = this.minDate.year();
                }
            }

            if (this.maxDate) {
                if (year > this.maxDate.year() || (year == this.maxDate.year() && month > this.maxDate.month())) {
                    month = this.maxDate.month();
                    year = this.maxDate.year();
                }
            }

            if (isLeft) {
                this.leftCalendar.month.month(month).year(year);
                if (this.linkedCalendars)
                    this.rightCalendar.month = this.leftCalendar.month.clone().add(1, 'month');
            } else {
                this.rightCalendar.month.month(month).year(year);
                if (this.linkedCalendars)
                    this.leftCalendar.month = this.rightCalendar.month.clone().subtract(1, 'month');
            }
            this.updateCalendars();
        },

至于上面的实现代码，网络上资料很多，这里也贴出来，说不定忘记了还可以回忆一下。

 var locale = {
            "format": 'YYYY-MM-DD HH:mm:ss',
            "separator": " -222 ",
            "applyLabel": "确定",
            "cancelLabel": "取消",
            "fromLabel": "起始时间",
            "toLabel": "结束时间'", 
            "customRangeLabel":"自定义",
            "weekLabel": "W",
            "daysOfWeek": ["日", "一", "二", "三", "四", "五", "六"],
            "monthNames": ["一月", "二月", "三月", "四月", "五月", "六月", "七月", "八月", "九月", "十月", "十一月", "十二月"],
            "firstDay": 1
    };

    getUserDefineDateTime();
    function getUserDefineDateTime(){
                  $('input[name="datefilter"]').daterangepicker({  
                        dateLimit:{
                           months:3
                        }, 
                        timePicker: true, //显示时间
                        timePicker24Hour: true, //时间制
                        showDropdowns:true,
                        defaultDate: new Date(),
                        drops:'down',
                        opens:'right',
                        startDate: '1989-01-01',
                        endDate: '3013-12-31',
                        autoUpdateInput: false,
                        locale:locale,
                        ranges:{}
                   });

                  $('input[name="datefilter"]').on('apply.daterangepicker', function(ev, picker) {
                      $(this).val(picker.startDate.format('MM/DD/YYYY') + ' - ' + picker.endDate.format('MM/DD/YYYY'));
                   });

                  $('input[name="datefilter"]').on('cancel.daterangepicker', function(ev, picker) {
                     $(this).val('');
                  });
    }
