bootstrap-datetimepicker源码解读

1.插件的使用

    单独输入框

<input class="date_input form-control">$(".date_input").datetimepicker({language:  'zh-CN',autoclose: 1,minView: 2,maxView: 2,format:"dd"
});

    输入框加图标

<div class="input-group date trigger_date_input form-group"><input type="text" class="form-control risk-form-control-regular" id="triggerDate" data-bv-notempty-message="请输入触发时间！" readonly><span class="input-group-addon trigger-date-icon"><i class="glyphicon glyphicon-calendar"></i></span>
</div>$(".trigger_date_input").datetimepicker({language:  'zh-CN',autoclose: 1,minView: 2,maxView: 2,format:"dd"
});

   时间段

var startDate=$('#startTime').val()?$('#startTime').val():new Date();$('#startTime').datetimepicker({language: "zh-CN",format: "yyyy-mm-dd hh:ii",autoclose: true,todayBtn: true,minuteStep: 10,startDate:startDate}).on("click",function(){var endTime=$("#endTime").val();if ( endTime ){$("#startTime").datetimepicker("setEndDate",endTime);};});$('#endTime').datetimepicker({language: "zh-CN",format: "yyyy-mm-dd hh:ii",autoclose: true,todayBtn: true,minuteStep: 10}).on("click",function(){var startTime=$("#startTime").val();if ( startTime ){$("#endTime").datetimepicker("setStartDate",startTime);};});

    事件接口：show、hide、outOfRange（点击不可选的日期触发）、prev/next（左右箭头点击触发）、changeMonth、changeYear、changeMinute、changeHour、changeDay、changeDate、changeMode（时间选择器面板状态改变时触发）

2.插件的结构

Datetimepicker($ele,options)构造函数梳理配置项和执行初始化方法，prototype属性中写入方法、触发事件；

$.fn.datetimepicker构造插件时使用$this.data("datetimepicker",new Datetimepicker)执行初始化操作；

$.fn.datetimepicker.Constructor=Datetimepicker提供Datetimepicker构造函数的接口；

$.fn.datetimepicker.noConflict调用完成以后执行释放$.fn.datetimepicker。

Datetimepicker方法show、fill、update、setValue的拆分需要再领会。。。

3.新启示

$.map方法将数组作为jquery对象处理，执行遍历操作；

Date对象API操作；

var args = Array.apply(null, arguments);将arguments转化成真实数组输出；

Math.min方法促使某值自加1的时候不至于超过限定值，Math.max设置最小为0；

绑定事件通过通过数组、$.on({click:$.proxy(fn,object),keyup:$.proxy(fn,object)})的形式达成；

$.proxy(fn,object)首先将函数fn赋给DOM元素的事件，其次将该函数的上下文改变成object；

$.trigger({type:"show",date:this.date})方法传入触发事件类型以及相应的参数，提供事件接口。

parseDate通过format设定的时间格式将2014-07-11形式或者2014-January-11，12:00am的date转化成utc格式的时间;* （$([1,2,3])将[1,2,3]作为jquery对象处理，可以使用filter方法，this指代当前的数组元素）* formatDate将utc格式的时间输出为format格式的时间数据;*
