bootstrap datetimepicker实现秒钟选择下拉框

//添加datetimepicker下拉框，如果配置要选择秒，否则不添加
 
 var addSec = /,s{1,2},/.test(',' + this.format.parts.join(',') + ','), sSec = addSec ? '<select style="width:100%">' : '';
 this.addSec = addSec;
 if (addSec) {
 var orgSec = this.viewDate.getSeconds();
 for (var _i = 0; _i < 60; _i++) sSec += '<option value="' + _i + '"' + (_i == orgSec ? ' selected' : '') + '>' + (_i < 10 ? '0' : '') + _i + '</option>';
 sSec += '</select>';
 }
 this.picker.find('.datetimepicker-minutes td').html(html.join('') + sSec);

click: function (e) {
 e.stopPropagation();
 e.preventDefault();
///防止选择秒钟选择器日期控件层隐藏
 if (e.target.tagName == 'SELECT' || e.target.tagName == 'OPTION') return;

case 'span':
 if (!target.is('.disabled')) {
 var year = this.viewDate.getUTCFullYear(),
 month = this.viewDate.getUTCMonth(),
 day = this.viewDate.getUTCDate(),
 hours = this.viewDate.getUTCHours(),
 minutes = this.viewDate.getUTCMinutes(),
//修改datetimepicker秒钟获取方式
 seconds = this.addSec ? this.picker.find('select').val() : this.viewDate.getUTCSeconds();

 $('.form_datetime').datetimepicker({
 weekStart: 1,
 todayBtn: 1,
 autoclose: 1,
 todayHighlight: 1,
 startView: 2,
 forceParse: 0,
 showMeridian: 1,
 format: 'yyyy-mm-dd hh:ii:ss'///
 });
