时间比较使用字符串yymmdd既方便比较又不需要转换
处罚时间: 最大时间不能大于当前时间,这里使用maxDate:‘currentDay‘这是前面引入文件包含的currentDay,currentDay当前时间为服务器时间
,第二个日期大于第一个日期,日期显示值为:yyyy-mm-dd 日期实际值为yyyymmdd (日期为服务器时间)
<input type="text" id="date01" class="tdInput_80" onfocus="WdatePicker({dateFmt:‘yyyy-MM-dd‘,realDateFmt:‘yyyyMMdd‘,vel:‘startDate‘,maxDate:‘#F{$dp.$D(\‘date02\‘)||\‘%y-%M-{%d}\‘}‘,readOnly:true})"/> --
<input type="hidden" id="startDate" name="punish.startDate" />
<input type="text" id="date02" class="tdInput_80" onfocus="WdatePicker({dateFmt:‘yyyy-MM-dd‘,realDateFmt:‘yyyyMMdd‘,vel:‘endDate‘,minDate:‘#F{$dp.$D(\‘date01\‘)}‘, maxDate:‘currentDay‘,readOnly:true})"/>
<input type="hidden" id="endDate" name="punish.endDate" />
sql:这是使用的是xml，其实不用xml也一样，条件判断不为空就加上条件
#if($startDate && !$startDate.equals(""))
and p.peccancy_time>=#[startDate]
#end
#if($endDate && !$endDate.equals(""))
and p.peccancy_time<=#[endDate]
#end
选择的日期不能大于当前日期(日期为服务器时间) maxDate:‘currentDay‘
<input type="text" id="checkdate_add" class="tdInput" onfocus="WdatePicker({dateFmt:‘yyyy-MM-dd‘,realDateFmt:‘yyyyMMdd‘, vel:‘checkdate‘,maxDate:‘currentDay‘,readOnly:true})"/>
<input type="hidden" id="checkdate" name="checkreform.checkdate" />
选择的最小日期大于当前日期，后面的日期大于前面的日期,日期格式为:yyyy-mm-dd 值为yyyymmdd (日期为服务器时间)
<input type="text" id="date01" class="tdInput" onfocus="WdatePicker({dateFmt:‘yyyy-MM-dd‘,realDateFmt:‘yyyyMMdd‘,vel:‘timelimit‘,minDate:‘currentDay‘,maxDate:‘#F{$dp.$D(\‘date02\‘)}‘,readOnly:true})"/>
<input type="hidden" id="timelimit" name="checkreform.timelimit" />
<input type="text" id="date02" class="tdInput"class="tdInput" onfocus="WdatePicker({dateFmt:‘yyyy-MM-dd‘,realDateFmt:‘yyyyMMdd‘,vel:‘acceptdate‘,minDate:‘#F{$dp.$D(\‘date01\‘)}‘,readOnly:true})"/>
<input type="hidden" name="checkreform.acceptdate" id="acceptdate" />
设置默认服务器时间的前一天时间 (日期为服务器时间)
<input type="text" id="format_chcekdate_add" value="${beforeOneDay}" class="tdInput" onfocus="WdatePicker({dateFmt:‘yyyy-MM-dd‘,realDateFmt:‘yyyyMMdd‘,vel:‘chcekdate_add‘,maxDate:‘currentDay‘,readOnly:true})"/>
<input type="hidden" id="chcekdate_add" name="devicecheck.checkdate" />
设置默认服务器时间的后一天时间 (日期为服务器时间)
<input type="text" class="tdInput" value="${nextOneDay}" onfocus="WdatePicker({dateFmt:‘yyyy-MM-dd‘,realDateFmt:‘yyyyMMdd‘,vel:‘format_dutydate‘,minDate:‘%y-%M-{%d+1}‘,readOnly:true})"/>
<input type="hidden" name="leaderDuty.dutydate" id="format_dutydate" />
sql显示日期(oracle)日期存数据库用字符串用yyyymmdd是为了方便比较
substr(r.timelimit,1,4)||‘-‘||substr(r.timelimit,5,2)||‘-‘||substr(r.timelimit,7,2) as timelimit,
时间:显示为hh:实际值为:hhmi是为了两个时间段的比较方便 (日期为服务器时间)
<input type="text" id="date03" class="tdInput" onfocus="WdatePicker({dateFmt:‘HH:mm‘,readOnly:true})" /
<input type="hidden" id="starttime_update" name="dutytime.starttime" />
<input type="text" id="date04" class="tdInput" onfocus="WdatePicker({dateFmt:‘HH:mm‘,readOnly:true})" />
<input type="hidden" id="endtime_update" name="dutytime.endtime" />
var starttime=$("#date01").val();

var endtime=$("#date02").val();
endtime=endtime.substring(0,2)+endtime.substring(3,5);
$("#starttime_add").val(starttime);
$("#endtime_add").val(endtime);
sql查询显示(oracle)
substr(t.starttime,1,2)||‘:‘||substr(t.starttime,3,2) as starttime,
substr(t.endtime,1,2)||‘:‘||substr(t.endtime,3,2) as endtime,
