my97时间控件

1.开始时间小于结束时间、结束时间大于开始时间、并且都有最小固定的时间

  <tr>
    	<td width="18%" class="right">开始时间：</td>
        <td width="32%" class="reg">
         <input type="text" id="startTime" name="startTime" onfocus="WdatePicker({dateFmt:'yyyy-MM-dd HH:mm:ss',minDate:'${startDate}',maxDate:'#F{$dp.$D(\'endTime\')||\'${endDate}\'}'})" class="Wdate validate[required]"  style="width:130px;" readonly="readonly"/><span class="star">*</span>
        </td>
        <td width="18%" class="right">结束时间：</td>
        <td width="32%" class="reg">
         <input type="text" id="endTime"  name="endTime" onfocus="WdatePicker({dateFmt:'yyyy-MM-dd HH:mm:ss',minDate:'#F{$dp.$D(\'startTime\')||\'${startDate}\'}'})" class="Wdate validate[required]"  style="width:130px;" readonly="readonly"/><span class="star">*</span>
        </td>
    </tr>

 2.开始时间 结束时间 间隔固定最大 90天;

<p>开始时间：</p><input type="text" id="Stime" name="startTime"  class="Wdate" runat="server" value="" style="width:130px;" onfocus="startTimeFocus();"/>
	   	<p>结束时间：</p><input type="text" id="Etime" name="endTime" class="Wdate" runat="server" value="" style="width:130px;" onfocus="endTimeFocus();"/></span>

        dateFmt:'yyyy-MM-dd'
    });
}
 
function endTimeFocus() {
    return WdatePicker({
        minDate:'#F{$dp.$D(\'Stime\')}',
        maxDate:getMaxDate(),
        dateFmt:'yyyy-MM-dd'
    });
