jsp里input中获取当前时间，与WdatePicker配合使用

<script language="javascript" type="text/javascript" src="${ctx}/js/My97DatePicker/WdatePicker.js"></script>

<script type="text/javascript">

<%  
          java.text.SimpleDateFormat formatter = new java.text.SimpleDateFormat("yyyy-MM-dd");
          java.util.Date currentTime = new java.util.Date();//得到当前系统时间
          String str_date = formatter.format(currentTime); //将日期时间格式化 
 %> 

if($.trim($("#begintime_id").val())!="")
{
      if($.trim($("#endtime_id").val())=="")
      {
            alert("结束时间不允许为空！");
            return;
      }
}
if($.trim($("#endtime_id").val())!="")
{
      if($.trim($("#begintime_id").val())=="")
      {
            alert("开始时间不允许为空！");
            return;
      }
}

</script>

<input id="begintime_id" name="begintime" type="text" onFocus="WdatePicker({maxDate:'#F{$dp.$D(\'endtime_id\')}'})" readonly="readonly" value="<%=str_date%>" class="Wdate" Style="{86px}"/>
