<input type="text" id="ueLineTime" name="ueLineTime" size="20" class='easyui-validatebox Wdate'

onFocus="WdatePicker({el:'ueLineTime',dateFmt:'yyyy-MM-dd',minDate:'#F{$dp.$D('usLineTime')}'})"

value="<fmt:formatDate value="${product.ueLineTime}" pattern ="yyyy-MM-dd" />" required="true"/>

</td></tr>

Note: ueLineTime is the current time and mainly controls the date control.

MaxDate is a maximum of the current date can only be selected, greater than the current date gray, can not be selected.

The principle of minDate is the same as above.
