简单笔记 ：
WdatePicker.js
要使结束时间大于开始时间只要在线束时间的 minDate:'#F{$dp.$D(\'stimeParam\')}' 即可：不多说
详细代码如下：
<tr>
<td>开始时间：</td>
<td><input type="text" class="Wdate" id="stimeParam" name="stimeParam" onfocus="WdatePicker({skin:'whyGreen',dateFmt: 'yyyy-MM-dd HH:mm:ss', minDate: '${minDate}', maxDate: '${maxDate}' }) " value="${stimeParam}"/></td>
<td>结束时间：</td>
<td><input type="text" class="Wdate" id="timeParam" name="timeParam" onfocus="WdatePicker({skin:'whyGreen',dateFmt: 'yyyy-MM-dd HH:mm:ss', minDate:'#F{$dp.$D(\'stimeParam\')}', maxDate: '${maxDate}' }) " value="${inputDateStr}"/></td>
</tr>

<input type="text" class="Wdate" id="startTime" onfocus="WdatePicker({dateFmt:'yyyy年MM月',maxDate:'#F{$dp.$D(\'endTime\')}'})"/> <input type="text" class="Wdate" id="endTime" onfocus="WdatePicker({dateFmt:'yyyy年MM月',minDate:'#F{$dp.$D(\'startTime\')}'})"/>
