求这种效果${obj.time}.substring(0,10)

[潇水汀寒]

${bi.start_time}是String还是Date呢
我想只显示日期
这种效果 ${bi.start_time}.substring(0,10)怎么写

[MiceRice]

似乎是：(new String(${bi.start_time})).slice(0,10);

[潇水汀寒]

<script type="text/javascript">
	function getDate(param){
		document.write(param.slice(0,10));
	}
</script>

	<c:if test="${requestScope.list!=null }">
		<c:forEach var="bi" items="${requestScope.list}"
			varStatus="loopStatus">
			<tr class="${loopStatus.index % 2 == 0 ? 'even' : 'odd'}">
				<td>${bi.applicant }</td>
				<td><script>
					getDate('${bi.start_time}')
				</script>
				</td>
				<td>${bi.end_time }</td>
				<td>${bi.days }</td>
				<td>${bi.status }</td>
				<td>${bi.reason }</td>
			</tr>
		</c:forEach>
	</c:if>
