遍历map并判断key的值
jsp页面：三种方法输出
<c:forEach items="${myMap}" var="mapV" varStatus="status">
<tr>
<td>${status.index+1}</td>
<td class="ygdl">
<%--
<c:if test="${mapV.key==\'v0\'||mapV.key==\'v1\'||mapV.key==\'v2\'||mapV.key==\'v3\'||mapV.key==\'v4\'||mapV.key==\'v5\'||mapV.key==\'v6\'||mapV.key==\'v7\'||mapV.key==\'v8\'}"></c:if>
<c:if test="${!(mapV.key==\'v0\'||mapV.key==\'v1\'||mapV.key==\'v2\'||mapV.key==\'v3\'||mapV.key==\'v4\'||mapV.key==\'v5\'||mapV.key==\'v6\'||mapV.key==\'v7\'||mapV.key==\'v8\')}">${mapV.key}</c:if>
--%>
<%--
<c:if test="${mapV.key.startsWith(\'v\')}"></c:if>
<c:if test="${!mapV.key.startsWith(\'v\')}">${mapV.key}</c:if>
--%>
<c:if test="${fn:startsWith(mapV.key, \'v\')}"></c:if>
<c:if test="${!fn:startsWith(mapV.key, \'v\')}">${mapV.key}</c:if>
</td>
<td class="wgdl"><fmt:formatNumber value="${mapV.value }" pattern="0.00" /></td>
</tr>
</c:forEach>
