自己写了一个展开和收起的多更能型的js效果

复制代码 代码如下:

<tbody>
<input type="hidden" id="record" value="${qr.count }">
<c:forEach items="${qr.results }" var="info" varStatus="index">
<tr id="user_info_${info.id }">
<td class="userWrapper_right_collect">
<p class="ml20 clearfix mb10">
<strong class="ex_green_fg mr10 fl">${info.sender }</strong> <span id="span_content_${info.id }" ${index.count eq 1 ? "class='fl w500'" : "class='fl symbleDot w500'" }>${info.content }</span>
</p> <a href="javascript:void(0)" onclick="cancelThisInfo(${info.id});" class="fr mr20 ex_green_fg">删除</a> <span class="fr ml5 mr5">|</span> <a href="javascript:void(0)" class="fr ex_green_fg" id="a_${info.id }" name="${index.count eq 1 ? '1' : '0' }" onclick="infoContent('${info.id}');"> <c:if test="${index.count eq 1 }" var="up">
<span id="span_${info.id }" class="ex_arrow ex_arrowUp mr5"> </span>收起
</c:if> <c:if test="${!up }">
<span class="ex_arrow ex_arrowDown mr5"> </span>展开
</c:if>
</a> <span class="fr mr10 gray"><fmt:formatDate value="${info.createTime}" pattern="yyyy-MM-dd HH:mm:ss" /></span>
</td>
</tr>
</c:forEach>
</tbody>

复制代码 代码如下:
