常用的el表達式

常用的el表達式

一、遍歷：

<c:forEach items="${resumePager.pageInfo.listPages}" var="i">
    <c:choose>
        <c:when test="${resumePager.pageInfo.page == i}">
            <li class="page-num current"><a href="#topAnchor"
                                            οnclick="loadPageFrm(${i});">${i}</a>
            </li>
        </c:when>
        <c:otherwise>
            <li class="page-num"><a href="#topAnchor"
                                    οnclick="loadPageFrm(${i});">${i}</a>
            </li>
        </c:otherwise>
    </c:choose>
</c:forEach>

 

二、選擇

<c:choose>
        <c:when test="${resumePager.pageInfo.page == i}">
            <li class="page-num current"><a href="#topAnchor"
                                            οnclick="loadPageFrm(${i});">${i}</a>
            </li>
        </c:when>
        <c:otherwise>
            <li class="page-num"><a href="#topAnchor"
                                    οnclick="loadPageFrm(${i});">${i}</a>
            </li>
        </c:otherwise>
    </c:choose>

 

三、判斷

<c:if test="${not empty items.resumeName}">
    <dt class="w100"><input type="checkbox" class="item-check" name=""/><a
            href="${pageContext.request.contextPath}/Resume/resumeDetail?id=${items.id}" target="_blank">${items.resumeName}</a></dt>
</c:if>
<c:if test="${not empty items.resumeName}">
    <dt class="w100"><input type="checkbox" class="item-check" name=""/>

<a          href="${pageContext.request.contextPath}/Resume/resumeDetail?id=${items.id}" target="_blank">${items.resumeName}</a></dt>
</c:if>

<c:if test="${ empty items.resumeName}">
    <dt class="w100"><input type="checkbox" class="item-check" name=""/><a
            href="${pageContext.request.contextPath}/Resume/resumeDetail?id=${items.id}" target="_blank"> </a></dt>
</c:if>

 

 

 

四、判斷是否爲空

${ empty items.resumeName}  爲空

${not empty items.resumeName} 不爲空

 

五、三目運算

${items.gender==1?"男":"女"}
