OpenCms - cms标签 - <cms:elementsetting>

<cms:elementsetting>用于访问元素设置。

两种访问方式：

<!-- EL -->
${cms.element.settings['setting name']}
<!-- cms tag -->
${cms:elementsetting name="setting name" default="defaultvalue" }

用途：

• 通过获取元素设置信息，对逻辑进行判断，如是否显示等。

示例：

<%@page buffer="none" session="false" trimDirectiveWhitespaces="true" %>
<%@taglib prefix="cms" uri="http://www.opencms.org/taglib/cms"%>
<%@taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core"%>
<%@taglib prefix="fmt" uri="http://java.sun.com/jsp/jstl/fmt"%>
<fmt:setLocale value="${cms.locale}" />
<cms:formatter var="content" val="value">
<div style="margin-bottom:30px;">

	<%-- Abbreviate "cms.element.settings" with "settings" --%>
	<c:set var="settings" value="${cms.element.settings}" />

	<%-- Set the title of the article via an element setting --%>
	<div class="headline">

	</div>
	<div>

		<%-- Check if the image should be shown --%>
		<c:set var="showing" value="${settings['showimage']?settings['showimage']:false}" />
		<c:if test="${showing && value.Image.isSet}">
