1.js中使用

<script>

var a='${变量名}';//注意变量名一定要和setAttribute中设置的变量名相同

</script>

2.html中使用

${变量名}

示例：

<table id="treedg" data-options="toolbar:'#tb'" >
	<c:if test="${fieldMaxLevel!=0}">
		<c:if test="${frozenFields!=null}">
			<!-- 冻结列一定要在列表最左侧，并且不可跳跃式冻结，单层次列，不具有合并属性 -->
			<thead  data-options="frozen:true">
				 <tr>
					<c:forEach var ="item" items='${frozenFields}'>
					<c:choose>
						<c:when test="${item.isCollapse>0}">
							<th data-options="field:'${item.field}',width:${item.width},halign:'${item.halign}',align:'${item.align}',formatter:${item.formatterFun},styler:${item.stylerFun}" >${item.title}  <i id="${item.field}" class="fa-minus-square-o" style="cursor:pointer" onclick="collapse(this,'${item.collapseFields}')"></i></th>
						</c:when>
						<c:otherwise>
							<th data-options="field:'${item.field}',width:${item.width},halign:'${item.halign}',align:'${item.align}',formatter:${item.formatterFun},styler:${item.stylerFun}" >${item.title}</th>
						</c:otherwise>
					</c:choose>
					</c:forEach>	
				</tr>
			</thead>
		</c:if>
		<thead>
			 <c:forEach begin="1" end="${fieldMaxLevel}" var="i">
			 		<tr>
						<c:forEach var ="item" items='${commonFields}'>
							<c:if test="${item.fieldLevel==i}">
								<c:choose>
									<c:when test="${item.isCollapse>0}">
										<th data-options="field:'${item.field}',width:${item.width},halign:'${item.halign}',align:'${item.align}',formatter:${item.formatterFun},styler:${item.stylerFun}" rowspan="${item.rowspan}" colspan="${item.colspan}">${item.title}  <i id="${item.field}" class="fa-minus-square-o" style="cursor:pointer" onclick="collapse(this,'${item.collapseFields}')"></i></th>
									</c:when>
									<c:otherwise>
										<th data-options="field:'${item.field}',width:${item.width},halign:'${item.halign}',align:'${item.align}',formatter:${item.formatterFun},styler:${item.stylerFun}" rowspan="${item.rowspan}" colspan="${item.colspan}">${item.title}</th>
									</c:otherwise>
