前端頁面接收request.setAttribute("變量名", 變量值)傳的值

1.js中使用

<script>

var a='${變量名}';//注意變量名一定要和setAttribute中設置的變量名相同

</script>

2.html中使用

${變量名}

示例：

<table id="treedg" data-options="toolbar:'#tb'" >
	<c:if test="${fieldMaxLevel!=0}">
		<c:if test="${frozenFields!=null}">
			<!-- 凍結列一定要在列表最左側，並且不可跳躍式凍結，單層次列，不具有合併屬性 -->
			<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>
