一.jsa.'${pageContext.request.contextPath}'//结果:/projectNameb.'<%=request.getContextPath()%>'//结果:/projectName用法：<script>function searchData(dom){   $(dom).attr('disabled', true);   var url = '${pageContext.request.contextPath}/OrderController/getOrders.mmx?'+$('#orderForm').serialize();   var url = '<%=request.getContextPath()%>'+'/OrderController/getOrders.mmx?'+$('#orderForm').serialize();   $('#dataDiv').html('数据加载中...').load(url, function(){      $(dom).attr('disabled', false);   });}<script>

二.jspa.<%=request.getContextPath()%>//结果:/projectNameb.${pageContext.request.contextPath}//结果:/projectName用法：<link rel="stylesheet" type="text/css" href="${pageContext.request.contextPath}/order/css/OrderCss.css" /> <link rel="stylesheet" type="text/css" href=<%=request.getContextPath()%>+"/order/css/OrderCss.css" />
