JS中使用EL表达式

    <script type="text/javascript">  
        $(function () {  
            new BacklogOverview("${param.alert}");  
        });  
    </script>  

<c:set var="contextPath" value="${pageContext.request.contextPath}" scope="application"/>  
    <script>  
        <%--JS gloable varilible--%>  
        var contextPath = "${contextPath}";  
</script>

config.filebrowserImageUploadUrl = contextPath + "/ckeditor/upload.htm";
