昨天遇到了这样一个问题,从数据库查询出来数据,将数据用柱形图的方式展示到页面,可万万没想到的是,试来试去都不行,只好在网上找,查询了很多demo但是给的例子也还是行不通,该引入的js文件都引了,该导的jar包也都导入了,思前想后也没有找到答案。
这是原先的引入js的顺序:
<script type="text/javascript" src="${pageContext.request.contextPath }/js/highcharts.js"></script>
<script type="text/javascript" src="${pageContext.request.contextPath }/js/exporting.js"></script>
<script type="text/javascript" src="${pageContext.request.contextPath }/js/jquery-2.1.4.min.js"></script>
highcharts.js里面依赖jquery,我把jquery放到最后一个引入的,导致了错误的发生,根本原因就在于依赖关系、执行顺序。然后更改为:
<script type="text/javascript"
src="${pageContext.request.contextPath }/js/jquery-2.1.4.min.js"></script>
<script type="text/javascript"
src="${pageContext.request.contextPath }/js/highcharts.js"></script>
<script type="text/javascript"
src="${pageContext.request.contextPath }/js/exporting.js"></script>
重启服务器,运行,结果柱形图出来了。很多小细节太容易忽视了
整个页面代码如下:
<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>
<%
String path = request.getContextPath();
String basePath = request.getScheme() + "://" + request.getServerName() + ":" + request.getServerPort()
+ path + "/";
%>

});
});
</script>
