前几天再做项目的时候用到了echarts的map显示。由于官网上的例子有限,我要在例子上进行扩展,很是搞了一番功夫。话不多说了,看例子:
1.echarts作为百度的一个开源插件,在有些地方可以做的很炫。主要是支持多种方式可以使用。
在echarts官网上下载:http://echarts.baidu.com/doc/example.html
现在看看怎么在jsp里面使用:
模块化单文件引入:这是百度推荐使用的。个人认为不咋好用,因为这要支持require。
标签式单文件引入:这个跟我们引入普通的js是一样的,下面的讲解主要是以这个方式为主。
自1.3.5开始,ECharts提供标签式引入。如果你的项目本身并不是基于模块化开发的,或者是基于CMD规范(如使用的是seajs),那么引入基于AMD模块化的echarts可能并不方便,我们建议你采用srcipt标签式引入,忘掉require。Srcipt标签引入echarts后将可以直接使用两个全局的命名空间:echarts,zrender,可参考ECharts标签式引入,需要注意的是excanvas依赖body标签插入Canvas节点去判断Canvas的支持,如果你把引用echarts的script标签放置head内在IE8-的浏览器中会出现报错,解决的办法就是把标签移动到body内(后)。
标签式引入环境中,常用模块的引用可通过命名空间直取,同模块化下的路径结构,如:
echarts.config = require('echarts/config'), zrender.tool.color = require('zrender/tool/color')
//from echarts example <body> <div id="main" style="height:400px;"></div> ... <script src="example/www2/js/dist/echarts-all.js"></script> <script> var myChart = echarts.init(document.getElementById('main')); var option = { ... } myChart.setOption(option); </script> </body>
可以直接引入的单文件如下:
- dist/echarts-all.js : 经过压缩,全图表,包含world,china以及34个省市级地图数据
- source/echarts-all.js : 未压缩,全图表,包含world,china以及34个省市级地图数据,可用于调试
下面这个例子是显示iPhone在中国的销量:

<script type="text/javascript" src="../echarts-all.js"></script> 这个就是echarts全部js,直接引入即可。
