单个WEB页面展示多个Echarts图表

单个WEB页面展示多个Echarts图表

 

由于业务的需要，需要把多个数据报表放到同一个页面上，同时，对该页面添加一键导出EXCEL、WORD、PDF功能

 

Echarts初级上手比较简单，直接依葫芦画瓢照着DEMO修改，拉取数据展示即可，但如果同时需要把十几个、几十个展示出来且放到同一个页面上就稍微复杂些了，需要考虑到页面拉取数据并发问题，数据拉取速率、界面展示等等诸多问题

最开始尝试用原生javaweb来直接对多个div进行异步取值赋值操作，效果不太好，最开始设想的就是一个DIV，对应一个echarts的展示图表，想想对js这边函数有极大的压力，且有许多重复的js函数，所以就换了一种思路

 

核心思想就是，模块化地对需要展示的数据进行操作，不同的图表调不同的函数，求同存异

JS主要都是ECHARTS和jQuery相关的，还有一些是导出功能需要用到的
