吐血推荐：网上搜了很久关于webgis地图属性表输出到Excel表，并没能找到相关有价值的信息，在小白面前，这就是一脸懵x啊！网上要么是关于前端如何在页面上直接导出excel，和webgis半毛钱关系没有，要么查看arcgis api for javascript 的帮助文档，里面有的实例是显示属性表信息，如何同时显示并能输出excel表的文章介绍，没找到。。那只能通过看代码，进行改进来实现上面的两种功能，终于终于。。。。找到了他们之间的联系，实现出来了！！
1、首先我已经发布过地图并找到URL，了解直接要发布地图的属性表信息
2、我实现的代码功能是通过查询一个区域的名称，找到该区域的经纬值，并输出到excel中：
3、将相关信息查询出来，显示页面中，实现的结果如下：
4、最关键一步，将这些信息输出到excel中去！点击按键，如图
5、代码部分：
