th-gis v2.8.3

th-gis组件库

帮助文档

• 项目引用

npm i th-gis -S

安装th-gis组件后需要执行后续几个步骤才能正常使用此组件

1.1 拷贝th-gis 组件安装目录中拷贝public/cdn 文件夹至使用者项目public目录中

1.2 使用者项目需要在public/index.html引入cdn文件夹中相应的js及css

具体如下:

      <link rel="stylesheet" href="cdn/gis/egis/assets/css/egis.css">
      <script src="cdn/gis/egis/egis.min-1.5.0.js"></script>
      <script>
        egis.libPath.symbolLib='cdn/gis/egis/assets/symbols/elesymbol-sym.js'
        egis.libPath.symbolData='cdn/gis/egis/assets/symbols/allSymbol.sym'
      </script>
      <script src="cdn/axios/axios-0.21.1.min.js"></script>
      <script src="cdn/gis/egis/assets/js/jquery.min.js"></script>
      <script src="cdn/gis/proj4.js"></script>
      <script src="cdn/gis/proj4leaflet.js"></script>
      <script src="cdn/gis/leaflet.polylineDecorator.js"></script>
      <script src="cdn/gis/Leaflet.Marker.SlideTo.js"></script>
      <script src="cdn/gis/leaflet-omnivore.min.js"></script>

1.3 使用者项目中安装th-gis

  在使用者src/main.js中安装th-gis,并引入th-gis样式,如下  

      import 'th-gis/lib/th-gis.css'
      import ThGis from 'th-gis'
      Vue.use(ThGis)

至此th-gis组件安装完成

一、指令说明

# 安装依赖
npm install

# 启动DEMO开发模式
npm run dev

# 打包DEMO
npm run build:demo

# 打包组件
npm run build

# 发布（npm adduser && npm login）
npm run deploy
