vue+arcgis api for javascript初始项目

先安装好node.js，vue环境了，下面开始

1。确定一个项目目录，如e:aaaa

2、cmd中转到目录，vue create arcgis-test1

就选择第一个 vue cli v4.5.11

 3。安装好之后，转到目录e:aaaaarcgis-test1

npm install --save esri-loader

4、然后就用vscode 右键打开项目了，开始编码

把components 目录下初始来的helloworld.vue 删除，添加一个map001.vue 

导包

          outline: {
            color: [255, 0, 0],

        var polygonGraphic = new this.gisConstructor.Graphic({
          geometry: polygon,

          popupTemplate:popupTemplatefill
        });
        
          var graphicsLayer = new this.gisConstructor.GraphicsLayer();
          this.map.add(graphicsLayer);
        graphicsLayer.add(pointGraphic)
        graphicsLayer.add(polylineGraphic);
        graphicsLayer.add(polygonGraphic);
      })
    }
  }

}
</script>

<!-- Add "scoped" attribute to limit CSS to this component only -->
<style scoped>
h3 {
  margin: 40px 0 0;
}
ul {
  list-style-type: none;
  padding: 0;
}
li {
  display: inline-block;
  margin: 0 10px;
}
a {
  color: #42b983;
}
</style>

5、在app.vue 中引入 map001.vue

<template>
  <div id="app">
    {{msg}}
    <br>
    <v-map001/>
  </div>
</template>

<script>
import Map001 from './components/map001.vue'//导入组件

export default {
  name:'App',
  components: {
    'v-map001': Map001
  },
  data() {
    return {
      msg: 'hello vue app'
    }
  }
}
</script>

<style>
#app {
  font-family: Avenir, Helvetica, Arial, sans-serif;
  -webkit-font-smoothing: antialiased;
  -moz-osx-font-smoothing: grayscale;
  text-align: center;
  color: #2c3e50;
  margin-top: 60px;
}
</style>

项目结构是这样：

 运行之后是这样：
