arcgis的基本使用

参考：https://developers.arcgis.com/javascript/latest/guide/quick-start/

1、在html中使用

<!DOCTYPE html>
<html lang="en">
<head>
  <meta charset="UTF-8">
  <meta name="viewport" content="width=device-width, initial-scale=1.0">
  <title>Document</title>
  <link rel="stylesheet" href="https://js.arcgis.com/4.17/esri/themes/light/main.css">
  <script src="https://js.arcgis.com/4.17/"></script>
  <style>
    html,body,#map{
      height: 100%;
      width: 100%;
      box-sizing: border-box;
      overflow: hidden;
      padding: 0;
      margin: 0;
    }
  </style>
</head>
<body>
  <div id="map"></div>
  <script>
    require([
      "esri/Map",
      "esri/views/MapView"
    ], function(Map, MapView) {
      var map = new Map({
        basemap: "topo-vector"
      })
      var view = new MapView({
        container: "map",
        map: map,
        center: [-118.71511,34.09042],
        zoom: 11
      })
    })
  </script>
</body>
</html>

2、在vue项目中使用

安装arcgis官方依赖esri-loader,这个只是开发依赖,因此使用命令npm i esri-loader --save-dev来安装.
用模块的方式引入 esri-loader:

1	import esriLoader from 'esri-loader'

esriLoader有以下几个方法:

getScript () 从库里面获取 js 文件 ;
isLoaded () 检测模块是否加载完成 ;
loadModules( [ ], options) 用于加载arcgis 模块;
loadCss( url ) 用于加载css文件;

loadScript({url: “xxxxxxxx” }) 将js 加载到页面上;

<template>
	<div id="map"></div>
</template>
<script>
import esriLoader from 'esri-loader'
export default {
	mounted () {
		const options = {
			url: 'https://js.arcgis.com/4.17/init.js',
			css: 'https://js.arcgis.com/4.17/esri/themes/light/main.css'
		}
		esriLoader.loadModules([
        'esri/Map',
        'esri/views/MapView'
      ], options)
        .then(([ArcGISMap, MapView]) => {
			this.map1 = new ArcGISMap({
				basemap: 'streets-relief-vector'
			})
			this.view1 = new MapView({
				container: 'map1',
				map: this.map1,
				center: [-118.71511,34.09042],
				zoom: 4
			})
		})
	}
}
</script>
