Vue+ ArcGIS JavaScript APi详解

作者:安迪小宝

这篇文章主要介绍了Vue+ ArcGIS JavaScript APi,文中需要注意ArcGIS JavaScript3.x 和ArcGIS JavaScript 4.x框架差异较大,本文从环境搭建开始到测试运行给大家讲解的非常详细,需要的朋友可以参考下

版本

Vue 2

ArcGIS JavaScript 4.22

注意 ArcGIS JavaScript3.x 和ArcGIS JavaScript 4.x框架差异较大

环境搭建

新建vue

可以使用vue ui创建项目

增加ArcGIS JavaScript 包引用

package.json

 "dependencies": {
    "core-js": "^3.8.3",
    "vue": "^2.6.14",   
    "@arcgis/core":"4.22.2",
    "ncp":"^2.0.0"
  },
  "devDependencies": {
    "@babel/core": "^7.12.16",
    "@babel/eslint-parser": "^7.12.16",
    "@vue/cli-plugin-babel": "~5.0.0",
    "@vue/cli-plugin-eslint": "~5.0.0",
    "@vue/cli-service": "~5.0.0",
    "eslint": "^6.8.0",
    "eslint-plugin-vue": "^5.2.3",    
    "vue-template-compiler": "^2.6.14"  
  },

ncp: 主要用于拷贝资源信息

@arcgis/core 是arcgis_js仓库

拷贝资源信息

package.json中配置copy命令

 "scripts": {
    "serve": "vue-cli-service serve",
    "build": "vue-cli-service build",
    "lint": "vue-cli-service lint",
    "copy": "ncp ./node_modules/@arcgis/core/assets ./public/assets"
  },

安装完依赖后运行 copy命令

yarn 
yarn copy
yarn serve
-------------------
npm i
npm run copy
npm run serve

运行完copy命令后,会将arcgis相关资源拷贝到public/assets目录下

全局引入

main.js

import '@arcgis/core/assets/esri/themes/light/main.css'
import esriConfig from '@arcgis/core/config.js'
esriConfig.assetsPath = './assets'

页面测试

    <div id="map" class="map" v-show="flag == 'map'">
