本文主要是介绍ArcGIS for js 4.x FeatureLayer 点选查询，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！
示例：
代码如下：
<template><view id="mapView"></view></template><script setup>
import "@arcgis/core/assets/esri/themes/light/main.css";
import Map from "@arcgis/core/Map.js";
import MapView from "@arcgis/core/views/MapView.js";
import TitleLayer from "@arcgis/core/layers/TileLayer.js";
import FeatureLayer from "@arcgis/core/layers/FeatureLayer.js"
import PopupTemplate from "@arcgis/core/PopupTemplate.js"
import Popup from "@arcgis/core/widgets/Popup.js";
import Locate from "@arcgis/core/widgets/Locate.js";
import Compass from "@arcgis/core/widgets/Compass.js";
import Graphic from "@arcgis/core/Graphic.js";
import SimpleFillSymbol from "@arcgis/core/symbols/SimpleFillSymbol.js";
import { onMounted } from "vue";onMounted(()=>{initMap();
});const initMap = function(){const map = new Map({basemap:{baseLayers:[new TitleLayer({url:"http://map.geoq.cn/arcgis/rest/services/ChinaOnlineCommunity_Mobile/MapServer"})]}});// 创建PopupTemplate实例var popupTemplate = new PopupTemplate({//title:"{objectid}",title:"<div style='color: red'>{objectid}</div>",content:`图斑类型:{tblx}<br/>图斑面积:{tbmj}<br>`});// 加载FeatureLayerconst featureLayer = new FeatureLayer({url:"http://116.141.0.114:48080/geoscene/rest/services/%E8%80%95%E4%BF%9D/%E5%8F%8C%E9%98%B3%E5%8C%BA%E5%9B%BE%E6%96%91/FeatureServer/0",outFields: ["*"], //加载所有要素字段opacity:0.5,//透明度//popupTemplate: TuCeng03TC, //加载模板,//definitionExpression: "",// 筛查labelsVisible:false,//禁用显示标注// 渲染renderer: {type: "simple",symbol: {type: "simple-fill",//simple-line(线)、simple-fill（面）style: "solid",// solid 全部填充、cross十字交错、diamond菱形、square矩形、triangle三角形color: [255,20,60, 0.4],outline: {color: [255, 0, 0, 1],width: 2,},},},// 配置popupTemplatepopupTemplate:popupTemplate//配置默认的信息模板-文本型/* popupTemplate:{//title:"{objectid}",title:"<div style='color: red'>{objectid}</div>",content:`图斑类型:{tblx}<br/>图斑面积:{tbmj}<br>`} *///配置默认的信息模板-表格型/*popupTemplate:{title:"{objectid}",content:[{type:"fields",fieldInfos:[{fieldName:"tblx",label:"图斑类型"},{fieldName:"tbmj",label:"图斑面积"}]}]}*/});// 添加featureLayer(两种方法都可以)//mapView.map.add(featureLayer);map.add(featureLayer);// 创建并配置信息窗口对象const popup = new Popup({visibleElements:{// 对可见元素进行配置collapseButton:false,// 禁用折叠按钮actionBar:false,// 禁用动作条closeButton:true// 打开右上角关闭按钮},//container:"popup_image",//设置自定义组件（类似mapView）dockOptions:{buttonEnabled:false,// 禁用停靠按钮// 弹窗位置position: "center",// 当窗口小于100*100像素时，固定弹出窗口breakpoint: {width: 100,height: 100}}});// mapView容器 const mapView = new MapView({// 长春坐标系center:[125.331345,43.8328],// 初始层级zoom:10,container:"mapView",map:map,constraints: {minZoom: 10,// 最小层级maxZoom: 19 // 最大层级},popup:popup// 关联popup});// 清除底部powered by ESRImapView.ui.remove("attribution");//mapView点击事件mapView.on(["click"],function(event){mapView.hitTest(event).then(function(response){let clickLayer = response.results.filter((result) => {return result.graphic.layer === featureLayer;});// 获取绘制let graphic = clickLayer[0].graphic;// 点击后定位//mapView.goTo(graphic);mapView.goTo({target:graphic,zoom:13})});});}</script><style lang="scss" scoped>#mapView{width: 100%;height:100vh;padding: 0;margin: 0;}</style>
定位也可以写成下面的方式：
// 创建PopupTemplate实例var popupTemplate = new PopupTemplate({content:(feature)=>{// 定位mapView.goTo({target:feature.graphic,zoom:13});for(let key in feature.graphic.attributes){if(feature.graphic.attributes[key]){// 输出全部属性值console.log(feature.graphic.attributes[key]);}}}});这篇关于ArcGIS for js 4.x FeatureLayer 点选查询的文章就介绍到这儿，希望我们推荐的文章对编程师们有所帮助！
