问题 Is it possible to have a single layer visible on the map in this ESRI tutorial LayerList widget ? Each time you click on a layer, the previous one should deactivate. So you always have only one layer on the map. Michelle 回答1: I managed to write a code for you .

问题 I try to add a feature to an ArcGIS feature service through Arcgis JavaScript API and dojo/request .

问题 Is it possible to fetch the number of items with a certain property against the property from a CSVLayer in ArcGIS Javascript API? This is the csv file. My intent is to Category 0 - 1 Category 1 - 0 Category 2 - 1 Category 3 - 0 if we are showing Legends from the "Category" property and all the documents are in the view. Also is it possible to filter the items based on the same property? Also is it possible to show the details in a Pie Chart? 回答1: You can use client side queries to retrieve

Esri proxy for Angular 7 project to screenshot

由 蹲街弑〆低调 提交于 2019-12-11 03:51:18
问题 My team is currently working on a web application with angular 7 front end and .net core 2.1 back-end. One of tasks i need to do is to grab a screenshot and attach it to an email. The web application has an esri-map. For the purposes of capturing the screenshot i am using html2canvas package. It works as expected except for the part that it doesn't capture the esri map content. It captures everything else except the esri-map. For the html2canvas function call, i set the allowTaint property

问题 I feel like there is something really simple that I am missing here. I've got a class that I am building out that uses Esri ArcGIS API, but when I import the type definitions from the arcgis-js-api 's d.ts file, I get the typescript error "Cannot use 'new' with an expression whose type lacks a call or construct signature." Ex: import * as IMap from 'esri/Map'; export class Foo { bar: (Map: IMap) { const map = new Map(); // <-- error here } } relevant snippets from the d.ts file: declare

ArcGIS JavaScript API 3.9 - mouse-drag events don´t work in Internet Explorer 11

由 走远了吗. 提交于 2019-12-07 12:18:32
问题 I am facing a problem with mouse-drag event form ArcGIS API for JavaScript 3.9 in Internet Explorer 11 The code is below: map.on("mouse-drag", zobraudalost); function zobraudalost() { alert("test"); } The problem is that, this event doesn´t fire at IE 11 (as well as mouse-drag-start, mouse-drag-end). But on the other browsers it works fine (IE9, Firefox, Chrome). The other problem is that other mouse events (click, mouse-move, etc) work fine on IE 11, so the problem is only with the mouse
