arcgis api 3.x for js 地图加载多个气泡窗口展示(附源码下载)

前言

关于本篇功能实现用到的 api 涉及类看不懂的,请参照 esri 官网的 arcgis api 3.x for js:esri 官网 api,里面详细的介绍 arcgis api 3.x 各个类的介绍,还有就是在线例子:esri 官网在线例子,这个也是学习 arcgis api 3.x 的好素材。

由于 arcgis api 3.x for js 目前没有 GeojsonLayer, arcgis api 4.x 最新版本目前是支持了的,并且 arcgis api 3.x 提供的 Popup默认只可以弹出一个,某些情况下,用户想加载弹出多个窗口,我一直看看能不能有什么途径,比如 arcgis api 3.x 拓展之类的,对其进行改造达到绘制 Geojson 并同时弹出多个 Popup 的目的。

最终实现效果图:


实现思路

  • html 页面以及引用 js 以及 css

  • 核心 geojsonlayer.js 并且集成 Popupextended 拓展代码
    自定义一个类,继承 GraphicsLayer:
define([
"dojo/_base/declare",
"esri/dijit/PopupTemplate",
"./vendor/ncam/PopupExtended.js",
"esri/graphic",
"esri/layers/GraphicsLayer",
"esri/InfoTemplate",
"esri/graphicsUtils",
"esri/Color",
"esri/symbols/SimpleMarkerSymbol",
"esri/symbols/SimpleLineSymbol",
"esri/symbols/SimpleFillSymbol",
"esri/renderers/SimpleRenderer",
"esri/SpatialReference",
"esri/geometry/webMercatorUtils",
"esri/request",
"esri/config",
"dojo/_base/url",
"dojo/_base/lang"
], function (declare,PopupTemplate, PopupExtended, Graphic, GraphicsLayer, InfoTemplate, graphicsUtils, Color, SimpleMarkerSymbol,
SimpleLineSymbol, SimpleFillSymbol, SimpleRenderer, SpatialReference, webMercatorUtils, esriRequest, esriConfig, Url, lang
) {
return declare([GraphicsLayer], {
});
});

构造函数自定义 Popup 窗口拓展进来

constructor: function (options) {
if (options.infoTemplate !== false) {
//create a PopupTemplate
var template = new PopupTemplate({
title: "{name}",
//fieldInfos: [
// { fieldName: "name", visible: true },
// { fieldName: "address", visible: true},
// { fieldName: "phone", visible: true}
//],
extended: {
//actions: [
// { text: " IconText", className: "iconText", title: "Custom action with an icon and Text", click: function (feature) { alert("Icon Text clicked on " + "id: " + feature.attributes.id + " " + feature.attributes.name); } },
// { text: "", className: "iconOnly", title: "Custom action only using an icon", click: function (feature) { alert("Icon action clicked on " + "id: " + feature.attributes.id + " " + feature.attributes.name); } }
//],
//uses a pretty bad custom theme defined in PopupExtended.css.
scaleSelected: 1.6
}
});
