前言

關於本篇功能實現用到的 api 涉及類看不懂的，請參照 esri 官網的 arcgis api 3.x for js：esri 官網 api，裏面詳細的介紹 arcgis api 3.x 各個類的介紹，還有就是在線例子：esri 官網在線例子，這個也是學習 arcgis api 3.x 的好素材。javascript

因爲 arcgis api 3.x for js 目前沒有 GeojsonLayer， arcgis api 4.x 最新版本目前是支持了的，而且 arcgis api 3.x 提供的 Popup默認只能夠彈出一個，某些狀況下，用戶想加載彈出多個窗口，我一直看看能不能有什麼途徑，好比 arcgis api 3.x 拓展之類的，對其進行改造達到繪製 Geojson 並同時彈出多個 Popup 的目的。css

最終實現效果圖：
html

實現思路java

html 頁面以及引用 js 以及 css

核心 geojsonlayer.js 而且集成 Popupextended 拓展代碼
自定義一個類，繼承 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], {
});
});

構造函數自定義 Popup 窗口拓展進來jquery

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
}
});
