本文介绍如何在main.js中配置ArcGIS API for JavaScript，并通过define方法加载所需模块。这种方式虽然简单，但会导致页面加载时一次性下载所有相关文件。建议采用iframe隔离的方法来优化。

1.在main.js中配置ArcGIS API for JavaScript

require.config({
　　paths : {
　　　　//arcgisJS
　　　　"esri": "libs/arcgisJS/esri",
　　　　"dojo": "libs/arcgisJS/dojo",
　　　　"dojox": "libs/arcgisJS/dojox",
　　　　"dijit": "libs/arcgisJS/dijit",
　　}
});

2.加载所需的模块

define([
        "esri/urlUtils",
        "esri/config",
        "esri/map",
        "esri/layers/ArcGISTiledMapServiceLayer",
        "esri/geometry/Point",
        "esri/graphic",
        "esri/SpatialReference",
        "esri/tasks/GeometryService",
        "esri/tasks/ProjectParameters",
        "esri/tasks/FeatureSet",
        "esri/dijit/PopupMobile",
        "esri/geometry/Extent",
        "dojo/dom-construct"
        ], function (app, urlUtils, esriConfig, Map, ArcGISTiledMapServiceLayer, Point, Graphic,
                SpatialReference, GeometryService, ProjectParameters, FeatureSet, PopupMobile,
                Extent, domConstruct) {
});
