Question

将dojo代码升级到2.x后，我收到一个非常奇怪的错误。该函数定义为：

var map; //Globally defined   
Require(["esri/map", "esri/geometry/Point"], function(Map, Point) {    

map = new Map("map", {infoWindow: popupWin, extent: initialExtent, sliderStyle: 'small', sliderPosition: "bottom-right", navigationMode: 'css-transforms'});  
var a = (map.toMap(new Point(0, 0));  
});

但是，当我在控制台中执行map.toMap（）函数时，它工作正常。有谁知道我哪里出错了？它变得如此令人困惑......

您是否尝试过domReady!？它将导致函数等待，直到加载DOM。

require([
    "esri/map",
    "esri/geometry/Point",
    "dojo/domReady!"
], function(){
    // will not run until DOM is finished loading
});

否则可能是您的包含尚未注册，您可以通过将代码包装在dojo/ready中来解决。

require([
    "esri/map",
    "esri/geometry/Point",
    "dojo/ready"
], function(map, Point, ready){
    ready(function(){
        // This function won't run until the DOM has loaded and other modules that register
    });
});

类型错误：未定义不是函数（esri映射）
