Question

这是现在的javascript。注意事项：

这一切都在我的机器上本地运行
food.csv与主HTML文件
我从ESRI的开发者网站获得了静态图像。

到目前为止，当我在浏览器中加载时，地图运行正常。但是，我不知道为什么CSVLayer没有被渲染。请帮忙！

<script src="https://js.arcgis.com/3.20/"></script>
<script>
var map;
require([
       "esri/map",
       "esri/layers/CSVLayer",
       "esri/symbols/PictureMarkerSymbol",
       "esri/renderers/SimpleRenderer",
       "dojo/domReady!"
       ],
       function(Map, CSVLayer, PictureMarkerSymbol, SimpleRenderer) {


           var map = new Map("map", {
              basemap: "gray",
              center: [-.1, 34.75], // longitude, latitude
              zoom: 2
            });

           // CSV Layer created using the fields we want to bring through to the client
           var layer = new CSVLayer("food.csv", {
             fields: [{name: "amount", type: "Number"}]
           });

           var logo = new PictureMarkerSymbol("http://static.arcgis.com/images/Symbols/Basic/YellowStickpin.png", 16, 11); // Define a marker image
           var simpleRenderer = new SimpleRenderer(logo); // Define a new renderer
           layer.setRenderer(simpleRenderer); //Set the simple point renderer to the feature layer

           map.addLayer(layer); // Add the layer to the map


       });


</script>

我从未设置过网络服务器。代码现在在MAMP上运行并且工作正常。
