Question

使用ArcGIS Server Javascript Api我遇到了在地图上显示主页按钮和地图概述的问题。因为什么原因主页按钮没有显示地图这是我的脚本是：

<script>
  require([
    "esri/map", 
    "esri/dijit/OverviewMap", "dojo/parser","dijit/layout/BorderContainer", "dijit/layout/ContentPane",
    "esri/dijit/HomeButton", "esri/layers/FeatureLayer", "dojo/dom-construct", "dojo/domReady!"
  ], function(
      Map, OverviewMap,
  parser, HomeButton, FeatureLayer       
     ) {
    parser.parse(); 
    var map = new Map("mapDiv", {
      basemap: "topo",
      center: [-126.416, 55.781],
      zoom: 6
    });
  //===================================================== Overview
    var overviewMapDijit = new OverviewMap({
      map: map,
      visible: true
    });
    overviewMapDijit.startup();

 //===================================================== Shapefile
    //add a layer to the map
    var featureLayer = new FeatureLayer("http://somewhere/1", {
      mode: FeatureLayer.MODE_ONDEMAND,
    });
 map.addLayer(featureLayer);

 //===================================================== Home Button
var home = new HomeButton({
map: map
}, "HomeButton");
 home.startup();

  });
 </script>

和Home Button的CSS是：

#HomeButton { position: absolute;  top: 120px; left: 50px;  z-index: 2; }

你能告诉我为什么会这样吗？

Answer 1

从我所看到的是你的“esri / dijit / HomeButton”模块加载到第6位，而在写function(Map, OverviewMap, parser, HomeButton, FeatureLayer)时你已经在第4位提到了HomeButton参数位置。

如果您的模块也位于第4位

require([
    "esri/map", 
    "esri/dijit/OverviewMap", "dojo/parser", "esri/dijit/HomeButton", "dijit/layout/BorderContainer", "dijit/layout/ContentPane", "esri/layers/FeatureLayer", "dojo/dom-construct", "dojo/domReady!"
  ]

以及功能在正确位置的所有参数，然后一切都应该顺利
