javascript - 创建点、弹出窗口、圆、转换坐标问题(Arcgis JS 4.6 API)

Question

我想在 basemap 项目上做一些简单的事情。

• 例如创建一个圆圈。
• 单击创建的点时创建弹出窗口。
• 将 lat long 转换为 x y

我该如何做这些事情？

Answer 1

    var pt = new Point({
      longitude: 99.909550,
      latitude: 99.751906

  });



  var lineAtt = {
      Name: "fill",
      Owner: "fill",
      Length: "999 km"
  };

    // Create a graphic and add the geometry and symbol to it
  var pointGraphic = new Graphic({
      geometry: pt,
      symbol: markerSymbol,
      attributes: lineAtt,
      popupTemplate: { // autocasts as new PopupTemplate()
          title: "{Name}",
          content: [{
              type: "fields",
              fieldInfos: [{
                  fieldName: "Name"
              }, {
                  fieldName: "Owner"
              }, {
                  fieldName: "Length"
              }]
          }]
      }
  });

我找到了单击创建的点时打开弹出窗口的解决方案。
