JavaScript ArcGIS ViewAnimation用法及代碼示例

AMD: require(["esri/views/ViewAnimation"], (ViewAnimation) => { /* code goes here */ });

ESM: import ViewAnimation from "@arcgis/core/views/ViewAnimation";

類： esri/views/ViewAnimation

繼承: ViewAnimation > Accessor

自從：用於 JavaScript 4.0 的 ArcGIS API

包含用於檢查動畫狀態的狀態屬性。當動畫具有 finished 時，視圖動畫將被解析；如果動畫是 stopped ，則被拒絕。

reactiveUtils.when(() => view.animation, function(animation) {
  console.log(animation.state); // prints out "running"
  animation.when(function(animation) {
      console.log(animation.state); // prints out "finished"
    })
    .catch(function(animation) {
      console.log(animation.state); // prints out "stopped"
    });
});

或者，可以監視狀態屬性的更改：

let animation = view.goTo(target, { speedFactor: 0.1 });
animation.watch("state", function(state) {
 switch (state) {
   case "finished":
     console.log("Animation finished.");
     break;
   case "stopped":
     console.log("Animation stopped.");
     break;
 }
});
