JavaScript ArcGIS ViewAnimation用法及代码示例

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

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

类： esri/views/ViewAnimation

继承: ViewAnimation > Accessor

自从：用于 JavaScript 4.0 的 ArcGIS API

包含用于检查动画状态的状态属性。当动画具有 finished 时，视图动画将被解析；如果动画是 stopped ，则被拒绝。

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，可以监视状态属性的更改：

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;
 }
});
