自从：用于 JavaScript 4.0 的 ArcGIS API

用法说明

Accessor.set函数(或属性)的定义如下：

set (path, value) {*}


设置属性的值。

使用属性名称和值调用 set() 以更改属性的值。

// setting the basemap of the map
map.set("basemap", "topo-vector");
// is equivalent to
map.basemap = "topo-vector";

// currying set
let updateViewScale = view.set.bind(view, "scale");
updateViewScale(5000);

set() 可以使用属性和值的路径来调用。如果路径中的属性不存在，则不会设置该属性。

// updating the title of the basemap
map.set("basemap.title", "World Topographic Map");

// is equivalent to
if (map.basemap != null) {
  map.basemap.title = "World Topographic Map";
}

可以将具有键值对的对象传递到 set() 以一次更新多个属性。

// setting a viewpoint on the view
view.set({
  center: [-4.4861, 48.3904],
  scale: 5000
});

// currying set
let updateView = view.set.bind(view);

updateView({
  center: [-4.4861, 48.3904],
  scale: 5000
});

参数：

类型说明
path String|Object

要设置的属性的路径，或键值对的对象
value *

要在属性上设置的新值。

返回：

类型 说明
* 实例。
