我很难找到这个特定 OpenLayers 数组的索引。数组看起来像这样。
Array(7)
0: PinchRotate {disposed_: false, pendingRemovals_: {…}, dispatching_: {…}, listeners_: {…},
revision_: 0, …}
1: PinchZoom {disposed_: false, pendingRemovals_: {…}, dispatching_: {…}, listeners_: {…}, revision_:
0, …}
2: KeyboardPan {disposed_: false, pendingRemovals_: {…}, dispatching_: {…}, listeners_: {…},
revision_: 0, …}
3: KeyboardZoom {disposed_: false, pendingRemovals_: {…}, dispatching_: {…}, listeners_: {…},
revision_: 0, …}
4: MouseWheelZoom {disposed_: false, pendingRemovals_: {…}, dispatching_: {…}, listeners_: {…},
revision_: 0, …}
5: DragBox {disposed_: false, pendingRemovals_: {…}, dispatching_: {…}, listeners_: {…}, revision_:
0, …}
6: PointerInteraction {disposed_: false, pendingRemovals_: {…}, dispatching_: {…}, listeners_: {…},
revision_: 0, …}
我正在尝试查找 index item = "DragBox" 的索引
我试过一个字符串和一个对象，即
let index = MapValues.map.interactions.array_.indexOf("DragBox");
let obj = DragBox
let index = MapValues.map.interactions.array_.indexOf(obj);
两者都返回了-1 ...我真的很困惑如何使用打字稿中的这个特定数组来做到这一点。
任何帮助是极大的赞赏
