大多数程序/游戏的光标/指针锁定API失败。

我们可以使用以下示例代码来解决光标/指针锁定API的问题。该代码使用了requestPointerLock和exitPointerLock方法来锁定和释放光标/指针。请注意，我们需要在用户与游戏/程序之前获取光标/指针的焦点。

let canvas = document.getElementById('my-canvas');

canvas.onclick = function() {
  canvas.requestPointerLock();
}

document.addEventListener('pointerlockchange', lockChangeAlert, false);

function lockChangeAlert() {
  if (document.pointerLockElement === canvas) {
    console.log('The pointer lock status is now locked');
  } else {
    console.log('The pointer lock status is now unlocked');  
  }
}

document.addEventListener('keydown', releasePointerLock, false);

function releasePointerLock() {
  document.exitPointerLock();
}
